Abstract:
The manufacturing industry must diverge from a ‘take, make and waste’ linear production paradigm towards more circular economies. Truly sustainable, circular economies are intrinsically tied to renewable resource flows, where vast quantities need to be available at a central point of consumption. Abundant, renewable carbon feedstocks are often structurally complex and recalcitrant, requiring costly pretreatment to harness their potential fully. As such, the heat integration of supercritical water gasification (SCWG) and aerobic gas fermentation unlocks the promise of renewable feedstocks such as lignin. This study models the technoeconomics and life cycle assessment (LCA) for the sustainable production of the commodity chemicals, isopropanol and acetone, from gasified Kraft black liquor. The investment case is underpinned by rigorous process modelling informed by published continuous gas fermentation experimental data. Time series analyses support the price forecasts for the solvent products. Furthermore, a Monte Carlo simulation frames an uncertain boundary for the technoeconomic model. The technoeconomic assessment (TEA) demonstrates that production of commodity chemicals priced at ~US$1000 per tonne is within reach of aerobic gas fermentation. In addition, owing to the sequestration of biogenic carbon into the solvent products, negative greenhouse gas (GHG) emissions are achieved within a cradle-to-gate LCA framework. As such, the heat integrated aerobic gas fermentation platform has promise as a best-in-class technology for the production of a broad spectrum of renewable commodity chemicals.

Abstract:
Several algorithms have been developed for building-attached photovoltaic system (BAPV) planning in educational institute based on PV capacity. Fewer studies on optimization algorithms for BAPV system planing on campus have been reported which considers a technoeconomic assessment. Therefore, a well-known robust algorithm is used as an optimization technique of BAPV system and considers technoeconomic assessment on campus. This paper presents a combination of analytical hierarchy process (AHP) with fuzzy theory (fuzzy AHP) for selecting a suitable and optimal design of BAPV system on academic campus. The BAPV system design is based on roof area and load profile at the project site. Five BAPV systems have been designed using five different types of PV. The design was comprehensively assessed by experts through a questionnaire with pairwise comparison model. Fuzzy AHP used to consider the qualitative and quantitative assessments that can affect the selection process. The comprehensive assessment in criteria consists of sizing systems, technical, economic, and environmental perspectives as criteria. The perspective is divided into 13 subcriteria. The results show degree of importance from the criteria-based fuzzy AHP as follows: technical > economic > environment > sizing system. Based on the assessment of criteria and subcriteria, design with monocrystalline is most suitable and polycrystalline as the least suitable design for BAPV system connected to grid and battery energy storage system in case study.

Abstract:
Innovative technologies and sources of energy must be developed to replace fossil fuels and contribute to the reductions of emissions of greenhouse gases associated with their use. In this perspective, algal biofuels are generating substantial awareness in many countries. As of today, it has been shown that it is scientifically and technically possible to derive the desired energy products from algae in the laboratory. The question lies, however, in whether it is a technology that merits the support and development to overcome existing scalability challenges and make it economically feasible. In this context, the overall purpose of this study is to provide an integrated assessment of the potential of microalgae as a source to produce biofuels, while confronting it with competing emerging biofuel technologies. It is intended to provide a comprehensive state of technology summary for producing fuels from algal feedstocks and to draw some insights upon the feasibility and technoeconomic challenges associated with scaling up of processes.

This thesis looked at a biorefinery pilot plant that converted lignin in black liquor into biofuel. A heat/mass balance was made which was used to create a heat/mass balance for a theoretical large-scale plant. This then created the CAPEX for building the plant. OPEX for the largescale plant and income from sold biofuels was calculated and payback time found. This was done for three different cases with different flows and yield to optimize the plant. A sensitivity analysis was then made to find the most important parameters regarding CAPEX, OPEX and payback time.

