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).
The flowsheet
The solved topology — every unit op's real duty, conversion, or split, read straight off a genuine converged solve.
The stream table
Every stream's flow, temperature, pressure, and composition — real converged numbers, not placeholders.
