Aspen Custom Modeler Overview

Aspen Custom Modeler is specifically designed for development and use of custom process models

With Aspen Custom Modeler you can:

– Quickly and easily develop custom unit operation models, including your specific expertise or proprietary know-how

– Store these models in libraries for others to use

– Build these models into complete simulation flowsheets

– Run in 4 different modes:

Steady state

Dynamic

Parameter estimation

Optimization (steady-state or dynamic)

– Package and deploy completed simulations for use across your enterprise


6

Uses Aspen Properties

Aspen Properties is integrated into ACM, maintaining the rigorous property calculations in Aspen Plus

You can access Aspen Polymers to use in custom modeling


7

Easy to Learn

Started here less than a year ago and developed the rate-based flash model

Easy to learn language

Simple troubleshooting using informational messages

Variety of examples available

Challenge Solution Result Challenge

Modeling and Optimization of an Ethylene Oxide Reactor using Aspen Custom Modeler Reliance Industries Ltd.

Model and optimize an Ethylene Oxide Reactor

Needed a custom model to:

Obtain maximum throughput within established constraints

Predict effect of process conditions on catalyst

Understand and prevent side reactions

Perform what-if studies and sensitivity analysis

Optimize process control and operating conditions

Ref: Vasudha Mallikondla, Reliance Industries Limited

AspenTech OPTIMIZE, Boston, MA, May 2013


15

Solution Result

Developed custom simulation with Aspen Custom Modeler

Estimated kinetic parameters and deactivation parameters for the EO reactor

Performed model validation and performance prediction

Used ACM model to determine optimum temperatures for Chloride content

Challenge





16


Optimized process selectivity

Increased profits by an estimated 17%

Continue to use model for:

Process control

Offline optimization

Real-time optimization of the overall plant





17


Rapid and Easy Custom Modeling with Aspen Custom Modeler Hitachi Zosen

Required 99.5% purity ethanol to blend with gasoline

Needed a way to model and optimize the process

Required precise calculations of outlet streams

Physical property data played a key role

Considered zeolite membrane as an alternative to traditional dehydration methods

Ref: Masashi Okada, Tadayoshi Shimada

Hitachi Zosen Corporation



18

Solution Result

Modeled zeolite membrane with Aspen Custom Modeler

Physical property capabilities provided consistent data

Model can be studied in dynamic mode

Used Aspen Process Economic Analyzer to study cost effectiveness for integrated distillation column and membrane unit

Challenge






19


Total cost reduction of 18% estimated

20% reduction in CAPEX*

17% reduction in OPEX

Considered a variety of cases to optimize: investment, utility, and maintenance costs

Modeled complex units with ACM to open up new design possibilities

*CAPEX calculated on an annual basis
