摘要： An absorbing solution according to the present invention is an absorbing solution that absorbs CO2 or H2S in gas or both of CO2 and H2S. The absorbing solution is formed by adding desirably 1 to 20 weight percent of tertiary monoamine to a secondary-amine composite absorbent such as a mixture of secondary monoamine and secondary diamine. Consequently, it is possible to control degradation in absorbing solution amine due to oxygen or the like in gas. As a result, it is possible to realize a reduction in an absorption loss, prevention of malfunction, and a reduction in cost. This absorbing solution is suitably used in an apparatus for removing CO2 or H2S or both of CO2 and H2S.

摘要： A method and system for desulfurizing flue gas in which desulfurization is effected by bringing absorbent slurry containing limestone into contact with flue gas. The method classifies absorbent slurry extracted from a desulfurization absorber, returns a fine-side fluid to the desulfurization absorber, and sends a coarse-side fluid to a solid-liquid separator. Supplied limestone powder is mixed to yield limestone slurry by a solid-liquid mixer, and the limestone slurry is classified, sending the small-particle fluid component thereof to the desulfurization absorber, and sending the large-particle fluid component thereof to a limestone fine grinder. And, limestone contained in the large-particle fluid component is finely ground by the limestone fine grinder and the finely ground limestone is sent to the desulfurization absorber. According to the desulfurization method and system, the concentration of limestone in the desulfurization absorber is increased while the concentration of residual limestone in by-product gypsum is kept low, whereby the desulfurization performance of the absorber can be enhanced, and the operation power for the whole system can be decreased.

The inlet side absorption tower is constructed in the form of a parallel-flow absorption tower wherein the flue gas flows downward for favorable collection of dust and absorption of sulfur dioxide. The outlet side absorption tower is constructed in the form of a counter-flow adsorption tower wherein the flue gas flows upward for favorable absorption of sulfur dioxide. The absorbing fluid within a tank is injected upward from a plurality of spray pipes.

Interval P1 of collecting plates 121 of the liquid drop eliminator 120 is made larger than interval P2 of collecting plates 119 of the mist eliminator 118. Thereby, liquid drops having larger particle diameter contained in the exhaust gas are collected by the liquid drop eliminator 120.
