METHOD OF PREPARATION OF SULPHURETTED OIL AND ASSOCIATED GAS Russian patent published in 2016 - IPC F17D1/65 

FIELD: oil and gas industry.

SUBSTANCE: invention can be used in the oil and gas industry in the preparation of oils with a high content of hydrogen sulphide. A method of preparing sulphuretted oil and associated gas comprising separation sulphuretted oil in the first and second stages of separation after heating sulphuretted oil installing heating oil, stripping the hydrocarbon gas not containing hydrogen sulfide, in the desorption column, separation of the oil in the low pressure separator is introduced and reagent mixing hydrogen sulfide catalyst, compression at the compressor station of associated gas from the second stage separation of oil, low pressure separator and stripper. After compressing the associated gas is supplied to the oil supply of the first stage of separation or division of flow of the first stage in the supply pipelines of appropriate separators, skipping at least 20% in the coming training sulphuretted crude oil.

EFFECT: increase in the yield of marketable oil, increase the efficiency of stripping the hydrogen sulfide from oil refining.
