HYSYS flash calculation

To demonstrate the earlier procedure, the problem of flash distillation is considered. Flash calculations are very common, perhaps one of the most common chemical engineering calculations. They are a key component of simulation packages like Hysys and Aspen. 

In our work, Henry s coefficient for HjS was calculated with HYSYS flash module without interaction parameters. 

The HYSYS simulation package is used for general flash calculation and to estimate the physical properties. 

The flash calculation is performed using the HYSYS simulation package and the Peng-Robinson equation of state. The condition corresponds to type 1. 

Aspen HYSYS used the concept of the fluid package to contain all necessary information for performing flash and physical property calculations. This approach allows you to define all information (property package, components, hypothetical components, interaction parameters, reactions, tabular data, etc.) inside a single entity.
