Book Electrochemical Separation and Concentration of Hydrogen Sulfide from Gas Mixtures

Available in PDF, EPUB and Kindle. Book excerpt: A method of removing sulfur oxides of H.sub. 2 S from high temperature gas mixtures (150.degree.-1000.degree. C.) is the subject of the present invention. An electrochemical cell is employed. The cell is provided with inert electrodes and an electrolyte which will provide anions compatible with the sulfur containing anions formed at the anode. The electrolyte is also selected to provide inert stable cations at the temperatures encountered. The gas mixture is passed by the cathode where the sulfur gases are converted to SO.sub. 4 -- or, in the case of H.sub. 2 S, to S--. The anions migrate to the anode where they are converted to a stable gaseous form at much greater concentration levels (>10X). Current flow may be effected by utilizing an external source of electrical energy or by passing a reducing gas such as hydrogen past the anode.

Book High Temperature Electrochemical Polishing of H2S from Coal Gasification Process Stream Quarterly Progress Report January 1 1995 March 31 1995

Download or read book High Temperature Electrochemical Polishing of H2S from Coal Gasification Process Stream Quarterly Progress Report January 1 1995 March 31 1995 written by and published by . This book was released on 1995 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: An advanced process for the separation of hydrogen sulfide (H2S) 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 exiting syn-gas, and sulfur, which is condensed from an inert sweep gas stream. The process allows removal of H2S without cooling the gas stream and with negligible pressure loss through the separator. The process is made economically attractive by the lack of need for a Claus process for sulfur recovery. To this extent the project presents a novel concept for improving utilization of coal for more efficient power generation. Past experiments using this concept dealt with identifying removal of 1--2% H2S from gases containing only H2S in N2, simulated natural gas, and simulated coal gas. Data obtained from these experiments resulted in extended studies into electrode kinetics and electrode stability in molten melts. The most recent experiments evaluated the polishing application (removal Of H2S below 10 ppm) using the Electrochemical Membrane Separator (EMS). H2S removal efficiencies over 90% were achieved at these stringent conditions of low H2S concentrations proving the technologies polishing capabilities. Other goals include optimization of cell materials capable of improving cell performance. Once cell materials are defined, cell experiments determining maximum removal capabilities and current efficiencies will be conducted. Also, a model theoretically describing the preferred reduction of H2S, the transport of S2−, and the competing transport of CO2 will be investigated. The model should identify the maximum current efficiency for H2S removal, depending on variables such as flow rate, temperature, current application, and the total cell potential.
