Crude distillation (preset cuts)
An atmospheric crude column fractionating a petroleum feed (naphtha → kerosene → diesel → residue) into ordered side cuts — refinery support via pseudos.

A fuller atmospheric CDU: a crude/residue preheat exchanger, a desalter (wash water mixed in, then split off as brine), a fired heater, the multi-draw column, three steam side-strippers recovering kerosene / light gas oil / heavy gas oil, and an overhead condenser + three-phase reflux drum (fuel gas / naphtha / sour water). A pumparound heat-integration loop (drawing liquid off an interior stage, cooling it externally against crude, and returning it colder to preheat the column's own upper trays) was attempted -- both a 2-loop and a 1-loop version -- but proved too numerically expensive to converge in reasonable time and was dropped rather than shipped half-tuned; everything else in the reference PFD is real. From the ChemSep casebook (crude distillation).
