Abstract

Processes and equipment for compact processing components used to recover propane, propylene and heavier hydrocarbon components from hydrocarbon gas streams were obtained. Disclosure With the gas stream being cooled Is expanded to a lower pressure And was fed to Adsorption device The liquid stream of the first distillation from the absorption device and fed to the mass transfer device. The first distillation vapor stream from the mass transfer device is cooled to condense. Some of these vapor flows to create residual and condensed vapor flows. Condensed current They are supplied as a top feed to the adsorption device. The vapor stream of the second stream distillation from The adsorption device is heated by cooling the first distillation vapor stream. Combined with residual vapor current and heated by gas cooling The liquid stream of distillation, the second stream from The mass transfer equipment is heated in the heat and mass transfer device to chase the components that Evaporate

Claims (1)

1. A process for separating gas streams containing methane, C2, C3 and heavier hydrocarbon components into gaseous parts. The volatile residues and volatile components are somewhat smaller than those containing the main C3 component and the heavier hydrocarbon component, where (1) the aforementioned gas stream was cooled in the first heat exchanger (2). The aforementioned cooled gas stream was expanded.
