Amine Unit

Reducing sulfur emissions is a crucial goal for every refinery, driven by stringent environmental regulations and the need to minimize air pollution. Hydrogen sulfide (H₂S), a significant contributor to sulfur emissions, is generated during various refining processes, including hydroprocessing and cracking. The amine unit serves as the primary stage for removing H₂S, along with other sulfur-containing compounds such as carbonyl sulfide (COS) and carbon disulfide (CS₂). Key areas prone to corrosion include equipment such as amine absorbers, regenerator columns with reboilers, heat exchangers, and associated piping, where exposure to hot, rich, and lean amine streams can initiate damage mechanisms. Proper material selection, continuous process monitoring, and effective chemical control are essential to mitigate these risks and ensure reliable operations.
