Open this exact flowsheet in the workspace, already solved — tweak a spec and re-run.
An atmospheric crude column fractionating a petroleum feed (naphtha → kerosene → diesel → residue) into ordered side cuts — refinery support via pseudos.
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.
