New Wet FGD Process Using Granular Limestone | Industrial & …

 · A new wet limestone−gypsum process for flue gas desulfurization (FGD) has been developed. The main difference compared to a conventional wet FGD process is the ability of the new process to utilize granular limestone directly as a desulfurizing reagent. Thus, the pulverizing of limestone, which causes power consumption, can be avoided. The performance of the wet FGD process …

Determination of Flue Gas Desulfurization by Analyzing Limestone …

In order to eliminate the SO 2, the flue exhaust gases from a coal-fired power plant are usually passed through a spray of limestone slurry in the scrubber. The resultant reaction typically traps over 90% of the SO 2. Nearly 80%–85% of the global FGD units set up in power plants use wet limestone scrubbing compared to other technologies.
