Abstract

Processes and equipment for compact processing components used in component recovery. C2 (or C3) and heavier hydrocarbon components from the ide carbon stream were exposed, with the gas stream being cooled and divided into the first and second, with the first being cooled, being expanded. The second flow is expanded to the lower pressure and is supplied as a bottom feed to the lower adsorption device. The distillation fluid stream from the bottom of the lower adsorption device is heated in the heat and mass transfer device to expel the volatile components of the liquid stream. The heat and mass transfer device is cooled by a vapor stream of the distillation from the top of the upper sorbent to create a condensed current that is supplied as the top feed to the upper sorbent as follows. say

Claims (1)

1. A process for separating gas streams containing the C2 component, the C3 component, and the heavier hydrocarbon component into a volatile residual gas fraction and a relatively less volatile fraction with the main component. C2, C3 component and heavier hydrocarbon component, or C3 component and heavier hydrocarbon component, where (1) the aforementioned gas flow is divided into the first part and the second (2) part. Cured (3) The second part of the above was cooled (4) The first chilled part said
