FIELD: petrochemistry. SUBSTANCE: essence on invention consists in that fresh liquid working medium of jet pump plant is used in form of distillate of additional rectification column 4. Liquid hydrocarbon-containing medium is withdrawn from its circulating circuit formed by jet device 1, separator 2 and pump 3, to cracking and rectification plant 5 where liquid medium is subjected to cracking in cracking unit 6 with subsequent rectification in rectification column 7. The other version of the method embodiment is distinguished by the fact that fresh liquid working medium is used in form of distillate of rectification column 7 and liquid hydrocarbon-containing medium is withdrawn from circuit of its circulation in said rectification column. As a result, method provides for its higher economic efficiency of compression and supply under pressure of gaseous hydrocarbon- containing gases with their simultaneous drying of compressed gas from heavier hydrocarbons with practically full exclusion of unproductive losses of hydrocarbon-containing products that leads to higher ecological safety of production process. EFFECT: higher efficiency of method. 4 cl, 1 dwg
