In place of sulfuric ,acid,, when soda ,ash, is added, sodium sulfate is formed. Na 2 SO 4, which is water-soluble brought back in the absorber tower for further use. As seen from the above equations, chemical reactions are highly pH dependent. Correct pH conditions are necessary to increase the reaction rate for higher scrubber efficiency.

Flue Gas Desulfurization | EKATO

The picture provides a simplified flowchart of such a plant, in this case the two-stage KRC flue gas ,desulfurization, process. With this process, the sulfur dioxide (SO2) contained in the flue gas is absorbed chemically in an aqueous washing suspension of limestone (CaCO3), quicklime (CaO), or slaked lime (Ca(OH)2) according to the simplified formula

The Global Rise of Zero Liquid Discharge for Wastewater ...

Zero liquid discharge (ZLD)—a ,wastewater, management strategy that eliminates liquid waste and maximizes water usage efficiency — has attracted renewed interest worldwide in recent years. Although implementation of ZLD reduces water pollution and augments water supply, the technology is constrained by high cost and intensive energy consumption.
