Cybernetica develops, implements, commissions and maintains solutions for model-based control, supervision and optimization of industrial processes. Delivering software applications for advanced process control, providing systems and long-term services, Cybernetica is a partner for excellence in process operations. We are 12 employees, situated in Trondheim, Norway.

Future Cooperation with TCM
We have experienced enthusiasm from both TCM employees and visiting researchers during the tests, which reinforce our impression that the technology is promising. We are discussing cooperation with TCM in a potential extension of the MEA-4 campaign, but it’s currently just in the early planning phase.

Why did you participate in this test?

Cybernetica was one of the partners of the DOCPCC project in 2016-2017, which was extended into DOCPCC 2 for 2018. Both project phases included several weeks of live testing on TCM. Installation of Cybernetica’s tool for Nonlinear Model-based Predictive Control (NMPC), Cybernetica CENIT, was a crucial part of both projects. Cybernetica was monitoring and supervising the tests on-site, working together with plant personnel at TCM.

Briefly describe your project on TCM

DOCPCC has been oriented around model-based approaches for more efficient amine-based CO2-capture, through automation and control. Among the goals is to automatically fulfil the required targets for CO2 capture while rejecting process disturbances such as flue gas variations, for instance. In essence, Cybernetica CENIT aims to control the capture ratio in an energy optimal way. To test this in live operation, rather than just doing simulated studies, was crucial.

What has your contribution been?

Cybernetica has been working with model development and model refinement in DOCPCC. That means deploying and adapting mathematical process models to be numerically efficient and suited for use in online tools on TCM. The models have been used as key components in process control software, also developed and implemented by Cybernetica. To design and implement these software components has been the task of Cybernetica, including controller configuration and tuning. A main challenge has been the combination of an optimizer application, based on possible energy cost changes during a 24 hour period, combined with “Minute to minute” process control.

Which results are you most proud of?

We have successfully demonstrated that the control system can reside at the required capture rate while rejecting process disturbances. In essence, it’s an efficient supporting tool to the operators in the sense that it can relieve the operator some of the duties (i.e. micromanagement of operating conditions) to focus on other things. Additionally, we have demonstrated that the software can do so in an energy efficient manner, thus contributing to the very central topic of cost reduction.

TCM’s importance to your results

  1. What would you emphasise as TCM’s three main benefits as a test arena?
  • People: Professional and well-organized. Skilled operators together with helpful plant engineers contribute to a nice arena for introduction and testing of new technology.
  • Plant equipment: Well-functioning, high-quality process equipment gives a good basis for advanced tests. Abundance of instruments and measurements, together with good IT infrastructure, is nice for automation and control testing.
  • CO2-capture community: TCM has a wide range of owners, customers and contributors, and TCM is a well-established center of attention in the industry. As a newcomer in the industry (like Cybernetica is), it’s a very useful arena to test and showcase technology.

Where are the results shared

Our results are reported to Gassnova at every milestone, as detailed technical reports. In addition, results are presented at conferences (PCC4-2017, GHT14-2018) , in journal papers (Computers and Chemical Engineering) and web pages (Climit, TCM, Cybernetica).
