The overall goal of this program is to investigate the use of ion exchange membranes in the removal of acid gases during processing of natural gas or during production of H{sub 2} from synthesis gas. As part of this goal we are running a field test of candidate membranes on a natural gas stream to obtain extended performance data on acid gas transport. Additionally we are working on strategies for increasing the productivity and lifetime of these types of membranes. The specific objectives include: Evaluate candidate membranes, carriers, solvents, treatments and the effects of process conditions for separation of the acid gases CO{sub 2} and H{sub 2}S from H{sub 2}, CO and CH{sub 4}. Develop mathematical models to guide experimental work and for interpretation of results. Construct and operate an extended-use test facility to evaluate the long term stability and productivity of various membrane forms relative to acid gases. Develop thin film composite membranes as a possible route to higher productivity and lower cost membranes. Develop preliminary process design and economic analysis for the use of these membranes in gas cleanup.