Abstract:
Electric vehicles are the main technology currently being pursued to reduce dependence on fossil fuels in the transportation sector. These vehicles provide both reduced greenhouse gas emissions and decreased operating costs when compared to conventional internal combustion vehicles, while providing the flexibility to use both renewable and fossil energy. However, these vehicles have seen limited consumer adoption due to their large purchase prices and limited driving range. Both purchase price and driving range are related to the large onboard battery systems required for electric vehicle travel. One solution to decrease dependence on large battery systems has focused on charging vehicles in-motion using wireless power transfer. In-motion charging of electric vehicles would allow for longer range travel with smaller onboard battery systems which would lead to cheaper vehicles and, in turn, greater consumer acceptance. Wireless power transfer is commonly used for small electronics (i.e. cell phones), but has seen limited use on large scale projects. Therefore, limited work has been done to understand the feasibility of in-motion charging of electric vehicles using wireless power transfer. The goal of this thesis is to better understand the economic feasibility, environmental benefit, and infrastructure requirements of a wirelessly charged electric vehicle fleet for transportation in the United States.

Abstract:
Increasing environmental awareness, uncertain economic climates and fluctuating fuel prices have led to airlines investigating the means to lower aircraft fuel burn, emissions and noise, while maintaining the highest possible safety standards. This is done in order to reduce operating costs as well as a desire to offer customers more environmentally responsible transport options. The jet engine has been a fundamental part of passenger aircraft travel and has evolved to become more efficient and quiet. With an aim to improve the overall efficiency of the gas turbine, the industry has consistently sought to improve thermal and propulsive efficiency. Higher thermal efficiencies have been achieved through increased overall pressure ratios and the turbine entry temperatures, while higher propulsive efficiencies has been achieved through increase in bypass ratios. Conventional technology is however reaching the limits of any further improvements. This study seeks to investigate these design limits for the conventional aero gas turbine and focusses on the propulsion system of short to medium range jet aircraft, specifically catering to low cost airline operations in Europe. A techno-economic risk analysis approach was followed through the utilisation of a flexible multi-disciplinary framework. This allows a multitude of critical parameters and factors to be investigated and their effects established. Some of the key parameters investigated include the effect of design optimisation on SFC, mission fuel burn, engine sizes and weights. By first quantifying the current design parameters and associated constraints for the selected conventional propulsion system, an optimisation study is carried out to identify the possible design limits to which the conventional technology may be pushed. It is therefore possible to then quantify the maximum benefit available to this mature technology and also to further identify which future technologies may offer the most benefits for a particular airline market strategy. The key contribution to knowledge from this study is to therefore provide a techno-economic risk assessment of an optimised conventional high bypass ratio turbofan and establish the design limits that may be needed to achieve further benefits from conventional designs. The study is undertaken from an operator/airline perspective and further quantifies the point at which the investment opportunity of a novel technology justifies the risks associated with it. This study has shown that there is still potential for fuel burn improvement from the evolution of the conventional turbofan. This improvement could be up to 15-20% when compared to technology of the year 2000. This is shown to be achieved through improvement material and design of the high pressure compressor spool, aimed at essentially reducing weight and diameters. The study also includes a qualitative discussion on novel, disruptive technologies, and the risks associated with their introduction as future propulsion systems.

