The drying process is a step of ceramic brick production which requires the control of process variables to provide a final product with a porous uniform structure, reducing superficial and volumetric defects and production costs. Computational fluid dynamics (CFD) is an important tool in this process control, predicting the drying physical phenomenon and providing data that improve the industrial efficiency production. Furthermore, research involving CFD brick drying has neglected the effects of oven parameters, limiting the analysis only to the bricks. In this sense, the aim of this work is to numerically study the hot air-drying process of an industrial hollow ceramic brick in an oven at 70 °C. The results of the water mass and temperature distributions inside the brick, as well as moisture, temperature, velocity and pressure fields of the oven drying air at different process times are shown, analyzed and compared with experimental data, presenting a good agreement.

The purpose of this paper is to present an experimental study of clay brick drying. For the drying experiments, industrial holed bricks were dried in an oven under controlled conditions of velocity, temperature (constant and variable) and relative humidity of air. The continuous drying experiments ended when the mass reached constant weight. Experimental tests were performed under atmospheric pressure. Results of the drying and heating kinetics and volume variations during the process are shown and analyzed. It was verified that the drying process happens in the falling drying rate period, and air temperature has large influence in the drying rate during process. It was verified that the largest temperature, moisture content and stress gradients are located in the vertexes of the brick.

Quality characteristics of 30 commercial wheat flour samples from Czech industrial mills and 30 wheat flour samples prepared from wheat varieties cultivated in experimental fields (all from wheat harvest 2000) were analysed in detail including maturograph and spring oven (both from Brabender, Germany) as well as bread baking test (Czech method). Specific bread volumes of all flour samples were compared with the bread volumes determined by the oven spring test. The correlation analysis which expressed the relations between wheat flour rheological characteristics and the bread volume is reported. The maturograph parameters correlate significantly with the specific bread volume and the final volume obtained by means of oven spring. All the correlations with the baking test values are high. Both instruments used are suitable for the prediction of the flour baking quality.

Industrial wastewaters with high ammonia concentrations, high toxicity and/or unfavourable COD/N ratio call for special attention and concern with regard to design and operation of the wastewater treatment system. Two cases are described: wastewater from a rendering plant and from a coke oven plant. The precondition for obtaining and maintaining a nitrification process in both a rendering plant and a coke oven plant is close control and regulation of pH in the process tanks. Both high and low values of pH cause inhibition of the nitrifiers. pH should be kept in the range 6.5-7.0. The organic fraction at the rendering plant mainly consists of easily biodegradable organic acids. The BIO-DENITRO concept has been chosen for this application and proven to be very efficient to obtain low effluent values for (NH3 + NH4)-N due to the flexibility in adjusting the phase length under variation in loadings and wastewater composition. Complete denitrification could be obtained with COD/N ratio larger than 5. Wastewater from a coke oven plant contains compounds that are extremely toxic to the nitrifiers as for example phenol, cyanide, thiocyanate, sulphide and ammonia. Sufficient upstream buffering is essential to prevent shock loads. In order to obtain complete denitrification at the coke oven plant by using an internal carbon source, it is necessary to have an efficient ammonia stripping and phenol must not be removed from wastewater. COD/N ratio must be larger than 8 to obtain complete denitrification.

In a steel plant, fuel gas caloricity of ignition oven always changes rapidly and largely. Consequently, the temperature of ignition oven can’t keep steady. To overcome this problem we employ intelligent control of ignition oven based on PIDNN (Proportional-Integral-Derivative Neural Network). As we know, ignition oven is a nonlinear, large delay and slow time-varying process, so traditional PID control usually doesn’t work well. Artificial neural networks can perform adaptive control by learning, so we adopt Proportional-Integral-Derivative neural network to tackle the problem taking the advantages of both PID control and neural structure. In order to satisfy the restrictions of industrial instruments, we combine PIDNN control algorithm with expert system mechanism to fulfill the final intelligent control strategy. At a sintering plant in Hangzhou, we deploy the intelligent control strategy turning out a satisfactory result that the ignition oven temperature can be controlled steadily within a much smaller range with significant saving of labor costs and improving of energy efficiency.

