Distillation - Deprop
The interactive Distillation tutorial provides an overview, fundamental principles, process control principles and operating principles for a multi-component distillation column, using a depropanzier as an example and using voice, video, animation and graphics. The topics covered are:
The Distillation simulation is a rigorous and high-fidelity mathematical process model that provides a realistic dynamic response for a depropanzier distillation column.
A depropanizer unit separates a mixture, consisting primarily of C3 and C4 hydrocarbons, into two product streams. The lighter product, from the top of the unit, consists primarily of C3s; and the heavier product, from the bottom of the unit, consists of C4s and heavier hydrocarbons. The feed mixture to the unit is typically from either the deethanizer unit bottoms or the debutanizer unit overheads.
The depropanizer unit recovers the C3s from the feed mixture. The bottom product is further processed in the downstream units to recover other heavy hydrocarbons.
