FIELD: vacuum engineering. SUBSTANCE: invention is designed for industrial fields where evacuation must not be accompanied with water and air pollution with hazardous substances. Method includes condensation of gas-vapor mixture with simultaneous suction of gases and vapors directly from apparatus in condensation ejecting upright. As working condensing and ejecting substance, liquid is used with low vapor pressure and which is of the same physical nature as substances to be condensed. The liquid, which is given rotational movement, is fed in several points at angle 0-14 deg. to upright axis. EFFECT: enhanced efficiency, reliability, and safety of process and reduced power consumption. 11 cl, 9 dwg