The continuous conveying of a solid feedstock like pulverized coal into a pressurized environment is a challenging task required in multiple industrial processes. Plants based on pressurized, entrained-flow gasifiers (EFG) are a good example. EFGs are used to produce synthetic gas for the production of synthetic transportation fuels, chemicals, and for generating electricity in Integrated Gasification Combined Cycle (IGCC) power plants. The latter have also been proposed as an attractive platform for carbon dioxide capture. Commercially available feeding systems are based on coal-water slurry or lock hoppers. The earlier penalizes the plant efficiency and has feedstock limitations, while the latter is expensive and has pressure limitations. In this work, a coupled multiscale approach is applied, which combines system-level analysis, component-level modeling, and micron-scale particle phenomena, for the development and assessment of a novel coal feeding system. The proposed Phase Inversion-based Coal-CO₂ Slurry (PHICCOS) feeding system uses supercritical CO₂ with liquid-like density to feed pulverized coal into a high-pressure EFG. The challenge of preparing the coal-CO₂ slurry is addressed using phase inversion: a phenomenon associated with the hydrophobicity of liquid CO₂-coal mixtures. This allows for operation at ambient temperature and without the use of lock hoppers. Furthermore, the PHICCOS feeding system achieves very high feed pressures while reducing the moisture and ash content of the feedstock, which makes it especially attractive for low-rank and high-ash coal. The merits of the PHICCOS feeding system were demonstrated through technoeconomic analysis coupled with particle-level kinetics. The results of this work show the significant advantages of this system over alternative technologies, in particular for low-rank feedstock. Optimization was used to determine the operating conditions required for the best tradeoff between kinetics, thermodynamics, and costs. The effect of the uncertainty in critical design and operating parameters on the overall economics of a PHICCOS-fed plant were examined using Monte Carlo simulations. This work shows that the PHICCOS system can efficiently and economically feed pulverized coal into high-pressure reactors in plants equipped with carbon capture. Overall, the economics of the PHICCOS feeding system are better than those of commercial technologies for low-rank coal and are competitive with other solutions for high-rank coal. Furthermore, PHICCOS has unique operational advantages related to the very high feed pressures it can achieve and to its feedstock flexibility: cheap and widely available high-moisture and high-ash coal can be used to produce high value products. Keywords: Coal, CCS, Gasification, Feeding System, Multiscale Analysis.

Abstract:
With the accelerated tendency of renewable energy penetration in the electricity grid, energy storage becomes a crucial asset for matching generation and demand. The growth of energy storage systems requires adequate new policies and regulatory frameworks. The battery value chain also requests for new ways of end-of-life management since battery recycling is not a viable single option yet. This is where circular economy offers different solutions and alternatives for prolonging the battery life and reducing the negative impact. This study analyses the technoeconomic feasibility of giving electric-vehicle (EV) batteries a second life as stationary energy storage systems in buildings with integrated on-site renewable energy production, such as for instance PV panels. Four different scenarios have been considered, including the refurbishment of the battery or its direct reuse, taking into account the degradation of capacity and thus, the amortisation price; against the possible load shifting benefit and the reduction of contracted grid power for the building. Results show that, effectively, the reuse of batteries for stationary energy storage is economically justified but may not be worth only in self-consumption applications, that is, for prosumers with some little renewable generation installed on site. The simulations reveal less than 2% relative energy cost savings on annual basis and up to 25% savings related to reduction of grid-contracted peak power, for the chosen case study of a mid-size office building. Second-life battery applications are still dependent on the development of tools for estimating and monitoring the battery’s state of health and potential performance in the new setting, for the technology to succeed. The increasing interest and necessity for circular economy together with the high volume of EV batteries expected to be released on the second-hand market, not suitable for automotive purposes anymore but reasonably applicable for stationary energy storage, will place this topic in the spotlight in the near future.
Den fortsätta trenden för utvidgning av förnybar energi i elnätet gör att energilagring blir en ännu viktigare tillgång för balansen mellan elproduktion och efterfrågan. Nya policyer och regelverk krävs för att understödja en bredare tillämpning av småskaliga energilagringssystem. Batteriets värdekedja kräver också nya sätt att hantera uttömda material eftersom batteriåtervinning ännu inte hunnit utvecklas som ett genomförbart alternativ. En cirkulär ekonomi borde erbjuda olika lösningar inte endast för materialåtervinning utan också gentemot förlängning av livslängden och fördröjning av återvinningsprocessen tills nya metoder och verktyg finns på plats för effektiv hantering med minimal miljöpåverkan. Denna studie analyserar den teknoekonomiska genomförbarheten att ge begagnade batterier från elektriska fordon (EV) en andra tillämpning, typ en utvidgad livslängd, som stationära energilagringssystem för mellanstora kontorsbyggnader med integrerad lokal elproduktion såsom t.ex. solpaneler på taket. Fyra olika scenarier har beaktats, inklusive delvis renovering av batteriet eller dess direkta återanvändning, med hänsyn tagen till kapacitetsnedbrytningen och därmed amorteringspriset, som vägs mot fördelarna i form av en uppnåelig tidsförskjutning av elbehovet och minskning av kontrakterad nätkraft för byggnaden. Resultaten visar att återanvändning av elfordonsbatterier för stationär energilagring är ekonomiskt motiverad men troligen inte alltid värt i applikationer med låg förbrukning och låg egenproduktion av förnyelsebar elkraft. Simuleringarna avslöjar mindre än 2% relativa energikostnadsbesparingar på årsbasis och upp till 25% besparingar relaterade till minskning av nätavtagen toppeffekt för den valda fallstudien av en medelstor kontorsbyggnad. Praktiska tillämpningar av begagnade batterier är fortfarande beroende av utvecklingen av verktyg för uppskattning och övervakning av batteriets hälsotillstånd och potentiella prestanda i den nya installationen, för att konceptet skulle kunna bevisa sitt värde. Det ökande intresset och nödvändigheten för cirkulär ekonomi tillsammans med den stora volymen EV-batterier som förväntas släppas på den begagnade marknaden, inte längre lämpliga för fordonsändamål men rimligt användbara för stationära energilagringssystem, kommer att föra detta ämnesområde in i rampljuset inom en snar framtid.

