A carbon dioxide capture system according to an embodiment includes: a carbon dioxide capturer, an absorbing liquid regenerator, a first washer, a second washer, and an absorbing liquid line. The first washer washes the combustion exhaust gas discharged from the carbon dioxide capturer with a mist of a first cleaning liquid sprayed by a first spray to capture the amine accompanying the combustion exhaust gas. The absorbing liquid line supplies the absorbing liquid regenerated in the absorbing liquid regenerator as the first cleaning liquid to the first spray. The first cleaning liquid sprayed by the first spray is supplied as the absorbing liquid to the carbon dioxide capturer.

Carbon dioxide capture system and method of operating carbon dioxide capture system

According to one embodiment, an amine-containing water concentration system includes an osmotic pressure generator and a carbon dioxide introducing unit. The osmotic pressure generator includes a treatment vessel, a first chamber to which the water to be treated is supplied, a second chamber capable of storing a working medium, and a semipermeable membrane that partitions the first chamber and the second chamber, which are located in the treatment vessel. The carbon dioxide introducing unit is capable of introducing carbon dioxide into the water to be treated.

Amine-containing water concentration system and apparatus, and carbon dioxide recovery system

According to one embodiment, a gas processing equipment includes an oxygen removerthat removes oxygen contained in exhaust gas G, and a gas processing devicethat processes pretreated exhaust gas G (P), from which the oxygen has been removed by the oxygen remover, with a carbon dioxide absorbent solvent S as a treatment agent.

Gas processing equipment and gas processing method, and carbon dioxide capture system and carbon dioxide capture method

According to embodiment, a carbon dioxide capturing system cools a regenerator discharge gas discharged from a regeneratorcontaining carbon dioxide by a cooling unit, and then sends the gas to a cleaner. The cleanerreceives condensed water generated from the regenerator discharge gas cooled by the cooler, and a gaseous cooled regenerator discharge gas, and cleans the cooled regenerator discharge gas by a cleaning liquid. The cleanerhas a first liquid reservoirconfigured to store the condensed water, and a second liquid reservoirconfigured to store the cleaning liquid having cleaned the cooled regenerator discharge gas.

Carbon dioxide capturing system and operation method thereof

In one embodiment, a carbon dioxide capturing system includes an absorber to absorb CO2 from first gas into lean liquid, and produce rich liquid that is the lean liquid absorbing the CO2 and second gas that is the first gas removing the CO2, and a regenerator to separate third gas including the CO2 from the rich liquid flowing from the absorber, and provide the lean liquid and the third gas. The system further includes a flowmeter to measure a flow rate of the third gas, a liquid level gauge to measure a liquid level of the lean liquid and/or the rich liquid, and a controller to regulate a quantity of heat energy supplied to the regenerator based on the flow rate of the third gas, and regulate a total amount of the lean liquid and the rich liquid in the system based on the liquid level.

Carbon dioxide capturing system and method of operating the same

A carbon dioxide capture system according to an embodiment includes a carbon dioxide capturer, a first washer, and a second washer. The first washer includes a spray configured to spray first cleaning liquid supplied under first pressure. The second washer includes a cleaning liquid diffuser configured to diffuse and drop second cleaning liquid supplied under second pressure lower than the first pressure.

A carbon dioxide capture system includes: a washing unit which uses cleaning water to clean absorption unit exhaust gas or stripping unit exhaust gas; and a gas-liquid separation device which allows condensed water generated by cooling washing unit exhaust gas to be separated from the washing unit exhaust gas. The condensed water is mixed into the cleaning water by a condensed water line. If the amount of the cleaning water becomes more than a predetermined amount, the cleaning water is mixed into an absorbing liquid by a cleaning water line. A controller controls a condensed water valve.
