Advanced Process Modeling Topics Course Agenda
Use core flowsheeting functionality to build a Turbo Expander plant flowsheet with a multi-pass exchanger and other key unit operations (heater, separator, column, set).
Workshop: Use the Aspen HYSYS LNG Exchanger to simulate multi-pass exchangers. Add Columns using the Input Expert. Customize the Workbook and PFD. Use stream property correlations.
Extending HYSYS Functionality
Demonstrate how automation can be used to increase the capabilities of Aspen HYSYS.
Workshop: Create a User Variable to report user defined quantities. Use Aspen Simulation Workbook to create a custom interface.
Simulate columns that do not adhere to the usual configurations.
Workshop: Customize a column with a sizable heat exchanger. Perform tray sizing and Rating calculations using the Tray Sizing utility.
Spreadsheets and Case Studies
Use a spreadsheet to calculate a simplified profit for the Turbo Expander plant.
Workshop: Import and export variables to and from the Spreadsheet; add complex formulas. Use the Case Study to evaluate flowsheet scenarios.Optimization
Use the optimization feature in Aspen HYSYS to identify optimal operating conditions.
Workshop: Use the available optimization methods to maximize profit in a Turbo Expander plant flowsheet.
Modeling Real Separators
Model liquid/vapor carryover so that your model matches your process mass balance or separator design specification.
Workshop: Estimate carryover based on vessel geometry and inlet conditions. Model an exit device to reduce liquid carryover.
Size and rate pressure safety valves to safely meet plant conditions using the Dynamic Depressuring utility.
Workshop: Use the Dynamic Depressuring utility to size a blowdown valve for a vessel and size a PSV for a fire case.
Specify equilibrium and conversion reactors using reaction sets defined in the simulation basis.
Workshop: Model a simplified synthesis gas flowsheet using a variety of reactor types.
Heat Exchanger Rating
Convert an existing heat exchanger from a simple design model to a rigorous rating model.
Workshop: Use Aspen Shell and Tube Exchanger as the rating engine for a heat exchanger inside Aspen HYSYS.