Abstract:
Over recent years, political, technological, environmental and economic factors have combined to increase interest in distributed energy resources (DER), and flexibility in the power system. As a resource which is both distributed and flexible, flexible demand (FD) can be considered to be particularly of interest. However, due to many facets of its nature, understanding the available flexibility, and potential value of that flexibility, is difficult. Further, understanding the effects of FD exploitation on other multi-energy system actors, given the complex nature of modern liberalised energy systems, complicates the picture further. These factors form material obstructions to the assessment of FD, for example, for the construction of business cases. To address these gaps this thesis first assesses the nature and value of various applicable current and potential markets and charging/incentive regimes, before detailing a novel multi-energy domestic demand simulation model, capable of modelling, in detail, domestic FD resources. Subsequently, a multi-commodity stochastic energy/reserve optimisation model, capable of modelling various DERs and taking into account price signals related to various energy-related commodities and services (including user utility) is specified. The separation of price components for application at different aggregation levels, which is applied in the optimisation model, also informs the described value mapping methodology, which illustrates the impacts of any, particularly demand-side, intervention on the wider multi-energy system. The power of the above detailed contributions are demonstrated through various studies, which show the physical and economic impact of various demand side interventions and of greater market participation by FD resources.

Abstract:
This PhD thesis proposes a bottom-up approach that accurately addresses the operational flexibility embedded in each part of a multi-energy system (MES). Several models which cover the simulations from replicating domestic electrified demands to power system scheduling are proposed. More specifically, a domes-tic multi-energy consumption model is firstly developed to simulate one minute resolution energy profiles of individual dwellings with the installation of prospec-tive technologies (i.e., electric heat pumps (EHPs), electric vehicles (EVs)). After-wards, a fast linear programming (LP) unit commitment (UC) model is devel-oped with the consideration of characteristics of generators and a full set of ancil-lary services (i.e., frequency response and reserves). More importantly, the fre-quency response requirements in low inertia systems are assessed with the con-sideration of three grid frequency regulations (i.e., rate of change of frequency, Nadir and quasi-steady state). Furthermore, the UC model has integrated vari-ous flexibility contributors in MES to provide ancillary and flexibility services, which include pumped hydro storages (PHSs), interconnectors, batteries and demand side resources (i.e., individual EHPs, heat networks, electrolysers). More importantly, the fast frequency response (FFR) provision from nonsynchronous resources is implemented and the demand response application of electrolysers is taken as an example to provide FFR in the UC model. By using the integrated UC model with the consideration of flexibility services provided by resources in the MES, the advantages of multi-energy operation can be clearly identified which can be used to inform system operators and policy makers to design and operate energy systems in a more economic and environment-friendly way.

