ALIGN-CCUS (Accelerating Low CarboN Industrial Growth through Carbon Capture Utilisation and Stor... more ALIGN-CCUS (Accelerating Low CarboN Industrial Growth through Carbon Capture Utilisation and Storage) is a project supported by the ERA-NET Co-fund ACT program. In the first call of this program nine European countries, together with the European Horizon 2020 program have joined forces by making funds available for research and innovation actions related to carbon dioxide (CO2) Capture,Storage and Utilisation (CCUS). The participants of ALIGN-CCUS project represented the ERA-NET ACT countries of The Netherlands, Germany, Norway, Romania and the United Kingdom. The ALIGN-CCUS consortium involved 30 partners from industry, research and academia and has considerable involvement of industrial companies and enterprise organizations. The industrial partners not only supported the research but also committed to directly invest and participate in the R&D and demonstration activities in the project, boosting the credibility of the project’s potential for accelerating and maturing CCUS technologies. The project has ended in November 2020 and its results are already being used in various CCUS projects around the globe. More than 100 reports have been produced, of which 57 are public and available from our website www.alignccus.eu. Many detailed results will be presented at conferences and in other papers. In this paper a high-level overview is given of the research performed in ALIGN-CCUS and its immediate impact in the CCUS community.

Considering cycle efficiency and given similar computational assumptions, the Graz-cycle and the latest versions of the Matiant-cycle seem to give rather similar efficiencies, while the Water-cycle is 3-5%points behind. The Water-cycle is a Rankine-type cycle, while the Graz-cycle is a mixed Brayton/Rankine cycle, and the more recent Matiant-cycle is a combined topping/bottoming Brayton/Rankine cycle. Generally, Brayton cycles, in combination with Rankine cycles, exhibit higher efficiencies than Rankine cycles alone. The thermodynamic explanation for this is that Brayton cycles combined with Rankine cycles have a higher ratio of the temperatures at which heat is supplied to, and rejected from, the cycle, compared to that of a Rankine cycle. According to the Carnot cycle efficiency definition, the efficiency is improved when this temperature ratio increases.

The test campaign included transient step responses in steam, exhaust gas, solvent flow rate and in exhaust gas CO2 concentration. In addition, a test with simultaneous steps in all flow rates (exhaust gas, solvent and steam) was included. A dynamic model of the Heilbronn plant was then implemented in the dynamic simulator K-Spice® and tested against the step responses at the plant. In spite of some stead state deviations, the model was able to capture the process dynamics very well. For dynamic studies one can therefore assume that the model is representative for the plant. In the work presented here, two different control configurations were tested: 1) Ratio control in combination with a slow feed back control on the CO2 out of the absorber and 2) Control of CO2 out of the absorber by lean liquid flow rate and a temperature sensor up in the desorber packing. Both structures involve only simple PID control loops and are thus easy to implement. The proposed control configurations were tested by simulations with 30% changes in flue gas flow and composition. Both configurations showed good performance during the simulation testing, but the second one was superior as well as excellent with respect to tight CO2 recovery control. This may be an important property in supervisory control schemes.

RateSep is the second generation rate-based model in AspenPlus. Because of the phenomena of combined absorption and water vaporization and condensation, a temperature bulge will appear in the absorber. The present study addresses the effects of column
