ExxonMobil Australia Pty Ltd’s subsidiary, Esso Australia Resources Pty Ltd (ExxonMobil), is undertaking a refurbishment program on the critical combinaire cooling units at its Longford Gas Plant 1. The combinaires are combination air-cooled heat exchangers with evaporative cooling supported on a large concrete structure. The functions performed include gas treating, inlet gas cooling, distillation reflux and condensate cooling.The Longford combinaire units have already been in operation in excess of 30 years and the facility will be required to operate for many more years, given the significant reserves remaining in Gippsland. The combinaire units provide the central cooling duties in both the Longford crude stabilisation plant and Gas Plant 1. Shutdown of these units has a major impact on the plant processing capacity for both oil and gas. An in-depth understanding of forecast market demand, processing requirements and interaction of the process units throughout the Longford facility has enabled the identification of discrete annual periods when certain sections of the combinaire unit can be brought offline.The refurbishment campaign was developed to systematically refurbish sections of the combinaire unit that were not at full capacity seasonally. Critical to achieving the tight timelines is having timely delivery of refurbished and new components to site. This is being achieved through close collaboration with numerous vendors and initiatives such as setting up a local workshop for tube bundle refurbishment.The combinaire refurbishment campaign is on track to meet the target completion date and continues with minimal impact on Bass Strait production of oil and gas. Success is being achieved through detailed analysis across a range of disciplines and the application of a design-one, build-multiple philosophy. A large and complex project being undertaken whilst keeping the plant going.

Esso recently commissioned (October 2017) a new 350-mm 187-km-long pipeline for carrying crude and condensate from Esso’s Longford Plant (Longford) in Gippsland Victoria, along an existing easement to the Long Island Point facility (LIP) at Hastings, Victoria. This pipeline replaces an existing 700-mm pipeline that was approaching the end of its operational life. Through continued delivery of crude and condensate, this pipeline also ensures that the natural gas which is produced along with these liquids continues to flow to Australian households and businesses. The project included pig launching and receiving facilities at Longford and LIP terminals, 10 main-line valve stations as well as fibre-optic cable for control, leak detection and communications purposes. Early engagement of its contractor partners played a key role in the successful execution of the project. Today’s landscape along the pipeline route significantly differs from that when the original pipeline was installed. Individual needs of the landowners affected by the construction were carefully considered. Significant measures were taken to minimise any impact to the unique flora and fauna of the region. Sensitivities around cultural heritage locations were taken into account while finalising the construction methods. Construction of the pipeline occurred in two summer phases (2015–2016 and 2016–2017) to make efficient use of dry weather and to minimise disturbance to landowners and the environment. The project was completed within budget and ahead of schedule.

Esso Australia Ltd (on behalf of the Esso/BHP joint venture) operates a crude oil and natural gas processing system based on the offshore fields in Bass Strait.Crude oil is discharged from the offshore fields via a 132-km pipeline to the crude stabilization plant at Longford. A 187-km pipeline is then used to transfer stabilized crude to Long Island Point, where the oil is held in storage prior to discharge to Australian refineries and to export.Without the use of drag reducer chemical, Bass Strait crude production is limited by pipeline hydraulic capacity. Since the last quarter of 1983, drag reducer has been injected at both Halibut platform and Longford as required to meet the demand for crude oil. As a result, daily production rates have been increased by more than ten per cent.Drag reducer chemical is a long chain polymer which acts to reduce the extent of turbulence in the flowing oil stream. The chemical is highly viscous, and specifically designed gear pumps are required to achieve satisfactory injection into the pipeline systems.

Oat (Avena sativa) is considered as one of the best fodders to mitigate the present seasonal feed deficit for ruminants in Nepal. The study was undertaken to evaluate eleven oat varieties for fodder and seed yield at the Khumaltar condition from December 2021 to April 2022. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. The fodder oat varieties; Ever leaf, Titan, Baler no. 1, Sweet oat, Monida, Qingyin no. 1, Qinghai no. 444, Kona, Swan Pak, Longford, and Netra (as a check variety) were used as the treatments. An experimental unit was a 4 m × 3 m sized plot with the row to row spacing of 0.30 m and continuous sowing within a row. A total of two cuttings were taken for fodder. The observations on growth and yielding characters comprising of plant height, leaf area, number of tillers plant-1, number of leaves/tiller, fodder dry matter, seed and straw yield were recorded. The results showed the fodder dry matter yields ranged from 2.35 to 3.58 t/ha and were not significantly different (p>0.05) among the varieties. The seed and straw yields were obtained statistically different (p<0.05) among the varieties. Netra (2.90 t/ha) and Kona (2.88 t/ha) produced higher seed yields. Similarly, the highest straw yield was produced for the variety Longford (8.73 t/ha).

