Desulfuriation. A SO 2 scrubber system is the informal name for flue gas desulfuriation FGD technology which removes or scrubs SO 2 emissions from the exhaust of coal-fired power plants. A scrubber works by spraying a wet slurry of limestone into a large chamber where the calcium in the limestone reacts with the SO 2 in the flue gas. There are some variations in design of scrubbers

2020-5-26Sulfur dioxide SO2 is a colorless gas or liquid with a strong choking odor. It is produced from the burning of fossil fuels coal and oil and the smelting of mineral ores aluminum copper inc lead and iron that contain sulfur. Sulfur dioxide dissolves easily in water to form sulfuric acid. Sulfuric acid is a major component of acid rain

2019-5-26This paper provides preliminary results on the novel study of ammonia scrubbing for the removal of carbon dioxide from flue gas. Experimental results indicated the potential of CO2 reduction by NH3 scrubbing is very promising. The overall CO2 removal efficiencies could be above 95 under proper operation conditions. The absorption capacity of NH3 was around 0.9 kg of CO2kg of NH3 reagent

ABSTRACT The report gives results of a laboratory study of the control of SO2 emis- sions from copper smelters by H2S production from copper concentrates. Digestion of neutral roasted pyritic copper concentrates with HC1 was studied as a means of producing sufficient H2S for reaction with the SO2 from converter gas to produce elemental sulfur