In bread-making, the baking process is one of the key steps to produce the final product quality attributes including texture, color and flavor, as a result of several thermal reactions such as non-enzymatic browning reaction, starch gelatinisation and protein denaturation. These thermal reactions are dominated by heat and mass transfer mechanisms inside an oven chamber as well as inside the dough pieces. In this study, an industrial baking process was divided into 4 zones. Experiments were conducted, and mathematical models were developed to account for the heat and mass contribution as well as their consequent impacts on the product qualities. Monitoring systems were developed and installed inside an industrial oven to evaluate oven performance, including temperature profile and airflow pattern. Many other tests and experiments were conducted and results given in some detail. To deal with the complexity of a continuous baking process, a three dimensional transient-state CFD model with moving grids was established to account for the effect of oven load on heat transfer in the oven chamber. The dynamic response of the travelling tin temperature profiles could be predicted in accordance with a change in the oven load. The modelled tin temperature profiles showed a good agreement with the measured tin temperature profiles from the actual industrial baking process. Finally, the three-dimensional CFD model could provide guidance in manipulating the oven condition to achieve the optimum temperature profile in the industrial travelling-tray baking oven.

This thesis presents a study of the cooling process of a solid block performed by a turbulent air flow channel. The study focuses on the turbulent flow and its influence in the heat transfer of the block.

The first part of the thesis is an analysis of the different turbulent model and their adaptation on the necessities of this study. Once the turbulent model has been confirmed it makes a study of the behavior of the cooling process by CFD (Computational Fluid Dynamics), and an analysis of the numerical accuracy of this computational study.

When the procedure of the study of the cooling process is defined it proposes some different variations in the initial solution to improve this process. The study concentrates in variations of the turbulence and the geometry of the studied block.

Finally, the different improving are discussed analyzing parameters as the heat transfer, pressure drop, time consuming or energy consuming.

