Abstract:
A process for the production of styrene monomer from ethylbenzene comprising the steps of:a. catalytically dehydrogenating said ethylbenzene in the presence of steam thereby catalytically producing a dehydrogenation effluent gas containing unreacted ethylbenzene and lighter components and styrene monomer and heavier components; b. scrubbing said effluent gas with reflux to remove at least a portion of said styrene monomer and heavier components from said effluent gas; c. condensing a portion of said scrubbed effluent gas thereby producing a liquid organic dehydrogenation mixture; and d. using a portion of said liquid organic dehydrogenation mixture as said reflux for said step of scrubbing.
