Economic Feasibility of Soybean Oil Production by Enzyme-Assisted Aqueous Extraction Processing
Food and Bioprocess Technology, 2019Co-Authors: Minghsun Cheng, Kurt A. Rosentrater, Jasreen Sekhon, Tong Wang, Stephanie Jung, Lawrence A. JohnsonAbstract:Aqueous oil extraction is an approach that could replace organic solvent extraction with water. Compared to typical solvent extraction and mechanical pressing processes, aqueous extraction has higher oil recovery (over 80%) than the mechanical pressing process, and resolve issues resulted from chemical loading and remaining in the hexane extraction. Proteases are used to assist free oil release from oil bodies by hydrolyzing cotyledon cell walls in aqueous extraction process. The resulting enzyme-assisted aqueous extraction process (EAEP) includes dehulling, flaking, extruding, enzymatic extraction, and enzymatic demulsification processes. SuperPro Designer was used to conduct a techno-Economic analysis (TEA) of the extraction process. The total capital investment, operation cost, and profits were evaluated. During EAEP, insolubility of water and oil allows the simultaneous extraction of protein and oil. This decreases operation costs, especially the oil purification process, and therefore increases profits made from the main product (soybean oil). This simultaneous extraction also increases the profit towards the coproduct, i.e., protein in skim. Additionally, the absence of chemical and enzyme recycling contribute to the better Economic value of EAEP. Despite the increase in facility costs due to extraction and demulsification units, the value-added coproduct extraction and high free oil yield contribute to the Economic Feasibility of EAEP in industrial- and commercial-scale productions when skim and insoluble fiber are used as water and carbohydrate supplies for integrated soy/corn ethanol biorefinery processing.

Economic Feasibility analysis of soybean oil production by hexane extraction
Industrial Crops and Products, 2017Co-Authors: Minghsun Cheng, Kurt A. RosentraterAbstract:Abstract Hexane extraction is the most common method used in the industry to produce soybean oil due to its high oil recovery and lower production cost. With the demands of soybean oil increasing either in food or industrial applications, expansion plans are considered by many companies to increase production capacity. Techno-Economic analysis is performed to evaluate the Economic Feasibility of soybean oil production by hexane extraction based on historical scenarios from 1980 to 2015. Capital investment, operating costs, revenues, and profits are main parameters to consider when estimating profits, gross margin, return on investment (ROI), and payback time and are the indices used to evaluate the profitability of the process. As the plant capacity increases in scale to over 34.64 million kg of annual soybean oil production, the break-even is met and the producing stream is able to earn profits. Additionally, sensitivity analysis is also applied to examine which factor affects profit the most. In the hexane extraction process, material costs, especially for soybean prices, have the most significant effect on profit. However, soybean meal is the main driving force for soybean oil production due to its significant amount of productivity and revenues.

Economic Feasibility of pipe storage and underground reservoir storage options for power to gas load balancing
Energy Procedia, 2014Co-Authors: Christoph Budny, Reinhard Madlener, Christoph HilgersAbstract:This paper investigates the Economic Feasibility of Power-to-Gas (P2G) systems and gas storage options for both H2 and renewable methane. The study is based on a model-based analysis using the net present value (NPV) method, as well as Monte Carlo simulation for taking fuel and electricity price risks into account. We study three investment cases: a Base Case where the gas is directly sold, a Variant A where temporal arbitrage opportunities between the electricity and gas market are exploited, and a Variant B where the balancing markets (secondary reserve market for electricity, external balancing market for natural gas) are addressed. Centralized and decentralized storage facilities are compared with each other and the optimal type and size determined. In a detailed sensitivity analysis and cost analysis we identify the key factors which could potentially improve the Economic viability of the concepts assessed. We find that P2G for bridging the balancing markets for power and gas cannot be operated profitably. For both temporal arbitrage and balancing energy, pipe storage is preferred. Relatively high feed-in tariffs (100 € MW-1 for H2, 130 € MW-1 for methane) are required to render pipe storage for P2G Economically viable.

The study is based on a techno-Economic model in which the net present value (NPV) method and Monte Carlo simulation of risks and price forward curves for the electricity and the gas market are used. We study three investment cases: a Base Case where the gas is directly sold in the market, a Storage & Arbitrage Case where temporal arbitrage opportunities between the electricity and the gas market are exploited, and a Storage & Balancing Case where the balancing markets (secondary reserve market for electricity, external balancing market for natural gas) are addressed. The optimal type and size of different centralized and decentralized storage facilities are determined and compared with each other. In a detailed sensitivity and cost analysis, we identify the key factors which could potentially improve the Economic viability of the technological concepts assessed. We find that the P2G system used for bridging the balancing markets for power and gas cannot be operated profitably. For both, temporal arbitrage and balancing energy, pipe storage is preferred. Relatively high feed-in tariffs (100 € MW-1 for hydrogen, 130 € MW-1 for methane) are required to render pipe storage for P2G Economically viable.

Effect of electrode covering composition on the microstructure, wear, and Economic Feasibility of Fe-C-Cr manual arc-welded hardfacings
'MDPI AG', 2020Co-Authors: Jankauskas Vytenis, Katinas Egidijus, Laskauskas Artūras, Antonov Maksim, Varanauskas Valentinas, Gedzevičius Irmantas, Aleknevičienė VilijaAbstract:art. n.: 294Manual arc-welded hardfacings are widely used for the protection of new or the restoration of worn parts in agriculture, forestry, and mining applications. A study was conducted to investigate the effect of electrode covering composition on the microstructure, wear (low, average stress abrasion; erosion at 30, 50, and 80 m s−1), and Economic Feasibility of Fe–C–Cr manual arcwelded hardfacings. Hardfacings were produced with the carbon and chrome contents varied in the ranges of 0.87–2.95 and 1.3–33.2 wt.%, respectively. The major phases composing the microstructures of the hardfacings were austenite, perlite, ledeburite, and various carbides, including eutectic M7C3. Technical and Economic analyses were performed to assess the Economic Feasibility of hardfacings and reference wear-resistant steel Hardox 400. A wear and Economic Feasibility map was created to specify various types and facilitate the selection of optimal hardfacings for specific conditions. The produced Fe–C–Cr coatings were the most effective in lowstress abrasive conditions (up to 7.8 times greater than Hardox 400) and quite effective in erosive conditions (up to 2.9 times greater than Hardox 400)Bioekonomikos plėtros fakultetasVilniaus Gedimino technikos universitetasVytauto Didžiojo universitetasŽemės ūkio inžinerijos fakulteta
