Amine Unit

Reducing sulfur emissions stands as a crucial goal for every refinery. Hydrogen sulfide, a prominent pollutant in major gas streams, is generated during various refining processes. The amine unit serves as the initial stage for removing H₂S along with other sulfur-containing compounds like COS or CS₂. Given its importance, amine treating requires thorough process management and corrosion control to ensure smooth and efficient operations. This chapter describes general process-related aspects of amine treating as well as major corrosion threats.
