This publication, prepared by our project partners Cybernetica and SINTEF Industry, is a proceeding from the 34th European Symposium on Computer Aided Process Engineering and the 15th International Symposium on Process Systems Engineering (ESCAPE34/PSE24), held in Florence, Italy, from June 2-6, 2024.
Solutions for advanced control of CO2 capture processes have been developed and tested on pilot scale, with full-height absorber and desorber columns, representative of operation on an industrial scale. This paper presents new results from live demonstrations of non-linear model predictive control (NMPC) in pilot scale, using the HiPerCap solvent HS3 on the SINTEF Tiller CO2LAB pilot, including ongoing work in the AURORA project, to build on the established results in this field, hereunder published case studies and pilot demonstrations.
The results indicate that industrial deployment of NMPC for solvent-based CO2 capture processes is imminent, and that it will constitute a valuable tool to automate the operation. The demonstrated outcome for the end-users is energy-optimal operation handling all operating conditions, with less operator interventions. Furthermore, the approach has possible extensions to combat advanced operational challenges.
Conference abstract – GHGT-17: “Storage potential evaluation of eastern Mediterranean area as final step of the full chainassessment”
The last step of the CCUS full chain is represented by geological storage, when the CO2 is injected, via injection wells, into the deep sub-surface at a carefully selected site (such as a saline aquifer or a depleted oil/gas field). This work describes the methodology and the results adopted by…
Conference abstract – GHGT-17: “CESAR1 solvent degradation in pilot and laboratory scale”
The non-proprietary CESAR1 amine blend has been widely studied for use as a solvent for post-combustion CO2 capture. 1–5 Despite of its relative popularity in the solvent market, there are still many knowledge gaps connected to the stability of CESAR1. The mixture of 2-amino-2-methyl propanol (AMP, CAS 124-68-5) and piperazine…

Abstract – PCCC-7: “The impact of solvent degradation products on operation and environment”
Abstract Solvent degradation during the CO2 capture process is known to reduce capture capacity, increase corrosivity, emissions and solvent toxicity, and complicate operation of the plant. The wide variety in degradation compounds include charged species, typically referred to as heat stable salt (HSS), amides, acids, nitrosamines, small volatile organic compounds,…
Abstract – TCCS-12: Kinetics of the Absorption of CO2 into aqueous loaded solutions of AMP and AMP/PZ
Abstract Amine-based absorption is currently the most advanced and cost-effective means of postcombustion CO2 capture among the different technologies that can be used (Dutcher et al., 2015). Much work has been done to reduce energy consumption, which constitutes one of the major penalties to the absorption process. Therefore, when it…
Abstract – PCCC7: Development needs and knowledge gaps of CESAR1 solvent
Abstract The reduction of carbon dioxide (CO2) emissions is a major global challenge in the fight against climate change. Among the various technologies available for post-combustion CO2 capture, amine-based absorption is currently considered the most advanced and cost-effective[1]. However, the absorption process incurs a significant energy penalty, prompting research efforts…
Abstract – TCCS-12: Towards understanding CESAR1 degradation
A reason why aqueous ethanolamine (MEA) is still considered a benchmark solvent for CO2 capture by some, despite of its relatively high energy consumption and relative instability compared to other solvents, is the abundance of knowledge and public data on MEA performance and chemistry. With more than 50 identified degradation…
Abstract – TCCS-12: “AURORA – ACCELERATED DEPLOYMENT OF INTEGRATED CCUS CHAINS BASED ON SOLVENT CAPTURE TECHNOLOGY”
ABSTRACT AURORA is a three and a half year HORIZON Europe project funded by EU and kicked off in January 2023. The participants of AURORA represent the following six European countries: Norway (5 partners), United Kingdom (1 partner), Belgium (1 partner), France (2 partners), Italy (1 partner), and Greece (2…
