What’s New in V10: Troubleshoot complex processes using advanced EO in Aspen HYSYS

Course Id:  EHY301   |   Duration:  0.50 day(s)   |   CEUs Awarded:  0.4   |   Level:  Advanced

Course Objective

In this hands-on workshop, you will use Equation Oriented (EO) Capabilities in Aspen HYSYS to simulate a fully integrated Crude Distillation Unit preheat train. All the pump around and products from the column are integrated with the heat exchangers in the preheat train using recycle operations. In the conventional mode such a complex simulation is difficult to converge and takes long time. You will convert this case into Equation Oriented mode, add EO specifications to represent actual plant operation and perform sensitivity studies for better understanding of operational synergies.
