End-to-end high-fidelity whole chain systems modelling
gCCS is the commercial system modelling tool for whole-chain carbon capture & storage systems that will be released by PSE at the end of the CCS System Modelling Took-Kit Project.
gCCS operates like many standard process flowsheeting tools, but unlike these it contains high-fidelity models of all major CCS operations. In addition, powerful modelling and solution capabilities mean that it can be used for detailed steady-state and dynamic simulation and optimisation across large sections of CCS networks.
The diagram below shows a 'drill-down' view from a whole CCS chain model (left) into a pulverised coal and CCGT power station models (centre and right).
gCCS is built on PSE's gPROMS advanced process modelling platform, and inherits many of the platform's powerful capabilities. Key features are:
- High-fidelity models of all main CCS chain components with multicomponent streams, equilibrium and rate-based phase modelling
- Rigorous gSAFT physical properties
- Intuitive drag & drop flowsheeting environment
- Steady-state and dynamic simulation within the same environment
- Powerful solution capabilities, allowing simultaneous analysis of large sections of CCS networks with many recycles
- Optimisation – including mixed-integer and dynamic optimisation – capabilities, allowing economic optimisation with many decision variables
- Custom modelling capabilities, allowing easy creation of new process models
- Execution on multiple Windows and Linux platforms.
gCCS provides models for the whole CCS chain:
|Compression & transmission||Injection & storage|
It is possible to integrate standard PSE's offerings, such as air-separation unit (ASU) models, with the gCCS libraries.
Some typical applications of gCCS are to:
- Investigate flexible operation of a post-combustion capture plant attached to a coal-fired power station
- Optimise integration between the power plant and capture plant
- Design optimal compression trains for flexible service
- Investigate the effects of upstream or downstream changes in operation (for example, injection trip)
- Screen and rank economic alternatives
- Optimise design or operation based on an economic objective function.
gCCS will become commercially available at the end of March 2014. It is currently available to project participants and approved evaluators.
