Styrene monomer via ethylbenzene dehydrogenation
Ethylbenzene dehydrogenates over an equilibrium/conversion reactor to styrene monomer plus hydrogen — the endothermic reaction that supplies the world's polystyrene/SBR-rubber feedstock. A downstream column recovers unreacted ethylbenzene overhead for recycle while polymer-grade styrene leaves the bottoms. Vasudevan design, Ind. Eng. Chem. Res. 2009, 48, 10941 (Figure 15.1).

View & openIntegrated styrene chain: benzene to styrene monomer
The full two-step styrene chain connected as one flowsheet rather than two standalone process snippets: benzene alkylated with ethylene to ethylbenzene, purified in a recovery column, then fed directly to the dehydrogenation reactor that makes styrene monomer. The unreacted ethylbenzene the dehydrogenation column recovers is reported as its own product stream rather than recycled back onto the alkylation feed (an honest simplification — closing that loop needs a torn-recycle edge back into ALKCOL, which the plant does but this flowsheet does not).
