Question 1: Please briefly describe the SCOT process in sulfur recovery. Answer: The SCOT process was developed in the early 1970s by the British and Dutch company Shell International. It involves adding an exhaust gas treatment unit to a Claus plant; the exhaust gases from the Claus plant, along with reducing gases, are heated and fed into the SCOT reactor. There, under the action of cobalt/molybdenum catalysts, sulfur and SO2 are reduced to H2S. This hydrogen sulfide is then condensed and dehydrated before being absorbed in an amine absorber, thereby purifying the exhaust gases. As a result, the plant achieves a sulfur recovery rate of over 99.5%.

The SCOT process is an exhaust gas treatment process developed by Shell. It is currently one of the most widely used sulfur recovery processes in the world, with rapid development; it effectively combines scale and environmental benefits with favorable investment returns, thanks to its ability to remove H2S from exhaust gases

The SCOT process was developed in the early 1970s by the British and Dutch multinational Shell Group. It builds upon the Claus unit by adding an exhaust gas treatment system; the exhaust gases from the Claus unit together with the reducing gas are heated and fed into the SCOT reactor, where CO and MoS as well as SO2 are reduced to H2S. This hydrogen sulfide is then condensed and dehydrated before being sent to an amine absorption tower, allowing for the recovery of over 99.5% of the sulfur contained in it.
