The invention concerns gas and petroleum industry and can be used at development of gas-condensate fields, in particular at preparation for transport and use of hydrocarbon raw material. A method of preparation of the hydrocarbon production of gas-condensate field for transport includes supply of crude gas for separation, isolation of stratum water, condensate and gas, cooling gas, low-temperature absorption of the fraction of propane-butane and of heavier hydrocarbons by degreased absorbent, regeneration of absorbent with steaming of absorbed hydrocarbons. Into the flow of gas, between cooling device and absorber, the absorbent is additionally introduced by portions through special devices, which are located at specific distances along the flow of gas, and their number is not less than two. Steam-stripped methane and ethane, which are dissolved in the absorbent, return to the gas flow at inlet of compressor units. The invention provides increase of removal of propane, butane and heavier hydrocarbons at smaller quantity of circulation of absorbent. |
