The objective of this program is to recommend the most attractive combinations of acid gas removal and cryogenic methane separation for both the Exxon Catalytic Coal Gasification and the Rockwell Hydrogasification processes currently undergoing development supported by DOE. This program is comprised of the following three tasks: screening, to define the most promising integration scheme for each gasification process; developing a process flowsheet, heat and material balance, P and ID, equipment specifications, utility summary, and plot plan for the selected scheme of each process; and preparing the detailed economics and issuing the final report. This interim report documents the results of the Task I study. The acid gas removal processes under study included Selexol, Rectisol, and Benfield HiPure for the Exxon CCG process; MEA, DEA, improved DGA, and Sulfinol for the Rockwell Hydrogasification process. The evaluations were performed using data from the prime coal gasification contractors and from the vendors of proprietary acid gas removal processes. This information, combined with Air Products' in-house capabilities in acid gas processes and cryogenic separation, allowed preparation of process designs and cost estimates for each of the integrated schemes. The gas treating cost was then determined for each combined system. The design criteria used in preparing the process designs are listed. The basis of economics for the capital cost and the gas treating cost estimate are also given.
