The utility industry today finds itself confronted with two opposing crises: A cleaner environment versus increased energy requirement. Federal and local governments are pressuring industry to substantially reduce its stack emission to the environment. The concentration of the gaseous pollutants also influences local climatic conditions and lead to global warming. Flue gases emitted due to combustions of heavy oils and coal, boiler and power plants contain toxic gaseous pollutants like Oxides of sulfur (Sox), Oxides of Nitrogen (No_x), carbon monoxide (CO), Hydrogen Sulfide (H₂S) etc., A treatment before being discharged into the atmosphere is vital for safe environment. ATurbulent Bed Contactor (TBC) is an excellent air pollution control device, which is used as wet scrubber for the simultaneous removal of pollutant gases. TBC possess significant advantages such as the ability to operate at large gas and liquid throughputs without plugging and the possibility of obtaining high heat and mass transfer rates. Because of its tremendous turbulence and mixing characteristics self-cleaning is possible without much scale formation and it offers high scrubbing efficiency. The process consists of a scrubber, a hold tank and a liquid solid separator. The process involve sodium based absorption of sulfur dioxide followed by reaction outside the scrubber with lime and /or limestone to produce a solid calcium sulfite /sulfate waste in excess and regenerated sodium scrubber feed solutions. Pollutants gases removal in excess of 95% can be easily achieved and lime utilization higher than 95% attained. The system operating conditions can be controlled to produce a solid waste containing low levels of dissolved solids and good handling characteristics.
