An advanced process for the separation of hydrogen sulfide from coal gasification product streams through electrochemical membrane is being developed. H2S is removed from the syngas stream, split into hydrogen, with the existing syngas, and sulfur. Past experiments dealt with removal of 1-2% H2S from gases containing only H2S, nitrogen, and simulated coal gas. The most recent experiments evaluated the polishing application using Electrochemical Membrane Separator. Removal efficiencies of over 90% were achieved
