A new scientific publication based on research from the AURORA project has just been released in the journal Industrial & Engineering Chemistry Research. This study delivers an in-depth analysis of the degradation behaviour of the CESAR1 solvent —a popular choice for solvent-based post-combustion CO₂ capture.This work, developed under the AURORA…

Abstract Global warming is a major issue that needs to be addressed and limited. The CESAR1 solvent blend has a high potential for becoming a commonly employed, commercial solvent system. In this work, the viscosity and density data for aqueous CO2 loaded CESAR1 (26.6 wt.% AMP 12.8 wt.% PZ) solution…

The final step in capturing and storing carbon dioxide (CO₂) emissions is geological storage, where CO₂ is injected deep underground into carefully chosen locations. These locations could be natural formations like saline aquifers (underground reservoirs filled with salty water) or empty oil and gas fields.This work, part of the AURORA…

The fight against climate change requires innovative solutions, and one promising method is CO₂ capture and storage (CCS). CCS involves capturing carbon dioxide from industrial emissions before it reaches the atmosphere. At the heart of this process are specialized chemical solvents, such as CESAR1, which absorb CO₂ from flue gases.While…

CO2 capture technology is vital for reducing greenhouse gas emissions. But what happens when the chemicals used in this process wear out or degrade? Scientists have been studying how to rejuvenate these chemicals through a method called thermal reclaiming. This research focuses on ethanolamine (MEA), a widely used solvent for…

AURORA’s latest scientific journal publication provides experimental density and viscosity data on different unloaded and CO2-loaded aqueous blends of  2-amino-2-methyl-1-propanol (AMP) and piperazine (PZ) used for absorption-based CO2 capture. The paper also provides correlations for density and viscosity suitable for various modelling works.In our previous review article, we identified knowledge…

AURORA latest review paper, developed in collaboration with researchers from SINTEF and NTNU, provides a comprehensive analysis of the CESAR1 solvent system. It collects and evaluates existing experimental data, highlights knowledge gaps, and outlines the necessary next steps in research to optimize the use of CESAR1 for CO₂ capture.In the…

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.Researchers have developed and tested advanced methods to control…

Abstract Reducing carbon dioxide (CO2) emissions is a significant global challenge in combating climate change. Chemical absorption using aqueous amine solution is the most mature technology for post-combustion carbon capture [1]. An aqueous blend of 3 M 2-amino-2-methyl-1-propanol (AMP) + 1.5 M piperazine (PZ), also known as CESAR1, is considered…

Abstract Growing global temperatures and human population lead to a constant increase in energy demand (Smit et al., 2014). Even with the growing energy supply from renewable sources, consumption of fossil fuels is inevitable in the future (Khaleel et al., 2022). Therefore, we should focus on technologies tackling CO2 emissions…

Abstract Chemical absorption using a blend of 3 M 2-amino-2-methyl-1-propanol (AMP) and 1.5 M piperazine (PZ) has gained attention due to its low energy demand and high degradation resistance. However, solvent emissions remain one of the major challenges to its industrial-scale application. Solvent emissions, in particular amine aerosol emissions, need…

Abstract CO2 capture using amine-based absorption is the most mature technology to decarbonize carbon intensive industries, Bui et al. (2018). Research has been focused on studying solvents that are stable, environmentally sustainable and energy efficient. The CESAR1 solvent, an aqueous blend of 3 M 2-amino-2-methyl-1-propanol (AMP) and 1.5 M piperazine…

Abstract CO2 capture plays a fundamental role in achieving the climate change goals set by the Paris Agreement 2015. Capturing 90% of the CO2 being emitted from industrial sources is not enough, (Brandl et al., 2021). There is a need to design, optimize and qualify technologies that achieve higher capture…

Abstract Many large-scale capture plants will need to be operated in a flexible and dynamic manner to cope with varying flow rates and/or CO2 concentration in the flue gas from the host plant. Under such circumstances, careful design of the capture plant is required, as well as proper process control…

Abstract The CESAR1 solvent is possibly the most popular non-proprietary solvent blend for CO2 capture and has been under thorough investigation in the past decade (Benquet et al., 2021; Buvik et al., 2024a; Campbell et al., 2022; Hume et al., 2022, 2021; Moser et al., 2023, 2021a, 2021b). The Horizon…

A chemical mixture called CESAR1 is being widely studied as a solvent to capture carbon dioxide (CO₂) from industrial emissions (like power plants). CESAR1 is made up of two chemicals: AMP (2-amino-2-methyl propanol) and PZ (piperazine). It’s more stable and degrades less over time compared to another common solvent called…
