FIELD: chemical industry.
SUBSTANCE: present invention relates to a method of oxidising one or more thiol compounds from an alkali stream and a device for carrying out said process. Method includes the following steps: A) passing a mixed stream containing an alkali stream into an oxidation tank containing a housing and a neck, where the housing comprises one or more packing elements, and the neck comprising a nozzle, a distributor and a mesh, and B) passing the stream of oxidised alkali into the separation vessel, comprising a first chamber and a second chamber, wherein the first chamber comprises a mesh coated with a coating.
EFFECT: disclosed invention reduces amount of mercaptans in spent alkali.
