요약

A CO2 recovery device includes: a CO2 absorption tower in which CO2 included in an exhaust gas is absorbed by a CO2 absorption liquid; and a CO2 absorption liquid regeneration tower that heats and regenerates the CO2 absorption liquid that has absorbed CO2. The CO2 absorption liquid regeneration tower includes: a main body part in which the CO2 absorption liquid is temporarily stored; a boot part provided downward from a tank end of the main body part, having a relatively smaller capacity than the main body part; a flowmeter provided to the boot part, and measuring the liquid surface level of the CO2 absorption liquid that changes between the main body part and the boot part; and a control device controlling the liquid surface level of the CO2 absorption liquid between the main body part and the boot part on the basis of the measurement result of the flowmeter.

대표청구항

1. A CO2 recovery method comprising: a CO2 absorption process of bringing a gas to be treated into contact with a CO2 absorption liquid, thereby causing CO2 contained in the gas to be treated to be absorbed by the CO2 absorption liquid; anda CO2 absorption liquid regeneration process of heating the CO2 absorption liquid, which has absorbed CO2, in a CO2 absorption liquid regeneration tower, to release CO2 from the CO2 absorption liquid to regenerate the CO2 absorption liquid,wherein the CO2 absorption liquid regeneration process includes measuring a liquid surface level of the CO2 absorption liquid in a second storage part which is to be supplied from the CO2 absorption liquid regeneration tower to the CO2 absorption tower, and controlling the liquid surface level of the CO2 absorption liquid between a first storage part and the second storage part on the basis of the measured liquid surface level.
