Advanced Process Modeling Topics Course Agenda

 Getting Started

• 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.

Advanced Columns

• 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.

Dynamic Depressurization

• 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.

Reactions

• 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.
