CONVERTER OF SULFUR COMPOUNDS AND WAYS OF ITS USE Russian patent published in 2017 - IPC B01D53/52 C10G29/20 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to a process of neutralization of hydrogen sulphide and low molecular weight mercaptans in crude and prepared oil, gas condensate, hydrocarbon gases, oil products, heavy oil residues and can be used in oil and gas exploration and oil and gas industries. Neutralizer hydrogen sulfide and mercaptans is a water-based composition comprising ethanedial (Glyoxal), glycols or mixtures of glycols, derivatives of amines (aliphatic, alicyclic, aromatic, fatty-aromatic, heterocyclic and polycyclic amines, acyclic, cyclic di- and polyamines) with the amount of nitrogen atoms per molecule from 1 to 8, the following composition (wt %): ethanedial (glyoxal) - 10-40, glycol or mixture of glycols - 0.1-30, amine derivatives - 0.001-10, water - the rest.

EFFECT: invention neutralize low molecular weight mercaptans and hydrogen sulfide, providing deep cleansing of hydrocarbon oil and hydrogen sulfide and mercaptans to form a chemically and thermally stable products neutralize a wide temperature range, and the possibility of storage and use at a low temperature catalyst.
