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
|
5
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
|
6
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

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

Challenge
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
|
15
Challenge
Result
Solution
 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

Rapid and Easy Custom Modeling with Aspen
Custom Modeler
Hitachi Zosen
Challenge
Solution
Result
 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

Custom Modeler
Hitachi Zosen
Challenge
Result
Solution
 Total cost reduction of
18% estimated
 20% reduction in CAPEX*
 Considered a variety of cases
to optimize: investment,
utility, and maintenance costs
Total Cost
 17% reduction in OPEX
 Modeled complex units with
ACM to open up new design
possibilities
*CAPEX calculated on an annual basis
