Propane / isobutane / n-butane separated in one thermally-coupled dividing-wall column (shortcut splits): three on-spec products from a single shell. From the ChemSep casebook (LPG_DWC, Gas Processing Dec 2018).
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.
