FIELD: technological processes.

SUBSTANCE: invention relates to methods for treatment of hydrocarbons, hydrocarbon-containing geological materials. Method of processing hydrocarbons obtained from hydrocarbon deposit includes: (a) preparing a mixture of liquid hydrocarbons and gaseous components obtained from hydrocarbon deposit, in which gaseous components contain hydrogen sulphide and mercaptans; (b) separation of liquid hydrocarbons from gaseous components; (c) contacting gaseous components with stripped absorption oil, as a result of which mercaptans are absorbed by stripped absorption oil and saturated absorption oil is formed; (d) separating gaseous product containing hydrogen sulphide from saturated absorption oil; (e) treatment of gaseous product for removal of hydrogen sulphide to obtain depleted fuel gas and (f) treatment of liquid hydrocarbons obtained at step (b), by mixing with stripped absorption oil, saturated absorption oil, mixture of saturated and lean absorption oil, equivalent hydrocarbon or with equivalent hydrocarbon capable of dissolving liquid hydrocarbons, and saturated absorption oil obtained at step (d), to reduce viscosity before transportation to oil refinery for processing. Disclosed is a version of method.

EFFECT: removal of sulphur-containing compounds, particularly mercaptans from hydrocarbon streams.
