Carbon capture

På svenska

Absorption of carbon dioxide occurs in several processes. In the production of biogas or synthetic natural gas from biomass, carbon dioxide must be removed from the produced gas before it can be used as a vehicle fuel or injected into the natural gas network. In the chemical industry, there is often a need to separate carbon dioxide from gas streams.

Carbon dioxide capture can also be used for Carbon Capture and Storage (CCS) in industrial processes and for power and heat production.

Carbon dioxide capture by absorption is an energy-intensive process. By reducing the energy demand, several processes can become more energy and cost efficient.

Research on carbon dioxide absorption at the Division of Chemical Engineering focuses on developing new and energy-efficient carbon dioxide absorption systems. This enables the use of excess heat in the process, which significantly reduces the cost. Research on existing carbon dioxide absorption systems is also conducted with the aim of developing processes that require less energy.
