Improved acetylene recovery process and apparatus.

摘要

Improved process and apparatus is disclosed for the recovery of acetylene from gas containing acetylene and ethylene comprising: contacting said gas (11) with acetylene solvent to form a loaded solvent solution (13); heating said loaded solvent solution by passing through a first stream conduit (A) of a heat exchange zone having a plurality of non-interconnecting stream conduits in heat exchange thermal contact; separating the resulting liquid/vapor (14) into liquid (16) and vapor (15) phases; passing said liquid phase to a second stream conduit (13) of said heat exchange zone passage to a downstream further acetylene separation purification step (17), and cooling warm denuded acetylene solvent by passage through a third stream conduit (C) of said heat exchange zone and then further cooling (22,23,24,18) before passageto said acetylene solvent contacting zone.
