Improvement of Gas Cleaning Processes for Thermal Power Plants from Sulfur Dioxide using Electro Dialysis Technology
Abstract: Material flows during solid fuel combustion in power units are considered. It is shown that an alternative variant of the flue gas desulphurization process can be used as a reagent – an absorber of sulfur dioxide sodium sulfite. The resulting reaction product, sodium bisulfite, is reduced to sulfite in an electro dialysis apparatus to obtain a demanded product – sulfur dioxide. The recovery process of the depleted absorber has been studied on a pilot electro dialysis unit. Experimental dependences of the current density on the voltage level supplied to the electro dialysis cell at different temperatures of the solution are obtained. It is shown that an additional increase in electricity consumption for the recovery of the reagent-absorber is 4.5 % of the power unit capacity with a sulfur content of 2 % in the fuel.
Keywords: electro dialysis, current density, sodium sulfite, sulfur dioxide, limestone technology.
