remove sulfur dioxide (SO2) produced in a coal-fired utility boiler, using a limestone sorbent at a calcium/sulfur molar ratio of 2.0-2.5. A unique feature of this technology is humidification of the flue gas in a separate activation reactor, which increases SO2 removal. An electrostatic preci pitator downstream from the poi nt of injection captures the reaction products, along with the fly ...

SULFUR DIOXIDE REMOVAL There are no combustion strategies that can be used to control the generation of sulfur dioxide in PC plants. If sulfur is present in coal it will be converted into sulfur dioxide during combustion. The only recourse is to capture the sulfur, either before the coal is burned using a coal-cleaning process,.

Removal of Organic Sulfur from Coal by .

The processing of high organic sulfur content coals with methanol and ethanol as supercritical solvents has resulted in reduction in sulfur concentrations exceeding 50%. Since the total sulfur removed exceeds the mineral sulfur content of the coal processed, it is evident that organic sulfur is being removed during the reaction. The resulting solid product maintains over 50% of the ...

The optimum sulphur removal time and microwave power for the high sulphur (±3.3 %) coal were difficult to determine. This is possibly due to the uneven distribution of pyrite within the coal structure and thus the samples may be biased. Coal particles of sizes 212 µm and 74 µm showed optimum sulphur removal .

Organic sulfur is found in coal as mercaptans (RSH), disulfides (RS-S-R'), sulfides (R-S-R'), and thiophenes (heterocyclic). Organic sulfur is thus integrated into the carbon structure and difficult to remove. Oxidative ions convert organic sulfur to sulfates which can be dissolved in water or form sulfur dioxide.
