Aspen HYSYS Lecture 12 Separation Columns Demathanizer modelled as reboiled absorber column

Recovery of natural-gas liquids (NGL) from natural gas is quite common in natural gas processing. Recovery is usually done to:
1. Produce transportable gas.
2. Meet a sales gas specification.
3. Maximize liquid recovery.
HYSYS can model a wide range of different column configurations. In this simulation, that will span for two lectures, an NGL Plant will be constructed, consisting of three columns:
De-Methanizer (operated and modelled as a Reboiled Absorber Column).
De-Ethanizer (Distillation Column).
De-Pronanizer (Distillation Column).
Only the De-Methanizer is modelled in this Lecture.
