  • Patent number: 9901862
    Abstract: A carbon dioxide recovery system includes an absorption tower in which carbon dioxide is absorbed into an absorbing solution then the absorbing solution is output to a regeneration tower in which carbon dioxide is released from the absorbing solution. The regeneration tower outputs the absorbing solution from which carbon dioxide has been released and an exhaust gas included released carbon dioxide and water vapor. In a condensing section the exhaust gas is separated into dioxide gas stream and a condensed water stream. In a mixing section the condensed water is mixed with an amine to a replenishment amine aqueous solution in which the amine is dissolved in the condensed water. In a replenishment section the absorbing solution is mixed with the replenishment amine aqueous solution.

  • Publication number: 20160296880
    Abstract: 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.
