Abstract
The invention provides a liquids recovery process useful for the separation and recovery of C.sub.3.sup.+ liquid hydrocarbons from gas mixtures containing high concentrations of lighter components such as are produced by the dehydrogenation of liquefied petroleum gases or by the catalytic cracking of heavy oils. The recovery process employs an absorption refrigeration cycle to supply high level refrigeration to the process; the absorption cycle utilizes low pressure steam or a heated fluid derived from secondary heat recovery of a process flue gas to effect heating in the absorption refrigeration cycle.