On behalf of itself and BHP-B, Esso operates offshore production platforms in Bass Strait, a crude stabilisation and gas processing plant at Longford and a LPG fractionation plant at Long Island Point, Victoria. The Technical Surveillance Program for these facilities is implemented at both the Operator and Engineering levels. The program has been enhanced by building on existing DCS process control and process information (PI) systems and through development of a more structured engineering monitoring system. The enhanced program continues to register tangible benefits in integrity, product quality, recovery, efficiency and reliability and capacity.At the operator level, the process is monitored continuously, assisted by process alarms to maintain the plant within the normal desirable operating zone. Safe operating limits define the outside boundary of the safe operating envelope which is secured with shutdown and other automatic protective devices. Alarm and limit conditions associated with these parameters have been incorporated into the DCS control system with pre-defined operator responses appearing automatically on the screen if the condition is reached.At the engineering level, the surveillance program is a systematic periodic monitoring process focussing on optimum performance and continuous improvement. It is structured using the elements of a management system. Within this framework, engineering spreadsheets have been developed with direct links to process data via process information system software. The spreadsheets assist plant engineers to efficiently monitor the key performance variables; they also pre-define the acceptable operating range, calculate statistical performance, highlight deviations and hyperlink back to the PI system for more detailed troubleshooting. Day-today deviations and performance improvements are fed back and reviewed at the working level, more significant issues are formally investigated and reviewed with management. Key data and overall performance is summarised monthly, and formally reviewed by plant and engineering management.

Food processing effluents often contain high levels of nutrients, particularly N. Conventionally, anaerobic ponds are used to purify these effluents in Australia, giving cost-effective removal of BOD but little nutrient removal. It has become apparent that disposal by irrigation as presently practised normally exceeds sustainable N application rates, thus reduction of nutrient levels before irrigation is becoming mandatory. Meatworks effluent is often discharged to country town sewers, frequently accounting for 50-75% of the nutrient load. Meatworks effluents contain 1,000-4,000 mg/L BOD, 200-400 mg/L TKN and 20-50 mg/L P. Conventional BNR technology can readily remove nutrients from such effluents, either alone or in combination with anaerobic ponds but sludge handling on such a small scale poses economic problems. Laboratory scale trials showed that both BOD removal from meatworks effluent and sludge disposal could be achieved readily in conventional anaerobic ponds. The pond effluent, together with the town sewage if required, could be treated in a sequencing batch reactor (SBR) designed for nitrification/denitrification service. Optimisation of the anaerobic pond operation was required to ensure production of the minimum BOD:N ratio needed for N removal. This paper will describe the design and commissioning of two plants; a demonstration plant installed at a typical sized meatworks in Gippsland, Victoria, and a full scale plant for treatment of combined domestic sewage and effluent from a large meatworks at Longford, Tasmania. In neither case (for different reasons) has P removal yet been required. It was demonstrated that 98% of BOD and up to 95% N removal may be cheaply and readily achieved in the SBR. Where lagoons are used, levels of N suitable for river discharge can be achieved. P can be readily removed by alum treatment when required.

Esso Australia Resources Pty Ltd and BHP Petroleum (Bass Strait) Pty Ltd own a range of offshore and onshore hydrocarbon production facilities, which have been operated by Esso Australia Pty Ltd (Esso) for over 50 years. The Longford Fire Training Ground (FTG) is located adjacent to the Longford Plants and has been utilised by Esso for many years to train personnel in practical hydrocarbon firefighting skills, including applying firefighting foams to extinguish liquid hydrocarbon pool fires. In line with historical standard oil-field practices, per and polyfluoroalkyl substance (PFAS) containing firefighting foams were used at the Longford FTG. In response to the reported use of these foams and the potential for contamination associated with historical site operations, the Longford premises were the subject of recent environmental audit and clean-up plans with oversight by an EPA Victoria auditor. Esso engaged a broad range of experts to complete the environmental investigation and develop a remediation action plan that complied with the PFAS National Environmental Management Plan. Key aspects of this project included: understanding the location and setting, with respect to geological conditions and groundwater impacts; development of remediation objectives and strategy; identification of practical remediation methods including short-term and longer-term measures to mitigate priority PFAS sources within the FTG; and a planning framework for future management of the premises. This paper shares how a responsible operator applies a disciplined and scientifically based environmental approach to further the state of knowledge on practical PFAS remediation methods and achieve a sustainable environmental outcome in the communities that they operate in.
