Adiabatic ethylene oxide hydrolysis to ethylene glycol in a CSTR — the classic reactor-safety teaching case (Fogler). Solves to a safe steady conversion at the design feed temperature; switch to the Dynamic solve mode and step the feed temperature up a few degrees to watch the exotherm and the Arrhenius rate feed back on each other (thermal runaway), self-limited as the reactant depletes.

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.
