Advanced Process Modelling (APM)

Much more than process simulation

Advanced Process Modelling (APM) is a technology that uses high-accuracy predictive models of process equipment and phenomena to provide high-quality information for decision support in process innovation, design and operation.

The predictive power of an APM model results from the combination of first-principles chemical engineering, physics and chemistry with 'real-life' data such as laboratory, pilot plant or operational measurements.

gPROMS provides facities for all Advanced Process Modelling activities across the process lifecycle, from R&D through process and detailed design to online operation.

Typical applications

gPROMS is used to generate high-quality predictive information for:

Reactors of all kinds

Complex separation

Crystallisation processes

gPROMS is the leading Advanced Process Modelling environment for the process industries. It can be applied across many application areas in all process sectors.

gPROMS' process modelling, process simulation and optimisation capabilities are used to generate high-quality information for model-based decision support in process and product design and process operations.

It is applied by major process organisations throughout the world to to provide high-quality information for decision support in product and process innovation, design and operation.

There are also approximately 150 academic institutions worldwide using gPROMS for research and teaching, ensuring that gPROMS is constantly being applied to the most challenging applications in new areas of research.

gPROMS has many major advantages over other modelling systems on the market, resulting from its modelling power and the sophistication of the models possible.

gPROMS components

gPROMS is in fact a family of products rather than a single environment: the gPROMS ModelBuilder is used to build, validate and execute models, while the gPROMS Objects allow gPROMS models to be used within other engineering software.

gPROMS ModelBuilder

ModelBuilder is both a graphic flowsheeting environment for process engineers, and an advanced custom modelling environment for expert modellers.

It can be applied all the way from process or product development in the laboratory to support of online plant operations, by a wide range of users with different levels and areas of expertise.

ModelBuilder provides support at all stages of the model lifecycle: model construction, validation, execution and subsequent maintenance.

The gPROMS Objects

The gPROMS Objects wrap a gPROMS model – plus all the solvers and other gPROMS components required for its solution – in a form that can be embedded seamlessly within other popular engineering software environments such as Aspen PlusTM, PRO/II®, CFD packages and MATLAB®. gPROMS can also link to CFD software such as Fluent® in numerous other ways.

The gPROMS Model Libraries

gPROMS is not just a sophisticated modelling environment. The gPROMS Process Model Library and Advanced Model Libraries for reaction, gas-liquid separation and crystallisation.

PSE ModelCare

PSE recognises that creating high-accuracy process models requires expertise. That is why we provide the ModelCare service.

ModelCare aims to help companies deliver fit-for purpose modelling applications rapidly, while transferring modelling know-how to customer organisations.

What is gPROMS?

gPROMS is an equation-oriented modelling system used for building, validating and executing first-principles models within a flowsheeting framework.

In order to construct a model, the user writes down the fundamental chemistry, physics, chemical engineering, operating procedures and other relationships that govern the process or product behaviour.

The resulting model is then validated against observed data — typically, laboratory, pilot plant or operating data — to adjust model parameters such as heat transfer coefficients to match reality as closely as possible.

The first-principles approach combined with rigorous validation results in models of unprecedented accuracy.

gPROMS contains comprehesive error-checking and audit facilities to help in the construction of models. PSE also provides comphrehensive open model libraries and a modelling services to simplify and speed up model creation.

Once a model exists, it can be solved in many different ways to perform many different activities – for example, steady-state simulation, dynamic simulation, parameter estimation, model-based experiment design, steady-state and dynamic optimisation, including integer optimisation, or generation of linearised models for use in control and online optimisation, across the process lifecycle.

This provides multiple return on modelling investment, and ensures that models are used wherever they can generate value.

Who uses gPROMS and why?

gPROMS is used to generate high-quality predictive information for decision support in all aspects of design and operation, across all sectors of the process industries.

Typical application areas are those that involve complex physical and chemical phenomena, such as reaction engineering, crystallisation and complex separation processes.

gPROMS technologies can be applied in many different ways to address generic process challenges. There are many more examples of specific applications of APM in industry in the examples summary and in the application areas section.
