SET FOR PURIFYING PETROLEUM FROM HYDROGEN SULPHIDE AND LOW MOLECULAR WEIGHT MERCAPTANS Russian patent published in 2022 - IPC C10G27/04 C10G27/06 

FIELD: petroleum industry.

SUBSTANCE: invention relates to sets for purifying petroleum from hydrogen sulphide and low molecular weight mercaptans, and can be used in the petroleum and gas production industry in the field petroleum processing. Invention relates to a set for purifying petroleum from hydrogen sulphide and low molecular weight mercaptans, including a high-sulphur petroleum supply pipeline, a buffer tank, a petroleum pump, a pressure petroleum pipeline with a mixing apparatus, connected in series, and a catalytic agent preparation and storage tank with a dosing pump. The set is additionally equipped with an oxygen reception or storage unit and an oxygen supply pipeline connected to the pressure petroleum pipeline via a supply assembly before the mixing apparatus; wherein the oxygen supply pipeline at the supply assembly is connected with the pressure petroleum pipeline at several equidistant oxygen intake sections, wherein the distance between the oxygen intake sections should prevent the formation of large volumes of gas phase in the pressure petroleum pipeline and the occurrence of explosion and fire hazard.

EFFECT: prevented formation of hard-to-remove deposits and separable cushion gases containing a high proportion of cushion nitrogen, simplified technology for purifying petroleum from hydrogen sulphide and low molecular weight mercaptans, reduced metal consumption due to the reduced list of equipment used, lower capital and operating costs, expanded scope of application of the set.