In this thesis, we have presented a two-stage chemical process synthesis and design for the production of gasoline from glycerin. The study aims to simulate a plant capacity of 90,000 metric tons per year of gasoline. Because glycerin is the co-product from the biodiesel production, we predict that a large quantity of glycerin we can make good use in the future. Starting with 180,000 metric tons per year of glycerin as the raw material, syngas can be produced through the steam reforming process. Then, syngas in turn is converted into the methanol. And by employing purification process, we are able to obtain the methanol production with 99.9 mol% purity. Ultimately, the high-purity methanol is sent to the MtG (methanol to gasoline) reactor and the effluents from the reactor are eventually separated into the desired products by the nature of their different boiling points. Thus, we can achieve the design goal of 90,000 metric tons per year of C5+ gasoline. It should be emphasized that, in this thesis, the glycerin steam reforming reactor and the methanol reactor have both been analyzed via the principle of the chemical engineering thermodynamics. In regard to the distillation columns, we use a “three-step design procedure” to minimize the reboiler’s heat duty and expeditiously save the energy. We specially mention how to use Aspen Plus with “Design Spec/Vary” function to calculate the quantities of natural gas, molten salt and refrigerant used in the process. 　Consequently, we found that 1 kg of glycerin makes 2.8 kg of syngas, 0.6 kg of methanol and 0.52 kg C5+ gasoline. As seen from the engineering economic analysis, we found that we need 0.72 year to recovering the fixed capital cost of manufacture. Since fossil energy ratio (FER) we found is 5.1, this two-stage process from glycerin to gasoline can be regarded as a renewable-energy process. Two kinds of software are utilized in the research—Aspen Plus and CAPCOST. The former is applied to implement the process synthesis and design; the latter is applied to carry out the economic analysis of the project. In sum, we have integrated the theory of the so-called “onion model”, design heuristics, energy integration of heat exchangers and Aspen Plus’ trial-and-error to accomplish the final process results.

Several common ethanol fuel mixtures (E3-E85) are in use around the world. Ethanol fuel mixtures have “E” numbers which describe the percentage of ethanol fuel in the mixture by volume, for example, E3 is 3% anhydrous ethanol and 97% gasoline. Low-ethanol blends, from E5 to E25, are also known as gasohol. At the present moment, the CPC (Taiwan) sells E3 as partial replacements to the more expensive unleaded gasoline in an attempt to reduce CO2 emission. However, it is still far less than E5 to be regarded as gasohol. In this thesis, we have presented a new route to produce ethanol fuel directly from syngas derived from IGCC plants. On the basis of 10,000 tonnes per year of ethanol fuel with purity greater than 99.3 vol%, the engineering economic analysis is also assessed. It should be emphasized that the process design on the reactor system is based on the thermodynamic principles. In regard to the separation system design, we used three different methods to purify the hydrous ethanol. The first is the azeotropic distillation process with cyclohexane as the entrainer, the second is the pressure-swing distillation utilizing two distillation columns that operate at varying pressures and the third is the pervaporation process with hydrophilic membrane. It was found that, among the three purification processes, pervaporation is the most economic one with a yearly manufacture cost of US$9.03 x 106 and a per-liter-cost of the ethanol fuel US$0.76. Three kinds of software are used in the research—Aspen Plus, Aspen Custom Modeler (ACM), and SuperTarget. The first and second are applied to implement the process synthesis and design; the third is applied to perform the pinch analysis and the synthesis of heat exchanger network.

