Oxidation of mercaptans (Merox)

Mercaptans are undesirable components in finished petroleum products as they adversely affect their quality. These sulfur compounds are removed by the Merox process which consists in the oxidation of mercaptans. For that purpose, the mercaptans are extracted and then oxidized by excess air to form alkyl disulfides. Typically, process gas analyzers monitor the oxidation process by measuring the oxygen level in the excess air vent downstream of the disulfide separator.
