Abstract
A CO2 recovery system includes an absorption tower that receives CO2-containing gas and CO2-absorbing solution, and causes the CO2-containing gas to come in contact with the CO2-absorbing solution to produce CO2 rich solution, and a regeneration tower that receives the rich solution and produces lean solution from the rich solution by removing CO2 from the rich solution. A heating member is provided in the regeneration tower. The heating member heats the rich solution in the regeneration tower with steam generated when regenerating the rich solution in the regeneration tower.
