Abstract

The Chiyoda Thoroughbred 121 (CT-121) flue gas desulphurisation (FGD) plant is one of the most competitive wet scrubbing technologies currently on the market. The principles of the CT-121 FGD process and the unique Jet Bubbling Reactor (JBR) are discussed in this paper and comparisons are made to the more conventional wet limestone based FGD processes.

The CT-121 FGD process is the result of reversing the conventional concept for wet limestone based FGD. In the CT-121 design, the absorbent liquid is the continuous phase, and the flue gas is the dispersed phase. This is accomplished in the patented JBR, in which the flue gas is forced through the absorbent liquid.

The license for design and construction of CT-121 FGD Plants in Europe has been awarded to BWE A/S together with its parent company STF s.p.a. of Italy.
