HYDROCARBON GAS PROCESSING

摘要

A process and an apparatus are disclosed for the recovery of heavier hydrocarbon components from a hydrocarbon gas stream in a compact processing assembly. The gas stream is cooled, condensed and expanded to lower pressure and supplied as a feed to an absorbing means inside the processing assembly. A distillation liquid stream is collected from the absorbing means and directed into a heat and mass transfer means inside the processing assembly strip out its volatile components while cooling the gas stream. Distillation streams are collected from heat and mass transfer means and cooled sufficiently to at least partially condense it, forming a residual vapor stream and a condensed stream. The quantities and temperatures of the feeds are at a temperature whereby the major portions of the desired components are recovered in the stripped distillation liquid stream.
