The other sulfides: Organic sulfur species in amine solvents

This article examines the behavior of carbonyl sulfide (COS), C1–C5 mercaptans (R1SH–R5SH), methyl ethyl sulfide (MES), dimethyl sulfide (DMS) and dimethyl disulfide (DMDS) in amine solvent systems. The objective here is to explore the current state of open industry knowledge in this area and compare it to gathered field test data. This article will highlight what is and what is not known and is a good starting point for future study on this topic, as not much field data has been previously published. The article contains: A review of the chemistry of organic sulfur species in amine systems Trending and analysis of key operating parameters for data from 50 industrial amine solvent ab
