FIELD: gas and oil industry.
SUBSTANCE: invention relates to production of propane by separating unstable hydrocarbon condensate obtained at reprocessing of hydrocarbon gases with wide fraction of light hydrocarbons and propane fraction as final products. Proposed plant has column-de-ethanizer with bottom heater and top sprayer unit and outlet of de-ethanization gas in upper part and stabilized condensate in lower part. Middle part of strengthening section of column-de-ethanizer is provided with outlet of liquid from plate, corresponding to required concentration of propane fraction, which is connected with upper part of propane production column. Said column is essentially stripper with bottom heater, propane outlet ion lower part and hydrocarbon vapors outlet in top part which is connected with upper part of column de-ethanizer.
EFFECT: reduced capital outlays by decreasing number and size of used equipment, reduced energy consumption.
