Advanced Model Libraries

High-fidelity predictive models

AML Gas-liquid contactors

PSE's AML for Gas-Liquid Contactors (AML:GLC) can be used for rate-basd modelling of almost type of separator

In addtion to the gPROMS advanced process modelling framework, PSE provides Advanced Model Libraries (AMLs) of high-fidelity predictive models specific to various domains.

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 multicomponent diffusion between bulk liquid and catalyst surface.
They model both steady-state and dynamic behaviour.
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.

Note that PSE has many other high-accuracy models available that are not yet provided within a library framework. Please contact us if you are looking for a model for a particular application

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 accuracy in modelling of shell and tube temperature profiles.

AML:FBCR — for Fischer-Tropsch

This is a version of the AML:FBCR specially tailored to handle the complex Fischer-Tropsch reaction.

While considered as a part of the fixed-bed reactor libraries, much of the functionality embedded in the AML:FBCR/FT is applicable to other forms of Fischer-Tropsch reactor, such as slurry phase and bubble column reactors.

AML:GLC — Gas-Liquid Contactors

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.

AML:FC — Fuel cells

Fuel Cells (see also gFuelCell)

The AML:FC is a library of high-fidelity modelling components for fuel cell component and system design.

In addition to providing state-of-the-art component models, it can be used in conjunction with the standard gPROMS Process Model Library (PML) models to construct system flowsheets.

The optional gPROMS-CFD Interface (Fuel Cell Stacks) can be used to link the gPROMS electrolyte/membrane model with a CFD model of the air and fuel channels.

AML:PRS — Pressure Relief Systems

See gFLARE

Licensing terms and conditions

The gPROMS AMLs are available under similar annual licensing arrangements to other gPROMS components.

A five-day specialist training course is included in the price of certain libraries. Please contact PSE sales for more information.

Open Models

By default AMLs are supplied in 'customisable' form. This means that you have access to the key areas where customisation is typically required – for example, reaction rate equations.

It may be possible in certain circumstances, for a premium, to purchase open model versions of the libraries. These are supplied under corporate-wide licence at PSE's discretion.
