Abstract
A cryogenic process for the separation of one light gas component from a heavier gas component in a gas feed stream, by injecting a liquid hydrocarbon additive stream into the top or upper portion of a dephlegmator-heat exchanger, to increase the rectification temperature, or to maintain the temperature and reduce the additive flow rate relative to the respective values required with a conventional, single stage condenser.
