- Summary
- An advanced process for the separation of hydrogen sulfide from coal gasification product streams through an electrochemical membrane is being developed. H₂S is 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. The process allows removal of H₂S without cooling the gas stream and with negligible pressure loss through the separator. The process is economically attractive by the lack of adsorbents and the lack of a Claus process for sulfur recovery. Research conducted during the present quarter is highlighted, with an emphasis on progress towards the goal of an economically viable H₂S removal technology for use in coal gasification facilities providing polished fuel for co-generation coal fired electrical power facilities and Molten Carbonate Fuel Cell electrical power facilities. Polishing application of this technology to coal gasification synthesis gas has been demonstrated with H₂S removals as high as 89.1% recorded. No successful runs with stainless steel housings have yet been achieved. However, since stoichiometric CO₂ removal with stainless steel housings has been achieved, H₂S removal is achievable.
