FIELD: petroleum chemistry. SUBSTANCE: mixture of light hydrocarbons is compressed using a liquid ejector where a stable hydrocarbon fraction is an active flow to yield a liquid phase containing 60% of components of C3+-raw, not less, and an active flow of ejector. Obtained liquid phase is compressed using a pump and subjected for rectification with isolation of an active flow of ejector and the special fractions. Method ensures to separate mixtures of light hydrocarbons of low pressure without the use of compressors. EFFECT: improved method of separation. 2 cl, 2 tbl, 1 dwg, 1 ex
