Mini-pilot for solvent performance evaluation in carbon capture

Advances in amine-based carbon capture technologies largely depend on solvent formulation. The optimal formulation is yet to be found and the topic still needs studying.

Carbon capture, utilization and storage (CCUS) is reviewed as an important technology for reducing greenhouse gas emissions. Carbon emissions originate from various industries each with different concentrations of CO2 e.g. 4 vol% from iron and steel facilities, 12 vol% from power plants, 33 vol% from cement and 40 vol% biogas.


Amine-based carbon capture is one of the more mature technologies for capturing CO2 from low concentration sources. However, there is still a lot of potential for improving the formulation of the amine solvent. To evaluate the performance of new solvents, it is important to have a baseline for comparison.


In this project, we aim to test and investigate the performance of solvents using a new mini-pilot setup. The solvents will be benchmark in a pilot with a capacity to treat up to 2 kg CO2/h with a liquid flow of 15 kg/h. The performance of the new solvents are compared to an existing base case solvent e.g. 30 wt% MEA. The scale of the mini-pilot allows for conducting CO2 capture experiments on a comparable basis and allows for testing of alternative configurations of the carbon capture process.
