ABOUT THE COURSE

The Aspen Basic Process Modeling Course will show you how to model and simulate Processes, analysis of unit operation will help you in order to optimise the Chemical Plant. This is helpful for students, teachers, engineers and researchers in the area of R&D and Plant Design/Operation.

Course Outline

DAY I: Propane Refrigeration Loop and Refrigerated Gas Plant::

• Add and connect operations to construct a simple flowsheet.

• Use the graphic interface to manipulate flowsheet objects and provide a clearer representation of the process.

• Understand how to process information has propagated both forwards and backward.

• Convert simulation cases to templates.

• Workshop: Build and analyze a propane refrigeration loop simulation.

• Install and converge heat exchangers.

• Use logical operations: Adjust and Balance.

• Workshop: Model a simplified version of a refrigerated gas plant.

DAY II: NGL Fractionation Train Oil Characterization and HP Separation

• Model distillation columns with the assistance of the Column Input Expert.

• Manipulate column specifications to better represent process constraints.

• Evaluate utility requirements using the Process Utility Manager.

• Workshop: Model a two-column natural gas liquid (NGL) recovery plant.

• Introduce Oil Characterization in Aspen HYSYS.

• Use the Aspen HYSYS Spreadsheet and Case Study functionality.

• Workshop: Use the Oil Environment to characterize a crude assay and then employ the Case Study and Spreadsheet operation to determine how the Gas Oil Ratio (GOR) varies with pressure.

DAY III: Gas Gathering System and Two-Stage Compression

• Simulate a gas gathering system located on varied terrain using the steady-state capabilities of Aspen HYSYS.

• Workshop: Use the pipe segment and the Hydraulics subflowsheet to model a piping network in Aspen HYSYS.
