ABSTRACT:
Alkylaromatic hydrocarbons are dehydrogenated in admixture with steam, with the dehydrogenation zone effluent being condensed to form a water stream which is purified in a stripping column. The stripping column is reboiled by indirect heat exchange against the effluent of the dehydrogenation zone. The steam-rich overhead vapor stream of the stripping column is mixed directly into the dehydrogenation zone feed stream without intermediate condensation or pressurization.
