Software Collaboration Project to Reduce CCS Costs

Thursday, December 22, 2016

TCM has long worked to reduce the cost of carbon capture. This project will contribute further to this, by automating more of the operations, says Managing director Roy Vardheim.

Plant automation is based on model predictive control (MPC), commonly used in other industries such as oil refining and petrochemicals. MPC is an overarching regulating system that can read plant data and calculate the optimum set point basis regulators.

The MPC technology to be used in this project was developed by Cybernetica, NTNU and SINTEF and Cybernetica will assist with the practical implementation at Tiller and TCM. The dynamic process model that becomes part of the tool has been developed in the doctoral thesis of Nina Enaasen Flø now working for TCM.

- It is very nice that the tool is put to use, and I'm excited to see if we meet the goals for reduced energy consumption. Test facilities are often shut down and restarted, and then it's much to be gained from such automation, says Flø. With this tool one can move faster from one test run to another, have more effective test campaigns, more efficient operations and thereby reduce energy consumption by 3-5 percent. The tool compares estimates from the model with actual process measurements in the plant and makes corrections if necessary. Especially when changing parameters it is much to gain from automation.

The project represents a continuation of the good working relationship between TCM and CCS environment in Trondheim.

TCM will contribute to the project with MEA test result data and access to testing by TCM during the MEA campaign scheduled for Q3 2017. Before that the tool will be tested in SINTEF's pilot plant at Tiller in Trondheim. Hanne Kvamsdal from Sintef is project leader for DOCPCC.

The dedicated DOCPCC test in the amine plant is expected to last about 1-2 weeks, while the remaining testing will be conducted as parallel activities to other MEA campaign activities.

CCS technologies will in future compete with renewable energy sources like wind, solar, etc., and low OPEX for CCS facilities and projects are essential to be considered competitive to these. (TCM)
