Abstract
Official abstract text for this publication.
There is provided an exhaust gas treatment system including a CO 2 recovery unit with further enhanced energy efficiency. The exhaust gas treatment system ( 1 ) includes: a CO 2 recovery unit ( 10 ) including a CO 2 absorption column ( 11 ), an absorbing solution regeneration column ( 16 ), a condensate supply pipeline ( 15 ) for supplying condensate, which contains CO 2 absorbing solution discharged from the CO 2 absorption column ( 11 ) to a bottom portion of the absorbing solution regeneration column ( 16 ), and a CO 2 separation section ( 22 ) for performing heat exchange, via a heat exchanger ( 23 ), between the CO 2 discharged from the absorbing solution regeneration column ( 16 ) and the condensate; and an exhaust gas heat exchanger ( 5 ) provided on a gas upstream side of the CO 2 recovery unit ( 10 ) for performing heat exchange between exhaust gas before flowing into the CO 2 recovery unit ( 10 ) and the condensate.
First claim
Opening claim text (preview).
The invention claimed is: 1. An exhaust gas treatment system provided on a downstream side of a boiler which combusts fuel to heat water and generate water vapor, comprising: a CO 2 recovery unit including: a CO 2 absorption column for bringing gas containing CO 2 generated in the boiler into contact with a CO 2 absorbing solution so that the CO 2 absorbing solution absorbs the CO 2 and thereby the CO 2 is removed out of the gas; an absorbing solution regeneration column…
