Malodorous gases control in a kraft pulp mill General Malodorous reduced sulphur compounds are produced in the kraft pulping process when cooking chemicals NaOH and Na2S reacted with lignin. These reactions formed malodorous gases as a form of total reduced sulphur (TRS), namely, methyl mercaptan (MM), dimethyl sulphide (DMS), dimethyl disulphide (DMDS), and hydrogen sulphide (H2S).
