Effect of the Main Operating Variables on Efficiency of Treating Industrial Flue Gases Using Potash and Yellow Phosphorus

Abstract

One of the main environmental threats is the gases  from  industrial process or other emissions activities, albeit they are several, all concern directed toward Nitrogen oxides NOX and Sulfur oxides SOX; because they may be a hazard for human and environment. The separation of nitrogen and sulfur oxides from waste gases is found to be affected by several operating parameters, this paper discusses some of them. The experiments were done on a bench-scale; 2900 ppm  and 550 ppm  , and using, (10) g , (0.5) g yellow phosphorus () at , with vigorous stirring for removal. The removal efficiency is monitored for different values of the emulsion temperature, yellow phosphorus () weight, and the emulsion stirring intensity. The removal efficiency isproportional to the emulsion’s temperature in the range ( 45 OC to 65 OC).The optimum temperature was, Nevertheless, the results revealed the removal efficiency is proportional to the phosphorus weight, that the efficiency of removal increases as the P4 content increases. Increasing stirring intensity will directly increase the removal percentage and the optimum stirring intensity is 1734 rpm.
