Lime and limestone products are used in both wet and dry flue-gas desulfurization FGD processes. In wet FDG processes, these products are slurried with water and sprayed into a flue-gas scrubber vessel. The acidic gases, normally SO 2 and HCl, are absorbed into the water where they chemically react with the lime and limestone. The resulting products, primarily calcium sulfite, can then be oxidized to

lime used to get hydrated lime. Calcium carbonate is used first and foremost in building industry, lime and cement production works, in chemical industry, sugar industry and metallurgy. In agriculture, it is a fertilizer while in power generation industry, it has been used as the cheapest sorbent in boiler flue gas desulphurization processes since
The lime slaker mixes quicklime with water to create calcium hydroxide in a solution which is called lime slurry. Slakers are good for a high volume consumption, or high demand, of calcium. However, when a smaller or medium lime solution is requested, hydrated lime is more efficient because the equipment required to use the hydrated lime is simpler and does not need to be designed to handle an

Jul 30, 2016 The highest desulphurization potential can be achieved by using lime saturated slags. An under-saturation of lime in the ladle slag leads to a decrease in desulphurization for thermodynamic reasons. As opposed to that, a surplus of lime leads to heterogeneous slags, resulting in a decrease of the desulphurization potential for kinetic reasons.
For the production of lime hydrate to be used in flue gas desulfurization plants of power stations or waste incineration facilities, the one-stage hydrator KLE is the optimum solution. In this case, the dust collection filter is not needed because the vapors produced during hydrating are directly conveyed into the flue gas desulfurization plant.
The semi-dry FGD processes employ a circulating fluidized bed, dry spray, or duct dry spray to produce powdered mixtures of calcium compounds. FGD technology using dry processes injects lime or sodium bicarbonate into the furnace of the boiler to absorb the SO 2. The sorbent is then extracted, together with the fly ash, as a mixture of ash and calciumsodium components.