Particularly in Braziland in Rio Grande do Norte, companies manufacturing red ceramic, play an important role as agents of development to study the region Serid?- RN, specific place for carrying out the research. It is observed in this region a concentration of red ceramic industries of small size, which, despite its importance in the ceramic, they are unable to enjoy or use the new forms of administrative management and technological advances designed and offered by universities, centers of research and projects of governments, remained almost entirely outside the progress and modernization, technological and administrative. These companies still have outdated technology, and management processes, providing quality problems and standardization of end products. Upon these conditions are the companies going through crisis and struggling to survive alone and without assistance. The region of Serid?-RN, lets make a detailed case study of red ceramic companies in the region proposed from the existing theoretical and actual lifting of the condition of the product manufacturing red ceramic, allowing through this overview of the implementation of collect samples of raw materials, allowing the study of each ceramic industry that contributed to the participation of the research, which was determined parameters such as: analysis of the physical, chemical and technological properties of raw materials, characterization of the processes used, raising the technological resources considering equipment, machinery, supplies, raw materials and facilities available and its organization by type of products from companies involved in this study. The methodology consists of the following steps: collection of raw material, crushing and screening, characterization of raw materials (liquid limit, chemical analysis, mineralogical analysis, differential thermal analysis, sieve analysis), mixing, forming, cutting, drying and burning of ceramic bodies and bodies of evidence. The results showed that it was clay with distinct characteristics with respect to plasticity. With respect to the different compositions of mixtures of ceramic masses, we conclude that the ceramic properties showed a direct proportionality with increasing fraction of the clay not plastic. However, the compositions of the masses studied proved to be the most appropriate for the types of simulated clay for use in ceramics. Adopted in the ceramic processing made it possible to obtain products the resulted in consistent properties, and in some cases even exceeding the requirements of technical studies and standard-Brazilian clays to obtain ceramic products such as tiles, bricks and tiles to floor. Based on the discussions from the results obtained in the various processing steps of this work, one can draw conclusions according to the physico-chemical and mineralogical properties of raw materials, the properties of ceramic products burned and analysis. This work may be used by other researchers, private companies and governmental organizations, undergraduate students and graduate, can develop studies and future research to: develop projects to modify the furnaces; mapping projects develop and rationalize the exploitation of raw materials ;promoting reforestation and forest management; develop reduction projects and recovery of waste; develop training projects in manpower sector, and develop security projects, improving the conditions of work in the area pottery
No Brasil e particularmente no Estado do Rio Grande do Norte, as empresas de fabrica??o de cer?mica vermelha, representam um papel importante como agentes de desenvolvimento de estudo para a regi?o do Serid?-RN, local determinado para a realiza??o das pesquisas. Observa-se nesta regi?o uma concentra??o de ind?strias de cer?mica vermelha de pequeno porte, que, apesar de sua import?ncia no contexto cer?mico, estas n?o conseguem usufruir ou utilizar as novas formas de gerenciamento administrativo e de avan?os tecnol?gicos concebidos e propostos pelas Universidades, centros de pesquisas, bem como dos projetos dos Governos, permanecendo na sua quase totalidade ? margem dos avan?os e da moderniza??o, tanto tecnol?gico como administrativo. Estas empresas apresentam ainda processos tecnol?gicos e gerenciamentos ultrapassados, propiciando problemas de qualidade final e padroniza??o de seus produtos. Mediante estas condi??es ficam as empresas atravessando crises e lutando para sobreviverem isoladas e sem assist?ncia. A regi?o do Serid?-RN, permite efetuar um estudo de caso detalhado das empresas de cer?mica vermelha na regi?o proposta, a partir do referencial te?rico existente e do levantamento real da condi??o de fabrica??o do produto cer?mico vermelho, possibilitando atrav?s deste panorama geral a realiza??o da coleta de amostras de mat?rias primas, permitindo o estudo de cada ind?stria cer?mica vermelha que contribuiu na participa??o da pesquisa, onde foi determinado par?metros tais como: an?lise das propriedades f?sicas, qu?micas e tecnol?gicas das mat?rias primas, caracteriza??o dos processos utilizados, levantamento dos recursos tecnol?gicos considerando equipamentos, m?quinas, insumos, mat?rias primas e instala??es dispon?veis e a organiza??o dos mesmos por tipologia de produtos das empresas envolvidas neste estudo. A metodologia aplicada consta das seguintes etapas: coleta da mat?ria prima, moagem e peneiramento, caracteriza??o das mat?rias-primas (limite de liquidez, an?lise qu?mica, an?lise mineral?gica, an?lise t?rmica diferencial, an?lise granulom?trica), mistura, conforma??o, corte, secagem e queima das massas cer?micas e nos corpos de prova. Os resultados obtidos revelaram tratar-se de argilas com caracter?sticas distintas com rela??o ? plasticidade. Com rela??o ?s diversas composi??es das misturas das massas argilosas, conclu?mos que as propriedades cer?micas apresentaram uma rela??o direta de proporcionalidade com o aumento da fra??o da argila n?o pl?stica. No entanto, as composi??es das massas estudadas mostraram-se as mais adequadas para os tipos de argilas simuladas para aplica??o em cer?mica. No processamento cer?mico adotado, possibilitou obterem-se produtos que resultaram em propriedades compat?veis e, em alguns casos, at? superiores as exig?ncias das normas t?cnicas e estudos de argilas padr?o-brasileiras para a obten??o de produtos de cer?mica, tais como, telha, tijolos e lajotas para piso. Tendo como base ?s discuss?es realizadas a partir dos resultados obtidos nas diversas etapas de processamento deste trabalho, podem-se elaborar conclus?es de acordo com as caracter?sticas f?sico-qu?micas e mineral?gicas das mat?rias-primas, das propriedades cer?micas dos produtos queimados e das an?lises.

Resumo: Caldeiras de produção de vapor são utilizadas no setor siderúrgico para produzir e disponibilizar vapor para o processo de geração de energia e para os vários setores que necessitam de aquecimento durante a fabricação de seus produtos, como por exemplo, a vaporização de criogênicos para distribuição na planta. Portanto, caldeiras são equipamentos que necessitam ter confiabilidade. Atualmente, a CSN (siderúrgica brasileira de grande porte) possui duas caldeiras do início da década de 80 que somente partem e operam com uma chama piloto utilizando gás de coqueria, um gás que é subproduto da produção de coque em uma planta siderúrgica. Assim, para alcançar o objetivo de mais confiabilidade e flexibilidade na operação destas caldeiras, utilizou-se os métodos de índice Wobbe, corrigido pela pressão, e o método dos múltiplos índices de Weaver para avaliar a substituição do gás de coqueria pelo gás natural de modo que estas caldeiras possam operar com gás natural em caso de indisponibilidade de gás de coqueria. Mesmo que o aporte energético entre os gases seja diferente, este pode ser ajustado pela pressão do gás. A temperatura de chama adiabática não tem variação significativa, reduzindo-se apenas 1,4%. As emissões de fumaças e CO2 aumentam com a substituição, porém as emissões de NOx tem redução. A utilização do método dos múltiplos índices de Weaver para análise de intercambiabilidade demonstra que o gás natural não é um substituo para um queimador projetado para queimar gás de co...

