The removal of carbon dioxide from flue gas is one of the most important issues for preventing a greenhouse effect. An alkanolamine in aqueous solution absorbs CO2 and is regenerated by CO2 recovery in the temperature range from 100 to 120 °C. In order to obtain the energy for CO2 recovery, we are studying for solar energy utilization as a heat source for CO2 recovery process. This temperature range can be obtained using a stationary trough-type concentrator. We designed and fabricated CO2 recovery system which consists of an integrated stationary evacuated concentrator and an amine regenerator. CO2 was successfully recovered using this system, and the system performance and properties of amine regeneration process were evaluated. The solar collecting area required for CO2 recovery was also evaluated.
