Transforming the way industry designs and operates

PSE's gPROMS Advanced Process Modelling software and related services are transforming the way the chemical process industries design and operate plants.

gPROMS ProcessBuilder's combination of high-fidelity reactor and separation models and advanced optimisation techniques make it possible to dramatically accelerate next-generation process design and identify millions of dollars from 'already-optimised' processes.

PSE's laboratory-to-operating-plant approach helps optimise design and operation, reduce time-to-market and risk for new process development, and minimise capital and operating cost.

The downstream value chain

PSE's capabilities cover the entire downstream process application space – from refining to polymer manufacture – with a single steady-state and dynamic process modelling environment, gPROMS ProcessBuilder.


We bring powerful new technologies for 'desktop' optimisation of CDU operation and dynamic simulation of crude transition


Whole-plant optimisation and online monitoring of yield prediction and coking bring significant economic benefits to 'already-optimised' olefins plants

Intermediates & Derivatives

PSE has world-leading technology for optimising reactor design and operation in the context of whole-plant optimisation


Our polymers approach is based on high-fidelity population balance models to provide accurate molecular weight distribution (MWD).

Many other specific applications

PSE tools provide advanced process modelling capabilities for many key Chemicals & Petrochemicals process operations. Some examples are:

Advanced catalytic reactor design

Advanced reaction modelling technology makes it possible to design detailed reactors and include these in whole-plant flowsheet optimisations.
This means that you can optimise process designs taking all relevant interactions into account.

State-of-the-art separation models

ProcessBuilder provides state-of-the-art capabilities for steady-state and dynamic equilibrium distillation, rate based separation, pressure-swing adsorption, membrane separation and hybrid separation.

Solution crystallization

PSE provides unique capabilities for design, scale-up and operational optimisation of batch and continuous crystallization processes, including recipe optimisation.

Solids process modelling

PSE's unique capabilities for batch, continuous and semi-batch solids process operations use high-fidelity rigorous models to optimise design and operations.

Cyclic separation processes

The power of the gPROMS environment allows easy solution of complex complex separation processes such as pressure-swing adsorption.

Compression systems

ProcessBuilder's extensive compressor libraries allow accurate design of multi-stage equipment, surge analysis and other compressor design and operational analysis based on high-fidelity dynamic models incorporating manufacturers' curves.

Utilities and water treatment

In addition to the process-related capabilities described above, PSE provides extensive capabilities for utilities, including water treatment.

Utilities optimisation

gPROMS UtilitiesOptimiser is aimed at optimising the economic operation of refinery and chemicals plant utilities operations, taking into account the availability of, demand for and prices of steam, gas and other fuel.

Water treatment

Our extensive libraries of high-fidelity biological and physico-chemical wastewater treatment process models allow optimisation of design and operations as well as troubleshooting of treatment plants.