Abstract: Steam generators are used in the steel industry to produce and supply steam process for power generation and for other sectors that need heat to manufacture their products, such as the cryogenics vaporization for distribution in the facilities. Therefore, steam generators are equipment that need to have reliability. Currently, CSN (large Brazilian steelmaker) has two steam generators from the early 1980s that only startup and operate with a pilot flame using coke oven gas, a gas that is a byproduct of coke production at a steel plant. Thus, in order to achieve the working objective, reliability and flexibility in the operation of these steam generators, the Wobbe index method, with pressure-corrected, and the Weaver's multiple index method were used to verify the coke oven replacement for natural gas, and then, these steam generators can operate with natural gas in case of coke oven gas unavailability. Results shown in the same way that the energy increase between the gases are different can be adjusted in the pressure reduction. The flame temperature has insignificant variation, only 1.4%. Off gas and CO2 emissions increase with interchangeability. However, NOx emissions are reduced. The Weaver multiple index method for interchangeability analysis demonstrates that natural gas is not a gas to replace coke oven gas in a burner designed to burn coke oven gas, but if the burner is designed to natural gas, coke oven gas may be the substitute gas. Regarding the heat input and pri... (Complete abstract click electronic access below)

This research is aimed at improving low-grade industrial ovens (less than 250°C) in the manufacturing industry. Industrial ovens have a significant bearing on the environmental and economic impacts of a manufacturing factory due to their excessive fossil fuel consumption and influence on product quality. Therefore, this thesis’ research question is: 'How can manufacturers improve the environmental and economic performance of industrial ovens?' Research on industrial oven improvement is under-developed and there are significant improvement opportunities within many industrial-heating processes. Manufacturers traditionally prioritise economic assessment when evaluating capital investment projects and it is important that systematic engineering of industrial ovens align energy saving and process enhancement with key business interests. Furthermore, there is a need to incorporate stakeholder perspectives when improving oven processes. This thesis consists of three bodies of research, which all develop ways to improve the environmental and economic performance of industrial ovens: 1) Energy saving through process optimisation, 2) Process enhancement considering both energy consumption and product quality, 3) Developing sustainable industrial ovens. The key research outputs from this thesis are shown below: • There are two options to reduce energy consumption; to optimise the process by changing parameters, or to innovate the process by changing the way the heat is supplied to an oven. • System airflow can often be reduced by up to 30%. This was demonstrated at two factories and three oven systems, and has reduced gas energy consumption by 4,536,000 kWh and cut carbon emissions by 836 tCO2e per year. This has delivered a combined annual cost saving of £121,000. • Installing sufficient control capability enables heating processes to be optimised throughout their life, to meet changing requirements. • A novel approach of polymer cure characterisation has been developed that combines DMTA and a free phenol/CIE-Lch test. This demonstrated that temperature variation within a festoon oven results in dramatically different cure conversion (complete conversion time ranges from 73 to 40 minutes depending on location) and product quality. • A novel multi-criteria analysis method incorporating sustainability indicators from stakeholder’s perspectives has been developed for oven optimisation. • Retrofitting gas-fuelled processes with biomass technology is not economically viable. Alternative schemes that negate capital cost from the business would significantly enhance biomass viability. • Biomass technology is more viable in newly-built processes than retrofit scenarios. • EU Emission Trading Scheme (ETS) is an effective tool to encourage uptake of biomass heating technology in the manufacturing industry. This study demonstrates that there is opportunity to improve low-grade heating processes in the manufacturing industry. The environmental and economic performance of industrial ovens can, and should, be improved to help the manufacturing industry move towards a more sustainable future.

