Abstract
The olefin-hydrogen effluent vapor stream from a dehydrogenation process is separated by a cryogenic separation method utilizing a cryogenic separation system. The method does not require external refrigeration and reheats and portions an expander feed stream to extract energy and controls the warm end and cold end temperature differences in the primary heat exchanger to provide energy savings and economical operation and material use.
