Web14 feb. 1995 · Thermal recovery processes are well established enhanced oil recovery techniques and are widely applied for recovering heavy oil, heavy oil sands, and shale oil. During thermal recovery the formation of hydrogen sulfide, H2S, including the H2S induced reduction of sulfate to H2S, has to be taken into account in the reservoirs. WebVarious processes generate hydrogen-rich offgases, among them ethane steam cracking, propane and butane dehydrogenation, chlor-alkali processing, and catalytic reforming. This article examines different techniques that are available for recovering and purifying hydrogen from these streams and reviews the economic drivers behind these techniques.
