FIELD: units for separation of hydrocarbon mixtures, for instance, gas condensate; may be used in production of gasoline and diesel fuels. SUBSTANCE: device has two partially accommodated in each other fractionating columns provided with inlet and outlets of product flows. A part of upper column is located with clearance in shell installed in middle part of lower column. In this case, lower column is separated from the upper column by partition made in the form of hydroseal connected with respect to fluid with pipe unions of spraying of upper column, and one of outlets of lower column is connected with middle part of upper column through heat exchanger.