Abstract:
Disposal of sewage sludge, which is a by-product of wastewater treatment, has become one of the greatest challenges of the twenty-first century. Conversion of sewage sludge to a soil amendment can be performed by a broad spectrum of methods, which greatly differ by substrate/amendment composition, treatment time, and physicochemical conditions. The book chapter is focused on (i) environmental and legislative aspects of sewage sludge application in agriculture; (ii) risk factors related to the abundance of pathogens in sewage sludge and methods of SS hygienization; (iii) optimization of the use of SS-derived fertilizers. Application of sewage sludge in combination with mineral fertilizers positively influenced crop growth and soil microbiological activity. An environmental impact of sewage sludge related to its disposal to agricultural areas has been analyzed in terms of global warming, ecotoxicity, and other internationally recognized issues. Narrowly targeted measures may aggravate the situation. Some site-specific factors make sewage sludge unique, hence this specificity must be considered to predict the outcome of its treatment. Determination of these factors remains challenging. Therefore, the complexity of sewage sludge can be reduced by employing integrated biorefinery approaches that will result in circular bioeconomy and industrial ecology solutions.

Abstract:
Within the European research project EnVIronmenTALly Friendly Aero Engines, VITAL, a number of low pressure system component technologies are being investigated. The emerging progress will allow the design of new power plants providing a step change in engine fuel burn and noise. As part of the VITAL project a Technoeconomic and Environmental Risk Assessment tool, the TERA2020, is being developed. Within this tool, means to assess the impact of component technology progress on the engine/aircraft system level has been implemented. Sensitivities relating parameters traditionally used to describe component performance, such as allowable shaft torque, low pressure turbine stage loading, fan blade weight and system level parameters have been established. This allows a direct assessment of the impact of component research progress on the VITAL power plant CO2 and noise emissions.

Abstract:
This paper proposes a preliminary subsonic aircraft and engine noise assessment framework, capable of computing the aircraft total noise level at all three certification points (i.e. Approach, Lateral, and Flyover) defined by the International Civil Aviation Organisation. The proposed framework is numerically integrated to account for the complete aircraft noise sources (i.e. the fuselage, wings, landing gear, as well as noise sources resulting from the engine component level, (i.e. fan, compressor, combustor, turbine, and jet). The developed framework is based on a wide-range of empirical and semi-empirical correlations collected from the public domain literature. The fidelity of the framework also caters for flight effects such as atmospheric attenuation, spherical spreading, Doppler shift, lateral attenuation, retarded time and ground reflection. A conversion between the sound pressure level SPL [SPLdB] to effective perceived noise level EPNL [EPNdB] is also included to allow for a consistent comparison with the certification procedure. Through the successful deployment of the proposed framework a generic aircraft model, representative of a modern commercial carrier aircraft has been investigated, operating under representative operational conditions. The sound pressure level corresponding to various aircraft and engine component have been thoroughly investigated and verified with trends acquired based on the theory. Furthermore, the predictions made by the framework corresponding to the aforementioned three certification points have also been verified against the noise level measurements provided by the International Civil Aviation Organization. The results acquired exhibit good correlation against the verification data for total noise levels at the microphones. Furthermore, a component level comparison is also presented which exhibit good agreement with verification data. The deployed methodology can essentially be regarded as an enabling technology to support the effective and efficient implementation of framework(s) (i.e. Technoeconomic, Environmental and Risk Assessment) targeted to evaluate the existing and advanced aircraft and engine architectures in terms of operational performance and environmental impact.

Abstract:
Procurement of process plant equipment involves decisions based not only on an economic agenda but also on long term plant capability, which in turn depends on equipment reliability. As the greater global community raises environmental concerns and pushes for economic reform, a tool is evermore required for specific and critical selection of plant equipment. Risk assessments based on NASA’s Technology Readiness Level (TRL) scale have been employed in many previous risk models to map technology in terms of risk and reliability. The authors envisage a scale for quantifying technical risk. The focus of this paper is the technical risk assessment of gas turbines as mechanical drivers for producing Liquefied Natural Gas (LNG). This risk assessment is a cornerstone of the TERA philosophy, a Technoeconomic and Environmental Risk Analysis developed by Cranfield University’s Department of Power and Propulsion in the UK. Monte Carlo simulations are used in order to compare the risks of introducing new plant equipment against existing and established plant equipment. Three scenarios are investigated using an 87MW single spool, typical industrial machine; a baseline engine followed by an engine with increased firing temperature and finally an engine with a zero staged compressor. The results suggest that if the baseline engine was to be upgraded then the zero staging option would be a better solution than increasing firing temperature since zero staging gives the lower rise in Total Time to Repair (TTTR), or downtime. The authors suggest a scaling system based on NASA’s TRL but with modified definition criteria for the separate technology readiness levels in order to better relate the scale to gas turbine technology. The intention is to link the modified TRL to downtime, since downtime has been identified as a quantitative measure of technical risk. Latest developments of the modelling are looking at integrating risk analysis and a maintenance cost and scheduling model to provide a platform for total risk assessment. This, coupled with emissions modelling, is set to provide the overall TERA tool for LNG technology selection.

