Abstract
A process and an apparatus are disclosed for a compact processing assembly to recover C2 components (or C3 components) and heavier hydrocarbon components from a hydrocarbon gas stream. The gas stream is cooled and divided into first and second streams. The first stream is further cooled to condense substantially all of it, expanded to lower pressure, and supplied as top feed to an absorbing means. The second stream is also expanded to lower pressure and fed to the bottom of the absorbing means. A distillation vapor stream from the absorbing means is heated by cooling the gas stream and the first stream. A distillation liquid stream from the absorbing means is fed to a heat and mass transfer means to heat it and strip out its volatile components while cooling the gas stream. The absorbing means and the heat and mass transfer means are housed in the processing assembly.
