A process for reducing the sulfur and ash content of coal wherein coal particles are treated in an aqueous slurry with a minor amount of hydrocarbon oil to form coal-oil aggregates. The coal-oil aggregates are separated from ash and mineral matter in the slurry by dissolved gas flotation. Optionally, the coal particles may be treated with a conditioning agent prior to the aggregation …
The oxidation of sulphur dioxide to sulphur trioxide is a reversible process. The pressure is maintained at 1.2-1.5 atm and temperature at 410-430°C. If the temperature rises above 430°C then the equilibrium is displaced away from Sulphur Trioxide, hence it is very important that operating temperature should be maintained in this range.

Grinding fluids containing sulphur or chlorine additives help in reducing the cutting force and improving the surface finish and increasing the life of the grinding wheel. Usually water based emulsions and grinding oils in ample quantity (15-20 litres/min for normal medium sized grinding machine) are used for this purpose.
absorb 90% of the sulphur oxides. Sox emission can be controlled by using low slphur fuel and raw material. Table 2: Process SO 2 Emission The sulfur oxides react with water vapor and other chemicals high in the atmosphere in the presence of sunlight to form sulfuric acids. The acids formed usually dissolve in the
