The ,desulfurization, processes of interest in this program are the lime, limestone, and double alkali wet scrubbing of flue gases produced in the combustion of coal in steam power plants. More specifically, problems associated with FGD waste disposal are being defined, and assessments are being made of the operational feasibility, performance, and costs of current disposal methods.

In most cases, activated carbons were used for the adsorption of compounds with weaker polarity from gas-phase or polar fluid-phase such as the adsorption of organics in ,wastewater,. Thus, one of the main challenges for adsorptive ,desulfurization, of liquid hydrocarbon fuels is to selectively separate the sulfur compounds of low polarity from a non-polar fluid phase [9] .

Using acids as HBDS, the ,desulfurization, efficiencies of some DES HBDs were as follows: p-toluenesulfonic acid (PTSA) > 5-sulfosalicylic acid > 4-aminosalicylic acid. A positive correlation was observed between DESs ,acidity, and ,desulfurization, efficiencies; i.e., DES with stronger ,acidity, exhibits higher ,desulfurization, capabilities .

21/3/2016, · Sulfur, whose content in coal can be as high as 5%, is released as sulfur dioxide in the firing process. Capturing sulfur dioxide by passing the flue gas through an aqueous limestone slurry results in gypsum (calcium sulfate). Adding ,formic acid, to the ,desulfurization, cycle increases the efficiency of sulfur separation. 10.6.3 Well Acidifiers
