Styrene monomer, the full two-step chain

Benzene alkylated to ethylbenzene, purified, and dehydrogenated directly to styrene monomer — one connected flowsheet, not two standalone snippets.

The actual dark-mode canvas: benzene alkylated to ethylbenzene, purified, reheated, and dehydrogenated straight to styrene monomer — the same P&ID symbols you edit in the app.

One flowsheet, not two standalone snippets

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, stated rather than hidden (closing that loop needs a torn-recycle edge back into the alkylation column, which a real plant runs but this flowsheet doesn't).

Unit ops shipped for this vertical

Fixed-conversion reactor

A specified per-pass conversion on a key component — the shortcut counterpart to the equilibrium and kinetic reactors.

Run preset →
Heater / cooler

Duty- or outlet-condition-specified energy-balance stage.

Run preset →
Distillation column

Wang-Henke MESH column solver — the same rigorous solve at any scale.

Run preset →
Flash drum

Single-stage vapor-liquid equilibrium split at a fixed temperature/pressure.

Run preset →
Live plant integration

Stream alkylation/dehydrogenation conversion and both columns' reflux from your chain's OPC-UA server into this flowsheet's twin comparison — deviations from the solved conversion are flagged automatically.
