Simultaneous ash and sulfur removal from bitumen ...

 · Effect of leaching with sulfuric acid followed by flotation on ash and sulfur removal. For optimal conditions, 43% of the ash and 52.9% of the pyrite sulfur (36.45% of total sulfur) were removed from bitumen. The leaching process was applied to the float samples using sulfuric acid. This process improved the ash and sulfur removal percentages.

CASE STUDY SO2 Removal From Power-Plant Stack Gase ...

During coal combustion the sulfur in the coal reacts to form SO2 and very small amounts of SO3. Eighty-five percent of the ash in the coal leaves the boiler in the stack gas as fly ash; nitrogen emerges as N2, and the carbon, hydrogen, and sulfur in the fuel are oxidized completely to CO2, H20, and SO2. Table CS 2.1 Coal Properties 1.

Coal Cleaning With Scrubbing For Sulfur Control An Engineering

In the past its principal purpose was to reduce the ash-forming impurities. However, today cleaning is of significant value in reducing the sulfur content of certain coals. Its applicability in this regard is not universal due to the various forms that sulfur occurs in coal. Sulfur exists in coal in two principal forms; organic and inor- ganic.
