Open this exact flowsheet in the workspace, already solved — tweak a spec and re-run.
Benzene/toluene/ethylbenzene split into three purified products by a single rigorous dividing-wall column (prefractionator + two coupled main columns) instead of two ordinary columns in series — the thermally-coupled route real DWC retrofits use.
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.