Abstract:
Abstract Saudi Aramco has been a major player in the LPG (Propane and Butane) market since the 1960s and the company continues to be the source of benchmark pricing in the industry. A variety of refrigerated storage tank concepts have been developed to support international export of LPG products. Currently the industry has shifted to the use of safer full containment tank systems which have the capability to contain liquid and vapor release. Economic implementation of new tank systems has the potential of improving safety at company facilities. The benefit of the full containment storage tank is attractive given that the industry is focused on safety and environmental protection. However, the implementation of this technology is challenging due to the cost. Establishing selection criteria is important for economic implementation of any tank type. The paper explores the key design aspects of each type of tank arrangement based on risk assessment, project requirements and economic factors. The paper provides a case study of a current Saudi Aramco project being planned for new installation of LPG storage tanks at a size of one million barrels for both propane and butane services. The risk assessment examined the compliance, business interruption, environmental impact and other factors related to tank containment failures. The risk assessment and technoeconomic study demonstrates that the double steel full containment design is preferred over the prestressed concrete outer container with steel inner container. The double wall steel full containment tank system has been successfully deployed in facilities at sites around the world including at Marcus Hook, PA in the United Sates and Salalah in Oman. Single containment storage tank is not recommended for large scale of LPG storage or when tank is situated with other nearby facilities. Moreover, single containment type requires more plot area due to external diking requirements compared with double wall and full containment storage designs. Optimization of tank type selection may result in reduction of 6 to 8 months in project schedule and savings to the project of up to 70% of the storage tank installation cost. A risk assessment on different storage tanks designs reveals that the double steel wall full containment design is optimal from a cost and schedule prospective.

Abstract:
Abstract Energy is a critical element that is greatly sought after in offshore facilities globally. For remote satellite platforms, oil and gas operators depend on the solar panel to power up their instrumentation and equipment. In certain cases, due to higher power requirements, Mini Turbine Generator (MTG) and Diesel Generator (DEG) are used to satisfy the energy demand of the operation. This paper introduces the Novel Impulse Turbine (NIT) technology for power generation for oil and gas offshore facilities and compares it to the conventional MTG. A techno-economic assessment and comparison for the two technologies are presented, with a case study at a Malaysian gas field. The NIT technology was developed through the extraction of the kinetic energy of the flowing gas and converting it to electrical energy using a novel impulse turbine. The preliminary concept was simulated using process simulation and Computational Fluid Dynamics (CFD) analysis was conducted to refine the critical parameters for prototype fabrication. A 35kW rated prototype was fabricated and tested for Leak Test, No-Load Spin Test, Load Performance Test, Oil System Test. All parameters were within the range of 5% of theoretical values. A two-steps technoeconomic assessment with a case study field was carried out to firm up field implementation. Based on testing and performance analysis carried out, the NIT can perform the rated power output without any combustion process compared to MTG. MTG and NIT have similar footprint requirements and replacing MTG with NIT technology will not yield significant footprint changes. Both MTG and NIT are rotating turbomachinery equipment and have similar maintenance requirements. However, since MTG generates electricity through the combustion of natural gas as fuel while NIT operates based on differential pressure, the latter generates clean energy without the need for fuel combustion. This provides cost savings to the operation as the fuel requirement of MTG increases the operating cost by $10,000 per year. For 20 years of operation, NIT has the lowest life cycle cost due to its advantage of not combusting any fuel to generate electricity. Based on this benchmarking with MTG, NIT provides 15% and 74% of reduction in terms of CAPEX and OPEX respectively. By foregoing the association of generating power with fuel combustion, NIT provides cleaner energy that is in line with global sustainability efforts to reduce greenhouse gases (GHG) such as CO2 and methane.

