Therefore, if this process is redesigned, it is recommended to design a process that requires less air flow or a lower pressure. The CAPCOST spreadsheet software (Turton et al., 2009) was used in estimating capital costs of equipment, otherwise referred as fixed capital investment (FCI). The main utility cost originates from the cost of compressing the large amount of air flowing through the system. Although the maleic anhydride product is more profitable than the feed stream, the high annual utility cost of $39,100,000 causes a negative net present value for this process. It is recommended, based on the profitability analysis, that this process not be pursued further. The desired solid maleic anhydride is purified using a series of cyclones. Maleic anhydride and several byproducts are produced from this reaction.
This pure stream is mixed with oxygen in air and fed to the reactor. The process begins by feeding the mixed butane stream through two distillation columns to achieve pure n-butane. A catalyst, vanadium phosphorous oxide, assists in this reaction, adsorbing oxygen onto its surface to enable its reaction with n‑butane. Maleic anhydride is produced by the thermal oxidation of n-butane at an elevated temperature and pressure, in this case 375☌ and 20 bar.
The simulation software Aspen Plus by AspenTech was the primary software used to design the plant, and the CAPCOST program in Microsoft suite’s Excel was utilized for the economic review of the process.
software and Aspen Process Economic Analyzer is that, unlike CAPCOST. Meyers, editor, McGraw-Hill (2005), 665.538 H236. Chemical process simulators are software tools developed to mimic the behavior. (search plant costs, chemical prices, Nelson-Farrar refinery construction index, refinery operating costs) Handbook of Petrochemicals Production Processes, Robert A. As with any newly developed technology, researchers must take care to address all concerns, limitations, and dangers before widespread public adoption. Includes capital costs for several plants, equations for some equipment, etc.
This design team has been asked to produce a conceptual design, simulation, and profitability analysis for the proposed plant. Capcost Software - From driverless cars to vehicular networks, recent technological advances are being employed to increase road safety and improve driver satisfaction. and proven systems of equations were used in the CAPCOST DSS software to. the latest version of capcost (capcost2017.xlsm) is a microsoft excel macro-enabled file that allows the calculation of equipment costs, total plant cost, cost of manufacturing (comd), cash flow analysis, and monte carlo simulations of cash flows. The plant is to produce 40,000 metric tons per year of maleic anhydride from a mixture of excess butanes. CAPCOST estimated gas explosion losses periences based on human behavior and. Gamecock Chemical Company has proposed the construction of a maleic anhydride plant at its Houston refinery.
