FIELD: oil and gas industry.
SUBSTANCE: invention refers to oil treatment methods, and namely to stabilisation and refining methods of oil from hydrogen sulphide and light mercaptans. The invention refers to stabilisation and refining methods of oil from hydrogen sulphide and light mercaptans and consists in oil heating with further blowing-off with light hydrocarbon gas in the column with a ABP head piece, in which oil is separated into two flows; one flow comprising 70 to 90 vol.% is heated up to 110-180°C and supplied to the middle part of the column; the second non-heated flow with temperature of 40-60°C and comprising 10 to 30 vol.% is supplied to upper part of the column; low-sulphurous light hydrocarbon gas of the first separation stage is supplied to the column bottom.
EFFECT: refining from hydrogen sulphide and mercaptance; reduction of costs; absence of formation of secondary hydrogen sulphide.
