TL;DR: In this article, the authors proposed a process that uses sulfur dioxide from coal combustion as a raw material to synthesize polymeric ferric sulfate (PFS), a water treatment agent.
Abstract: We propose a process that uses sulfur dioxide from coal combustion as a raw material to synthesize polymeric ferric sulfate (PFS), a water treatment agent. The process uses sodium chlorate as an oxidant and ferrous sulfate as an absorbent. The major chemical mechanisms in this reaction system include oxidation, hydrolysis, and polymerization. Oxidation determines sulfur conversion efficiency while hydrolysis and polymerization control the quality of product. Many factors, including SO{sub 2} inlet concentration, flow rate of simulated flue gas, reaction temperature, addition rate of oxidant and stirring rate, may affect the efficiencies of SO{sub 2} removal. Currently, the effects of SO{sub 2} inlet concentration, the flow rate of simulated flue gas and addition rate of flue gas on removal efficiencies of SO{sub 2}, are being investigated. Experiments shown in this report have demonstrated that the conversion efficiencies of sulfur dioxide with ferrous sulfate as an absorbent are in the range of 60-80% under the adopted process conditions. However, the conversion efficiency of sulfur dioxide may be improved by optimizing reaction conditions to be investigated. Partial quality indices of the synthesized products, including Fe{sup 2+} concentration and total iron concentration, have been evaluated.

TL;DR: In this article, the authors proposed a solution generator consisting of a retort, an acid liquor metering pump, a sodium chlorate solution metering pumps, a heating water jacket, a safety valve, a water ejector, and a control panel.
Abstract: The invention belongs to the technical field of chemical equipment, and in particular relates to a chlorine dioxide solution generator taking sodium chlorate as a reaction raw material. The chlorine dioxide solution generator comprises a retort, an acid liquor metering pump, a sodium chlorate solution metering pump, a heating water jacket, a safety valve, a water ejector, and a control panel, wherein an acid liquor distributor and a sodium chlorate solution distributor are arranged on the lower part in the retort in turn; the lower end of the retort is provided with a retort exhaust valve; the upper part and the lateral surface of the retort are provided with a chlorine dioxide gas outlet and a chlorine dioxide solution outlet respectively; and the heating water jacket is also provided with a heating water jacket feed liquor and discharge air valve, an air communication valve, a heating water level display, a heating water temperature monitoring controller, and the like. The chlorine dioxide solution generator has the advantages of compact and small structure, simple operation, safe and reliable running, and convenient maintenance and use.

TL;DR: In this article, a salt solution, particularly aqueous sodium chlorate, is acidified electrolytically at a higher current efficiency than has previously been the case by employing a plurality of multiple compartment cells, in which the effluent from intermediate compartments is passed through more anodic compartments.
