Biodiesel methyl esters (C16 / C18) split at 0.05 bar — vacuum keeps the bottoms under 515 K; near-total C16 recovery overhead and ~98% C18 in the bottoms (the two components' relative volatility caps bottoms purity there — more stages/reflux do not push it further). From the ChemSep casebook (Fatty_Acids, as methyl esters).
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.
