TH124886B - Hydrocarbon gas processing - Google Patents

Abstract

Processes and equipment for compact processing components used in component recovery. C2 (or C3 component) and heavier hydrocarbon components from the hydrocarbon gas stream were disclosed, with the gas stream being cooled and divided into the first, second, with the first being cooled to condense that first. The whole is actually expanded to the lower pressure and supplied as an upper shield to the adsorption device, and the second current is amplified to the lower pressure and supplied to the bottom of the suction device. As mentioned above, the vapor stream of the distillation from the adsorption device is heated by cooling the gas stream and the first stream.The liquid stream of the distillation from the adsorption device is fed to the heat and mass transfer device for the flow. The liquid heats and expels the volatile components of the fluid stream while cooling the gas stream. Adsorption devices and heat and mass transfer devices are in the processing assembly.

Claims (1)

1. a process for separating gas streams containing methane. C2, C3 component and heavier hydrocarbon constituents form volatile residual gases and relatively less volatile components that contain the main component C2, C3 component and heavier hydrocarbon component, or C3 component and hydrocarbon component that Heavier than the foregoing, where (1) the aforementioned gas stream is divided into the first and the second (2) the first part is cooled (3) the second part is cooled (4). The first part that was chilled at the farm.
