gPROMS Process: Process simulation for the digital age

gPROMS Process is a next-generation process modelling environment that supports the entire concept-to-operations process design cycle. With advanced analysis and optimization technologies operating on high-fidelity models, gPROMS digital process twins help accelerate process design, quantify and manage risk, and determine optimal process designs that generate value over the lifetime of the plant.

Key deciding factors for us were the sophistication of the gPROMS modelling products and the single integrated platform

gPROMS Process at-a-glance

gPROMS Process provides all the functionality of first-generation process simulators – plus many powerful next-generation capabilities – within a single, unified environment.

Key benefits: Better processes, faster and at lower cost

The benefits of digital process design can be summarised as “better processes, faster and at lower cost”. It enables you to:

  • accelerate process innovation
  • reduce time-to-market for new processes
  • reduce experimentation and pilots
  • perform rapid and effective exploration of the decision space and systematic quantification of risk
  • truly optimize the process design for maximum lifetime profit

Support for the digital process design cycle

gPROMS Process is the first process modelling environment specifically designed to support a digital design approach, from early-stage R&D to plant commissioning. State-of-the-art tools within the process industries’ most powerful modelling and optimization environment provide a 21st century experience that delivers value well beyond that achievable with traditional flowsheeting simulators.

Key features & advantages

Digital process design is “process simulation for the digital age”. It enables rapid exploration of the decision space and accurate quantification of risk using validated high-fidelity models, to arrive at the optimal process design rapidly and systematically.

gPROMS Process supports the digital process design approach every step of the way:

gPROMS Process is the first general-purpose modelling environment to support all the key stages and activities of digital process design:

  •  Construction of digital process twins using industry-leading high-fidelity models
  •  Calibration against experimental or plant data using state-of-the-art parameter estimation and model validation tools
  •  Global system analysis for rapid exploration of the decision space and quantification of risk
  •  Multivariate optimization to determine the optimzal solution.

gPROMS Process contains a wide range of general process and process-specific models. Key libraries include:

  • all standard process models – heat exchangers, distillation and so on – for basic process modelling
  • Advanced reactor models – high-fidelity catalytic, thermal cracking and electrochemical reactor models, for rapid and confident design of complex processes
  • Adsorption – industry leading adsorption models for fast and robust solution of cyclic separation processes
  • Hybrid data driven models – in cases where the physics or chemistry are not sufficiently defined, these can be combined with data-driven models to create hybrid first-principles – data models.
  • Specialist process-specific models – LNG exchangers, olefins cracking furnaces, polyolefins reactors, and so on.

gPROMS Process can be used with a wide range of property packages. However the built-in (default) gPROMS Properties is a leader in its field.

A key feature of gPROMS modelling environments is the ability to create high-fidelity custom models of processes to capture corporate knowledge and create competitive advantage.

You can easily create and maintain custom models using all the power of the gPROMS® platform’s advanced process modelling language – with no need for programming. Models can then be published in libraries for other users across the organisation.

Models can be validated against laboratory, pilot or operating data to fit empirical constants such as reaction kinetic parameters and heat transfer coefficients using gPROMS’s state-of-the-art parameter estimation capabilities.


Utilising corporate knowledge to create competitive advantage

The custom modelling capability enables you to:

  • create novel process units with novel configurations where suitable standard library models might not exist
  • create your own corporate model libraries
  • take advantage of existing investment in legacy models by moving them to a modern, maintainable platform
  • include more detail than is contained in the standard library models
  • create your own industry-specific flowsheeting simulator.

Digital Applications: supporting operational excellence

Following commissioning, gPROMS Process digital twins containing deep process knowledge can be implemented on the operating plant, connected to real-time data.

Such Digital Applications for Operations are used to generate value daily through advanced process monitoring, soft-sensing, real-time optimization, what-if-analysis and other advanced process control (APC) and decision support applications.
