Comparison of conventional Fuel Gas Desulfurization (FGD) with BaS

Fuel Gas Desulfurization (FGD) is a widely adopted technology used to remove sulfur dioxide (SO2) from a variety of gas streams, including those produced by coal-fired power plants, oil refining, cement manufacturing, and other industrial processes. The conventional method of FGD involves the use of scrubbers to wash the flue gas with a slurry of lime or limestone, which reacts with the SO2 to produce calcium sulfate (gypsum).

However, FGD has some inherent limitations. For instance, the scrubber is susceptible to corrosion due to the acidic nature of the slurry, and the gypsum residue produced from FGD needs to be disposed of as solid waste, resulting in additional costs.

BaS, on the other hand, has emerged as a viable alternative to conventional FGD. In the BaS process, the flue gas is passed through a slurry of BaS, which reacts with the SO2 to form BaSO4, a solid precipitate that can be subsequently removed by filtration.

Unlike conventional FGD, the BaS process does not produce any hazardous waste, and BaS is a more effective desulfurizing agent than limestone or lime.

Use of BaS in sulfur removal

BaS is a popular choice for sulfur removal in the pharmaceutical industry due to its unique chemical properties. The compound reacts readily with sulfur compounds to produce barium sulfate, which is poorly soluble in water and can be easily filtered.

The use of BaS as a sulfur removal agent is particularly relevant in the production of pharmaceuticals, as many drugs contain sulfur compounds that are toxic to humans. BaS has also been used effectively in the removal of sulfur from crude oil and natural gas.

The use of BaS for sulfur removal is not without its drawbacks, however. The reaction between BaS and sulfur compounds produces hydrogen sulfide gas, which is toxic, flammable, and has an unpleasant odor.

Proper ventilation and safety measures should be in place when working with BaS to ensure the safety of workers. Uses of BaS in ceramics, flame retardants, and luminous paints
