This study has been performed to determine the technical and economic feasibility of employing hypersorption process technology to separate and purify a medium - Btu gas, derived from oxygen-blown gasifiers, to obtain a H/sub 2//CO ratio of 2:1 as a feed to a Fischer-Tropsch type plant. Technical feasibility is a measure of the ability to design a hypersorption separation and purification process from available data. Economic feasibility can be made through comparisons with commercially available process technology. Three gasification processes have been used as a basis for this study. These processes are based upon EPRI Report AF-244 for the Lurgi moving bed, oxygen-blown, dry bottom gasifier, and EPRI Report AF-642 for the Texaco, slurry fed, oxygen-blown, entrained bed gasifier and for the Foster-Wheeler, oxygen-blown, entrained bed gasifier. Process designs for the hypersorption separation and purification for each case have been made using engineering judgments based on the available adsorption isotherms, which have been obtained from the Calgon Corporation. No attempt has been made to optimize these designs although some additional studies have been done where it has been deemed desirable. Cryogenic separation and acid gas purification for each case have been supplied by Lotepro as a packaged unit. Economic evaluations are ambiguous. All plant investments are within the +- 30% accuracy of this study. No clear cut choice between cryogenic separation - acid gas purification and hypersorptive separation - purification can be made based on plant investment. Operating costs are within the +- 30% accuracy. However, in the Foster-Wheeler case the operating costs are 28% greater for the hypersorption process. 12 figures, 42 tables.
