A close-boiling isobutane/n-butane splitter as reported by Klemola and Ilme (Ind. Eng. Chem. Res. 1996, 35, 4579) — the relative volatility between the two isomers is small (~1.3), so the column needs many stages and a high reflux ratio for a sharp split, unlike the wider-boiling LPG splits elsewhere in this library.
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.
