Advanced Model Libraries
PSE has an expanding portfolio of libraries of high-fidelity gPROMS models for specific application areas, known as the gPROMS Advanced Model Libraries (AMLs):
The key benefit of the AMLs is that their unprecedented accuracy provides high-value information for decision support in all areas of process design and operation.
Characteristics of the AMLs are that:
- They represent the state-of-the-art for modelling in their application area.
- They contain models of unprecedented accuracy and level of detail - for example, catalytic reaction models that take into account diffusion between bulk liquid and catalyst surface.
- They model both steady-state and dynamic behaviour.
- They are available in open model form, meaning that you can inspect and customise the defining equations (see below).
- They can interact with Computational Fluid Dynamic (CFD) models where it is necessary to take detailed hydrodynamic effects into account - for example, in modelling of scale-up for crystallisation processes.
- They are capable of being used in a wide variety of different process sectors - from pharmaceuticals and fuel cells to petrochemicals and refining.
- Because of their accuracy, they can be used from design of laboratory experiments to online applications, and for a wide range of process conditions.
Advanced Model Libraries
The following AMLs are available:

AML:FBCR — Fixed-bed Catalytic Reactors
The AML:FBCR is used for modelling reactors with any type of fixed catalyst bed configuration — for example, tubular or multitubular reactors.
For multitubular configurations, the Hybrid Multitubular interface can be used to link gPROMS tube models to a CFD model of the shell-side fluid for unprecedented modelling of shell and tube temperature profiles
-

AML:SC — Solution Crystallisation
The AML:SC is used for modelling complex solution crystallisation processes — for example, in sugar, lactose or terephthalic acid production.
For enhanced accuracy the Hybrid Multizonal interface can be used to integrate CFD hydrodynamic data within gPROMS well-mixed zone models

AML:GLC — Gas-Liquid Contactors
The AML:GLC is a library of components for non-equilibrium modelling of packed column separation processes.
Virtually any type of column can be modeled, from conventional packed columns for distillation, absorption and evaporation, to more complex units such as heat-integrated distillation columns, dephlegmators and falling-film columns.
Open Models
PSE adheres to open model principles.In contrast with other vendors, all of our model libraries, including the Process Model Library (PML) supplied with standard gPROMS, are provided in open-source form. This means that you can inspect the relationships contained in all AML models, and modify them as required.
This puts you in control of the information used to make critical design and operational decisions. Furthermore, it means that you can use models to capture valuable corporate knowledge and transfer it across the organisation.
Licensing terms and conditions
The gPROMS AMLs are available on a perpetual, corporate-wide license on payment of a one-off fee in advance. Optional maintenance and update service applies after the first year.
A five-day specialist training course is included in the price of certain libraries. Please contact PSE sales for more information.
Making advanced model applications available to other model users
… within flowsheeting packages, using gO:CAPE-OPENAny model built using PSE AMLs (with the exception of models incorporating CFD links) can be implemented within any CAPE-OPEN simulation environment — for example, Aspen Technology's Aspen Plus or SimSci's PRO/II. |
… to control engineers, using gO:MATLAB and gO:SimulinkHigh-fidelity reactor, crystalliser or packed column models can be exported to the Mathworks MATLAB ® or Simulink ® environments, where they are executed using the gO:MATLAB and gO:Simulink gPROMS Objects. This enables control engineers to design and test control schemes using the same high-fidelity models as used in process and detailed equipment design. |
… to operations personnel, using gO:RunLikewise, you can make sophisticated plant models available for decision support to operations, purchasing and other "non-modelling" personnel, behind an Excel or other custom-built interface. |
ModelCare
PSE's ModelCare service is available to help with implementation of your advanced model. PSE's Consultants have extensive expertise and experience in creating custom models for complex applications.
