1. Introduction. Flue gas desulfurization (FGD) involves the removal of sulphur dioxide (SO 2) contained in gases produced by the combustion of fossil fuels such as coal, oil, municipal solid waste and many industrial processes.SO 2 emissions are a primary contributor to acid rain and have been regulated by every industrialized nation in the world (Córdoba, 2015, …
Limestone is a key raw material in most FGD systems installed to control sulphur dioxide (SO 2) emissions. This report attempts to address the availability of limestone for FGD and also the use of its by-product, FGD gypsum. Limestone is an abundant resource in India with total reserves of 200 billion tonnes.

At present, the main desulfurization process for coal-fired power plant is flue gas desulfurization. The chemical principle of limestone as desulfurizer. During pulverized coal combustion, blending a certain proportion of limestone powder, it can reach the desulfurization effect after a series of chemical reactions. ... Limestone Mill. Kaolin ...
ABSTRACT. Wet flue gas desulfurization (WFGD), using limestone with forced oxidation (LSFO), is a common Flue gas desulfurization (FGD) process where limestone reacts with SO 2 to produce gypsum (CaSO 4.2H 2 O). In South Africa, Eskom's Kusile Power Station utilizes conventional wet ball milling to grind high-grade limestone (96% CaCO 3) to 95% passing 45 …
stone slurry FGD systems. Chemistry for this particu-lar process involve a lime or limestone slurry which consists of a solution of calcium compound solids in suspension as well as calcium salts (sulfites and sul-fates) in solution. These dissolved compounds are generally not a significant problem unless the solution is saturated.
For this, power plants are installing Flue Gas Desulfurization Plant (FGD) or unit. Limestone slurry is sprayed on the incoming flue gas. The sulphur dioxide gets absorbed. The limestone and sulfur dioxide react as follows : CaCO 3 + H 2 O + 2SO 2 ----> Ca +2 + 2HSO 3 - + CO 2.
Reagent Preparation System. The reagent preparation system of flue gas desulfurization (FGD) includes a Wet ball mill and cyclone classifiers which produce a finely ground limestone slurry at 90% solids passing through 325 mesh. One mill slurry tank and one slurry pump is supplied for one wet ball mill. The mill slurry pump will send limestone ...

Most FGD technologies use an alkali sorbent, such as limestone (calcium carbonate), quicklime (calcium oxide), hydrated lime (calcium hydroxide), or sometimes sodium and magnesium carbonate and ammonia, to capture the acidic sulfur compounds from the flue gas.
The standard grind on modern wet FGD systems is 95% passing through a 325 mesh. The components of some existing milling systems can potentially be upgraded to handle the new quantity and grinding requirements. Optimizing the grind of the limestone milling system can have a significant positive impact on limestone utilization.
For a lime FGD system, a lime slaker processing pebble lime is required in place of the limestone wet ball mill. To facilitate the disposal of the solid waste, or to produce a saleable product in the form of high quality gypsum, a forced oxidation system may be utilized to oxidize the main reaction product, calcium sulfite, to gypsum.
