METHOD AND UNIT FOR STABILISATION OF UNSTABLE GAS CONDENSATE MIXED WITH OIL Russian patent published in 2015 - IPC B01D3/14 C10G7/02 

FIELD: oil-and-gas industry.

SUBSTANCE: invention relates to the method of stabilisation of unstable gas condensate mixed with oil, which is implemented in two series operated strings fitted with contact and drain devices, from the top of the first column hydrogen sulphide, methylmercaptan and light hydrocarbons are separated, from the bottom deeply dimethyl- mercaptanised stabilite is separated which sent to the second rectifying column from which the hydrocarbonic fractions are separated which contain the mercaptans extracted later as odorants, nk-65°C, nk-75°C, or nk-130°C in which respectively ethyl mercaptan, isomerous and normal propyl mercaptan and isomeric and normal butyl mercaptan or mixes of the respective merkaptan are concentrated, and from the string bottom the heavy rest is taken away. The invention also relates to the unit for stabilisation of unstable gas condensate mixed with oil.

EFFECT: refining of oil and gas condensate from hydrogen sulphide and a methylmercaptan, production of the range of hydrocarbon fractions.
