    Show how to convert a steady-state simulation to a dynamic simulation.

    Dynamic simulation allows users to investigate how fluctuations influence the performance of the overall process—crucial to process control. Included in this module are steps to convert a steady-state simulation to a dynamic simulation, how to create parameter fluctuations and observe the dynamic effects. Teach your students controller tuning, pressure relief, and tank filling and draining.

    Demo the essentials of process design.

    Process design simulation allows the engineer to explore and evaluate different alternatives that best meet process requirements. Included in this module are a set of iterations to produce a basic process design.



    Access the largest physical property database.

    The accuracy of physical property data is a pre-requisite for process design, simulation, troubleshooting and optimization. Included in this module are step by-step-examples on how to access the vast amount of physical data in Aspen Plus, how to create new molecules and estimate their properties, and how to use physical properties for process design.



    Teach how to model reactors.

    Modeling reactors provides the basis for how chemical reaction and kinetics affect the process. Included in this module are examples on how to use simulation for plug flow reactors, continuously stirred tank reactors (CSTR), and batch reactors.



    Teach how to model shortcut and rigorous distillation columns.

    Process simulation allows users to test the feasibility of different separations and compare and optimize designs. Included in this module are instructions on how to simulate distillation columns using shortcut design calculations (DSTWU model) and a more rigorous multistage distillation model (RadFrac).



    Teach material and energy balances across a process flowsheet.

    Heat and material balances can help solve for stream compositions and state variables (T, P, etc.). Process simulation can be utilized to solve for complex problems, such as a process flowsheet. This module includes instructions on how to use Aspen Plus® to simulate a simplified chemical process.



    Show thermodynamics and flash modeling.

    Physical properties and thermodynamics are essential to chemical engineering simulation. Included in this module are step-by-step examples on how to use simulation for steam table, equation of state, and flash calculations.
