Distillation column

Tray numbering

Tray numbers increase from top to bottom. Tray 1 is the top tray, and the highest tray number is at the bottom.

Inputs

  • Number of Trays: Total number of trays in the column.
  • Inlet Tray Number: Tray index for the feed stream (top → bottom numbering).

Outputs

  • Overhead vapor product (top outlet).
  • Bottoms liquid product (bottom outlet).

Three-phase separator

Split an inlet into vapour, light liquid, and heavy liquid outlets.

Absorber

Equilibrium-tray absorber.