En s'appuyant sur une connaissance précise du temps, sur la réservation de ressources et l'application distribuée de règles d'admission strictes, un réseau déterministe permet de transporter des flux pré-spécifiés avec un taux de perte extrêmement bas et une latence maximale majorée, ouvrant la voie au support d'applications critiques et/ou temps-réel sur une infrastructure de réseau convergée. De nos jours, la Technologie Opérationnelle (OT) s'appuie sur des réseaux déterministes mais conçus à façon, en général propriétaires, utilisant typiquement des liens série spécifiques, et opérés en isolation les uns des autres, ce qui multiplie la complexité physique et les coûts d'achat et de déploiement (CAPEX), ainsi que d'opération et maintenance (OPEX), et empêche l'utilisation agile des ressources. En apportant le déterminisme dans les réseaux des Technologies de l'Information (IT), une nouvelle génération de réseaux commutés de l'IT va permettre l'émulation de ces liens série et la convergence de réseaux autrefois dédiés sur une infrastructure commune à base d'IP. En retour, la convergence de l'IT et de l'OT permettra de nouvelles optimisations industrielles, en introduisant des technologies héritées de l'IT, comme le BigData et la virtualisation des fonctions du réseau (NFV), en support des opérations de l'OT, améliorant les rendements tout en apportant une réduction supplémentaire des coûts. Les solutions de réseaux déterministes réclament des possibilités nouvelles de la part des équipements, possibilités qui vont bien au-delà de celles demandées pour les besoins classiques de la QoS. Les attributs-clé sont : - la synchronisation précise de tous les n'uds, en incluant souvent la source et la destination des flux- le calcul centralisé de chemins de bout en bout à l'échelle du réseau- de nouveaux filtres de mise en forme du trafic à l'intérieur comme à l'entrée du réseau afin de le protéger en tous points- des moyens matériels permettant l'accès au medium à des échéances précises. Au travers de multiples papiers, de contributions à des standards, et de publication de propriété industrielle, le travail présenté ici repousse les limites des réseaux industriels sans fils en offrant : 1.

Based on time, resource reservation, and policy enforcement by distributed shapers, Deterministic Networking provides the capability to carry specified unicast or multicast data streams for real-time applications with extremely low data loss rates and bounded latency, so as to support time-sensitive and mission-critical applications on a converged enterprise infrastructure.As of today, deterministic Operational Technology (OT) networks are purpose-built, mostly proprietary, typically using serial point-to-point wires, and operated as physically separate networks, which multiplies the complexity of the physical layout and the operational (OPEX) and capital (CAPEX) expenditures, while preventing the agile reuse of the compute and network resources.Bringing determinism in Information Technology (IT) networks will enable the emulation of those legacy serial wires over IT fabrics and the convergence of mission-specific OT networks onto IP. The IT/OT convergence onto Deterministic Networks will in turn enable new process optimization by introducing IT capabilities, such as the Big Data and the network functions virtualization (NFV), improving OT processes while further reducing the associated OPEX.Deterministic Networking Solutions and application use-cases require capabilities of the converged network that is beyond existing QOS mechanisms.Key attributes of Deterministic Networking are: - Time synchronization on all the nodes, often including source and destination - The centralized computation of network-wide deterministic paths - New traffic shapers within and at the edge to protect the network- Hardware for scheduled access to the media.Through multiple papers, standard contribution and Intellectual Property publication, the presented work pushes the limits of wireless industrial standards by providing: 1. Complex Track computation based on a novel ARC technology 2. Complex Track signaling and traceability, extending the IETF BIER-TE technology 3. Replication, Retry and Duplicate Elimination along the Track 4. Scheduled runtime enabling highly reliable delivery within bounded time 5. Mix of IPv6 best effort traffic and deterministic flows within a shared 6TiSCH mesh structureThis manuscript presents enhancements to existing low power wireless networks (LoWPAN) such as Zigbee, WirelessHART¿and ISA100.11a to provide those new benefits to wireless OT networks. It was implemented on open-source software and hardware, and evaluated against classical IEEE Std. 802.15.4 and 802.15.4 TSCH radio meshes. This manuscript presents and discusses the experimental results; the experiments show that the proposed technology can guarantee continuous high levels of timely delivery in the face of adverse events such as device loss and transient radio link down