Abstract:
As a consequence of increased stringent engine emission regulations, in a highly competitive market, it has become necessary to explore innovative, economic and environmentally friendly cycles to sustain competitive advantages. Among these innovative cycles, both the geared and the direct drive counter-rotating open rotors, due to their relatively higher propulsive efficiency, have the potential to significantly reduce fuel consumption and emissions relative to conventional high bypass ratio turbofans. A detailed TERA (Technoeconomic Environmental Risk Analysis), multidisciplinary optimisation framework, can be used to optimise both engines and thereby assess their potential as well as quantify their risks on a formal and consistent basis. This technique is based on detailed and rigorous engine performance, aircraft performance, engine geometry, engine weight, noise, gaseous emissions and environmental impact simulation models. No specific performance simulation methodology for counter rotating open rotors is available in the public domain. An innovative technique is introduced, comprising novel models of: • Counter-rotating propellers (including their interaction); • Counter-rotating turbines; • Planetary differential gearboxes. A thorough description of the modelling methodology (with a justification of the main assumptions) of each of these three components is presented and an indication of work in progress is provided. These components are then used to develop direct drive and geared open rotor performance models. The results of steady state design point and off design performance simulations of these two engine models are subsequently presented via two case studies. Some of the differences in the performance of the low pressure system of geared and direct drive open rotors are highlighted. It was observed that the impact of the key OR performance DP parameters is different for the two engines. Consequently the optimal design and control strategies of theses two configurations will differ. The flexibility of the new simulation technique makes it a suitable candidate to perform multi-disciplinary TERA design space exploration and optimisation studies assess and optimise open rotor designs and control strategies in a multidisciplinary framework.

Abstract:
This paper presents the development of a tool for EnVironmental Assessment (EVA) of novel propulsion cycles implementing the Technoeconomical Environmental and Risk Analysis (TERA) approach. For nearly 3 decades emissions certification and legislation has been mainly focused on the landing and take-off cycle. Exhaust emissions measurements of NOx, CO and unburned hydrocarbons are taken at Sea Level Static (SLS) conditions for 4 different power settings (idle, descent, approach and take-off) and are consecutively used for calculating the total emissions during the ICAO landing and take-off cycle. With the global warming issue becoming ever more important, stringent emissions legislation is soon to follow, focusing on all flight phases of an aircraft. Unfortunately, emissions measurements at altitude are either extremely expensive, as in the case of altitude test facility measurements, or unrealistic, as in the case of direct in flight measurements. Compensating for these difficulties, various existing methods can be used to estimate emissions at altitude from ground measurements. Such methods, however, are of limited help when it comes to assessing novel propulsion cycles or existing engine configurations with no SLS measurements available. The authors are proposing a simple and fast method for the calculation of SLS emissions, mainly implementing ICAO exhaust emissions data, corrections for combustor inlet conditions and technology factors. With the SLS emissions estimated, existing methods may be implemented to calculate emissions at altitude. The tool developed couples emissions predictions and environmental models together with engine and aircraft performance models in order to estimate the total emissions and Global Warming Potential of novel engine designs during all flight phases (i.e. the whole flight cycle). The engine performance module stands in the center of all information exchange. In this study, EVA and the described emissions prediction methodology have been used for the preliminary design analysis of three spool high bypass ratio turbofan engines. The capability of EVA to radically explore the design space available in novel engine configurations, while accounting for fuel burn and global warming potential during the whole flight cycle of an aircraft, is illustrated.
