We are delighted to announce gPROMS Process 2.0. Formerly known as gPROMS ProcessBuilder, gPROMS Process 2.0 is the first major release since PSE was acquired by Siemens, and its significantly enhanced capabilities and functionality reflect the substantial investment Siemens is making into product development.

The name change signifies a break with the past. Until now, ProcessBuilder has been an environment for sophisticated users who are typically running high-value, complex optimizations. This is the first release in a major, two-year development programme that will bring the next-generation capabilities of the gPROMS platform to a much wider range of users across process organisations.

What’s new?

We’ve been busy! Here are some of the innovations and enhancements you’ll find in gPROMS Process 2.0:

New model libraries and enhanced content

Version 2.0 contains significantly-enhanced model library content, including

  • a new polyolefins library to support online nonlinear control applications for polymers such as LDPE and HDPE
  • a new advanced model library for electrochemical reactors, for optimization of clean energy and hydrogen systems
  • data-driven model library for hybrid applications that combine data-driven elements with first-principles models
  • a batch distillation capability and new decanter model for specialty chemicals
  • enhancements to the multistream heat exchanger for LNG process optimization
  • enhancements to PSE’s industry-leading catalytic reactors model library
  • a unique new cyclic steady-state solver to speed up modelling of cyclic processes such as pressure swing adsorption.

gPROMS Properties

An all-new integral gPROMS Properties package covers a wide range of systems, including solid phases and reactive systems, plus complex compounds​ such as associating compounds​, polymers and electrolytes – all within a single properties package.

gPROMS Properties includes all standard thermodynamic models, plus PSE’s industry-leading SAFT-γ Mie, which allows accurate prediction of physical properties and phase behaviour even in situations where little or no experimental data is available.

A flexible software architecture allows easy addition of new models, plus interfacing of companies’ own models and parameter databanks. A wide range of flash calculation options and tight integration with gPROMS Process and the gPROMS core platform ensures robust and efficient solution of even the largest and most complex problems.​

gPROMS Properties is designed to be easily usable by experts and non-experts, with easy configuration of materials, management of databases and results visualisation​.

More power to the surrogates

gPROMS Process benefits from a number of new features in the underlying gPROMS platform:

  • An enhanced global system analysis (GSA) capability simplifies generation of fast-solving surrogate models, a capability that has already been extensively proven on very-large-scale, multi-site optimization projects and simplification of models of highly-complex processes such as fuel cells
  • A new interface to Siemens’ Computational Fluid Dynamics STAR-CCM+ product simplifies combining process and hydrodynamics models for detailed equipment design.
  • The new experiment data manager makes it much easier to manage experimental data sets during model validation.


Support for the gPROMS Web Applications Platform (gWAP) now makes it easy to supply models to ‘non-modelling’ users across the organisation via web interfaces.

The ability to execute sophisticated models from simple web interfaces opens up whole new categories of users and applications. Scientists, operations personnel, feedstock purchasers, salespeople and many others can now benefit directly from investment in model development without the need to know anything about the underlying models.

In addition, the ability to utilise cloud-based services such as Amazon Web Services (AWS) opens up access to virtually unlimited computing power for such applications.

More to come

And that’s not the end. Watch out for announcements of further developments in the next few months!
