petroleum processing. SUBSTANCE: mixture of gas extractant with steam originated from asphalt and deasphaltizate stripping columns is fed into liquid-gas jet apparatus, which simultaneously receives pressurized water, which, flowing out of nozzle, compresses and condenses water steam and extractant. Mixture of water with liquid extractant from liquid-gas jet apparatus is fed into separator, wherein liquid extractant is separated from water, after which liquid extractant is directed into special container and water is pumped to nozzle of liquid-gas jet apparatus. As steam condensate accumulates in separator, extra water is withdrawn. Installation is provided with liquid-gas jet apparatus, pump, and separator. Pump outlet is connected to liquid inlet of liquid-gas jet apparatus, whose gas inlet communicates with outlet for mixture of gas extractant with steam coming out of asphalt and deasphaltizate stripping columns. Liquid-gas jet apparatus outlet is connected to separator, whose water outlet is connected to pump inlet and liquid extractant outlet to liquid extractant container. EFFECT: intensified extractant condensationprocess and improved reliability and quality of operation of deasphalting installation, whose structure is simplified. 11 cl, 1 dwg
