FIELD: rectifying plants for fractionating liquid hydrocarbons; oil and gas industries. SUBSTANCE: plant for rectifying C3-C6 hydrocarbons includes rectifying column whose inlet is connected with raw material supply line equipped with raw material reservoir and heat exchanger. Top of column is connected with propane-butane fraction discharge line and bottom is connected with pentane-hexane fraction discharge line which is connected to heat exchanger mounted before raw material reservoir. Plant is additionally provided with preheater mounted between raw material reservoir and heat exchanger; raw material reservoir is connected with propane-butane discharge line, thus making it possible to discharge separated light hydrocarbons from raw material reservoir past rectifying column. EFFECT: increased productivity of plant; reduced power requirements. 2 dwg
