Workshop 6.3 - Model Applications to Process Optimization

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. 

Step 1 Hold the model to avoid automatic calculation while defining variables for simulation experiment

Step 2 We need to add a spreadsheet in Aspen HYSYS to make tuning three inlet temperatures possible. Click flowsheet — add operation or click FI2 .
