Middle Scale Hydrogen Sulphide Conversion and Valorisation Technologies: A Review

Abstract The growing energy demand, together with the depletion of sweet gas reservoirs, impose monetization ultra‐sour natural fields a high H 2 S content. To date, in large scale facilities, is removed from through amine washing and it converted to sulphur Claus process. process leading conversion technology for applications. Regarding small plants, scavengers are most efficient widely spread choice. On other hand, present middle options show quite operating costs. Therefore, research efforts devoted developing new intermediate alternatives lower costs easier operability. When process, study state‐of‐the‐art first essential step. No systematic review valorisation technologies available literature. fill this gap, aim work summarize processes considering both commercial novel tendencies conversion. For each technology, details about conditions discussed typical application provided, when possible, corresponding pros cons.