In recent years, scholars from a range of disciplines have analyzed the collective set of federal R&D programs as a high tech-oriented industrial policy through which the US government actively targets certain economic sectors over others for state support. Analysts have emphasized one dominant institutional feature of this system: federal R&D programs lack a central planning mechanism, and are instead highly fragmented and ad hoc. While some analysts have interpreted this institutional structure as a strength, others view the absence of R&D planning as a major shortcoming, a view shared by policymakers advocating for increased coordination of federal R&D programs in order to help combat economic and environmental challenges. This study examines the origins and institutional evolution of federal innovation policy, and in doing so, probes possibilities for future reform. My account focuses primarily on the business-state nexus as an explanatory factor, emphasizing the role of politically active industrial firms in shaping the system's legal and institutional structure. I argue that R&D-based industrial firms were opposed to proposals for R&D planning, but only insofar as these proposals also threatened a separate institutional feature to which these firms were more firmly committed: the transfer of patent rights resulting from government-led R&D projects into private hands. During the New Deal and into the immediate postwar period, the link between patent reform and innovation planning prompted industrial firms to lead the attack against progressive calls for a more coordinated R&D system. When government patent policy became decoupled from planning during the Space Race and eventually led to a new consensus on "technology transfer," industrial firms shifted in favor of R&D planning but by that time saw their political influence substantially reduced. The neoliberal business coalition lobbied instead for increasingly fragmented one-off programs to promote specific high-tech fields--a "hidden developmental state" that would remain intact until the present. From this perspective, the structure of the federal R&D system is more a result of a conflict over property than over planning, and the institutional link between coordination and government patent policy may frustrate future attempts to finally realize planned innovation in the US.

AbstractIn the constant evolution of industrial systems, there is currently a strong trend towards Time-Sensitive Networking (TSN). This trend corresponds with the upcoming requirements of integration and flexibility in the Smart Factories and the fusion of Information Technology (IT) and Operational Technology (OT). However, industrial environments using legacy communication are still used in existing shop floors. One example to implement redundant interconnections and communication via heterogeneous networks is presented here using the CANopen Flying Master technology and a TSN backbone.

Resumo:
The baking industry is considered as one of the major energy consuming food industries in North America. More than 40% of bakery fuel consumption is used to evaporate water in the processes [1]. In addition to the baking process’ vapor the oven stack gas contains water vapor from combustion products. Overall the content of water vapor in the typical oven stack gas is about 20% by volume. Most bakeries waste this vapor and its latent heat. Bakeries’ ovens have wide diversity in power and design. Off-the-shelve heat exchangers are not considered as cost effective equipment for stack gas cooling below gas’ dew point temperature. At typical oven stack gas composition water vapor condensation begins to condense at about 72° C. Not using the latent heat of stack water vapor and the heat from gas cooling from dew point temperature to ambient temperature results in low effectiveness of waste heat recovery. Mainly the effect from the recovery of stack gas cooling prior to condensation is considered as non cost effective and waste heat recovery is neglected.

The objective of this study is to investigate Saudi Arabia’s industrial electricity consumption at the regional level. We apply structural time series modeling to annual data over the period of 1990 to 2019. In addition to estimating the size and significance of the price and income elasticities for regional industrial electricity demand, this study projects regional industrial electricity demand up to 2030. This is done using estimated equations and assuming different future values for price and income. The results show that the long-run income and price elasticities of industrial electricity demand vary across regions. The underlying energy demand trend analysis indicates some efficiency improvements in industrial electricity consumption patterns in all regions.

There is a high degree of freedom and flexibility in the way to integrate renewable process heat in industrial processes. Nearly in every industrial or commercial application various heat sinks can be found, which are suitable to be supplied by renewable heat, e.g. from solar thermal, heat pumps, biomass or others. But in contrast to conventional fossil fuel powered heating systems, most renewable heating technologies are more sensitive to the requirements defined by the specific demand of the industrial company. Fossil fuel-based systems benefit from their indifference to process temperatures in terms of energy efficiency, their flexibility with respect to part-load as well as on-off operation, and the fuel as a (unlimited) chemical storage. In contrast, the required temperature and the temporal course of the heat demand over the year determine whether a certain regenerative heat generator is technically feasible at all or at least significantly influence parameters like efficiency or coverage rate.

Resumo:
Utah’s abundant energy and mineral resources are used to heat homes, drive industry, and keep the lights on. Effectively managing these energy and mineral resources and their associated supply chains requires knowledge of their economic value and how they currently contribute to Utah’s economy. This report calculates the total economic contribution of Utah’s energy and mining industries for 2019 and 2020. Each industry makes substantial contributions to Utah’s gross domestic product, employment, and tax base. Collectively, these industries contributed over 10% to Utah's total Gross Domestic Product (GDP), supported over 7% of its jobs, and contributed 20% to state tax revenue. Not only do these industries produce sizable economic value, they also create high-paying jobs. Average wages for the energy and mining industries were calculated to be $22,415 (45%) and $13,652 (28%) above the overall state average wage, respectively.
