HYDROGEN SULPHIDE AND MERCAPTAN NEUTRALISER AND METHOD OF USING SAID NEUTRALISER Russian patent published in 2011 - IPC C10G29/20 

FIELD: chemistry.

SUBSTANCE: described is a hydrogen sulphide and/or light mercaptan neutraliser, containing urotropin and formalin, which additionally contains carbamide-formaldehyde concentrate (CFC) - a product of condensation of carbamide with gaseous formaldehyde in molar ratio 1: (4-6) and a bactericidal preparation with the following ratio of components in wt %: urotropin 10-27; carbamide-formaldehyde concentrate 5-40; bactericide 3-20; formalin - the rest. Described is another version of the neutraliser, which additionally contains sodium or potassium hydroxide in amount of 0.1-1%. The invention also describes a method of cleaning oil, water-oil emulsions, oil products and hydrocarbon gases from hydrogen sulphide and/or light mercaptans via treatment with a chemical reagent in form of the neutraliser described above.

EFFECT: efficient neutraliser, having high processability and reaction capacity, and providing high degree of purification of oil, water-oil emulsions, oil products and hydrocarbon gases from hydrogen sulphide and light mercaptans at low specific consumption.
