High temperature membranes for H{sub 2}S and SO{sub 2} separations. Quarterly progress report, January 1, 1993--March 31, 1993

Description: High temperature membrane separation techniques have been applied to gas mixtures involved in coal utilization. For coal gasification, H{sub 2}S has been removed from the syn-gas stream, split into hydrogen which enriches the syn-gas, and sulfur which can be condensed from an inert gas sweep stream. For coal combustion, SO{sub 2} has been separated from the flue gas, with concentrated SO{sub 3} produced as a by-product. Both processes appear economically viable but each requires fundamental imp… more

High temperature membranes for H{sub 2}S and SO{sub 2} separations. Quarterly progress report, April 1, 1992--June 30, 1992

Description: Work has continued on application of this technology to polishing H{sub 2}S from simulated coal gasification process streams. Both stainless steel and MACOR housings were successfully used, with 98% (100 ppmv H{sub 2}S to 2 ppmv H{sub 2}S) removal observed at a flow rate of 230 cc/min and a process temperature of 700{degrees}C with stainless steel housings (Run 57) and greater than 80% (11 ppmv H{sub 2}S to less than 2 ppmv H{sub 2}S) at a flow rate of 100 cc/min and a temperature of 650{degree… more
