Patent number: 10173166Abstract: A method of operating a carbon dioxide recovering apparatus includes introducing flue gas into an absorbing tower, bringing the flue gas into contact with an absorbing solution, and discharging a first rich solution, which is then divided into second and third rich solutions. The second rich solution is heated using a lean solution from a releasing tower. The third rich solution is heated using steam from the releasing tower. The lean solution and the steam are generated in the releasing tower from the second and third rich solutions. The steam used to heat the third rich solution is separated, in a gas-liquid separator, into carbon dioxide and condensate water. The amount of condensate water formed in the gas-liquid separator is measured, and a flow dividing ratio between the second rich solution and the third rich solution is controlled based on a change in the amount of the condensate water.Type: GrantFiled: June 16, 2016Date of Patent: January 8, 2019Assignee: Kabushiki Kaisha ToshibaInventors: Satoshi Saito, Hideo Kitamura, Mitsuru Udatsu, Toshihisa Kiyokuni
