Carbothermal Reduction of Barium Sulfate-Rich Sludge

01/11/2013  The alkali–barium–calcium (ABC) desalination process is basically an integrated lime/limestone neutralisation process combined with a sulfate removal stage using barium carbonate (BaCO3), and a sludge processing stage. The BaSO4/CaCO3 sludge generated during the desalination stage is treated to recover BaS and CaO by dewatering and thermal processes, with the ultimate goal

Barium Sulphate - Weebly

Barite is processed by carbothermal reduction (heating with coke) to give barium sulfide: BaSO4 + 4 C → BaS + 4 CO In contrast to barium sulfate, barium sulfide is soluble in water and readily converted to the oxide, carbonate, and halides. To produce highly pure barium sulfate, the sulfide or chloride is treated with sulfuric acid or sulfate salts: BaS + H2SO4 → BaSO4 + H2S Barium sulfate ...

Barium sulfate - Wikipedia

Barium sulfate (or sulphate) is the inorganic compound with the chemical formula BaSO4. It is a white crystalline solid that is odorless and insoluble in water. It occurs as the mineral barite, which is the main commercial source of barium and materials prepared from it. The white opaque appearance and its high density are exploited in its main applications.

Study of Thermal Reduction of Barium Sulphate for Barium ...

Reduction of barium sulphate (BaSO 4) to barium sulphide (BaS) is an important step in producing barium chemicals from barite (natural barium sulfate mineral). Barite ore is a basic starting material for manufacturing a variety of barium chemicals such as BaCO 3, Ba(OH)2, Ba(NO 3)2, Ba(HS)2, BaO (Alizahed et al. 2010). Studies on the kinetics of the reduction of barite are very limited. Only ...

Effect of Nature of Coal on Carbothermal Reduction of Barites

coal, the extent of carbothermal reduction of barite increases effectively. Table 3 summarises the effect of quality of coal on carbothermal anaerobic solid phase reduction of barites in the pit furnace. The obtained results show that the general impact of steam coal in the carbothermal reduction of barite increases the yield of barium sulphide.
