Aspen RefSYS

We start by opening Aspen HYSYS. The typical path to Aspen HYSYS is to enter the Start > Programs > AspenTech > Aspen Engineering Suite > Aspen HYSYS. Early versions may include a menu entry titled Aspen RefSYS. We dismiss the Tip dialog and select File > New > Case. We wish to include fractionation, so we do not choose FCC alone.

Step 9 Input catalyst information provided by vendor. After completing this step, Aspen RefSYS will solve the model automatically. 

One of HCR model s applications is used to investigate different oprerating scenarios and help answering what-if question by running simulation experiments. This workshop demonstrates how to use developed Aspen RefSYS HCR model to investigate the effect of WART of HCR reactor and feed flow rate on product distribution. In real operation, the only way to tune WART is to change inlet temperature of reaction bed. In this workshop, we will change inlet temperatures of the three HCR beds at the same time to perform case study.
