MEASUREMENT DEVICE, MEASUREMENT METHOD, AND CARBON DIOXIDE RECOVERY SYSTEM

摘要

Disclosed is a measurement device with which it is possible to quickly measure the carbon dioxide content of an absorbent solution circulating through a carbon dioxide recovery system. The measurement device comprises: a gasification unit (2), wherein an organic solution in which an inorganic gas has been dissolved is gasified and then discharged together with a carrier gas; an organic gas retention unit (3), wherein the gas discharged from the gasification unit (2) is fed and the inorganic gas is allowed to pass through while the organic gas is retained at a first temperature and the retained organic gas is discharged at a second temperature that is higher than the first temperature; an inorganic gas separation unit (5), wherein the inorganic component contained in the inorganic gas that has passed through the organic gas retention unit (3) is separated and discharged; an organic gas separation unit (6), wherein the organic component contained in the organic gas discharged from the organic gas retention unit (3) is separated and discharged; and a detection unit (7), wherein the inorganic component discharged from the inorganic gas separation unit (5) and the organic component discharged from the organic gas separation unit (6) are detected.
