Research output: Patent


A gaseous mixture, comprising CO.sub.2, H.sub.2, H.sub.2S and optionally CO, is separated into an H.sub.2 or H.sub.2 and CO product stream (H.sub.2/CO product stream), and a CO.sub.2 enriched stream containing at least one combustible component selected from H.sub.2S, H.sub.2, CO and any additional combustible components present in the gaseous mixture. A support fuel stream, comprising one or more combustible components, is combusted to form a stable flame, and the CO.sub.2 enriched stream and flame are contacted in the presence of sufficient O.sub.2 to combust all or substantially all of the combustible component(s) present in said CO.sub.2 enriched stream. A CO.sub.2 product stream is formed from said combustion effluent. The support fuel stream may be generated from the process of generating or separating the gaseous mixture or from the H.sub.2/CO product stream. Where the CO.sub.2 enriched stream contains H.sub.2S, the support fuel stream may also be a stream obtained off-site that comprises H.sub.2S.
