Abstract:
A method of compressing a gaseous hydrocarbon-containing medium comprising:feeding a gaseous hydrocarbon-containing medium to a liquid-gas jet device; feeding a liquid hydrocarbon-containing medium by a pump under pressure to a nozzle of the liquid-gas jet device; forming a gas-liquid mixture in the liquid-gas jet device while mixing the gaseous hydrocarbon-containing medium and liquid hydrocarbon-containing medium, and absorbing a portion of the gaseous hydrocarbon-containing medium in the liquid hydrocarbon-containing medium, the gas-liquid mixture having a pressure exceeding the pressure of the gaseous hydrocarbon-containing medium; feeding the gas-liquid mixture from the liquid-gas jet device to a separator; separating the gas-liquid mixture into compressed gas and a liquid hydrocarbon-containing medium; removing the compressed gas and liquid hydrocarbon-containing medium from the separator; removing a portion of the liquid hydrocarbon-containing medium into a cracking and rectification unit in which the removed portion of the liquid hydrocarbon-containing medium is subjected to cracking with subsequent rectification in a rectifying column to provide a fresh liquid working medium; and combining the fresh liquid working medium with the liquid-hydrocarbon-containing medium removed from the separator.
