Preparation of New Surfactant and Study on its Application in Ultra-low Emission of Flue Gas

Abstract

In this paper, with different types of optimal surfactant monomers and potentiators mixed, the optimum formula of the new surfactant was obtained. The new surfactant with low toxicity, low cost and good dust removal effect was developed by the simulated flue gas experiment and verified the removal efficiency of the new surfactant on the particulate matter in the flue gas. It provided a reference for the industrial application in ultra-low emission of coal smoke. The results showed that the new surfactant could effectively reduce particulate matter in the simulated flue gas, and be the best to the dust particle size less than or equal to 1 micron. The optimum formula was worked out to be: anionic surfactant sodium dodecylbenzene-sulfonate (SDBS) 0.06%, anionic surfactant rapid penetrant T 0.06% and inorganic salt NaCl 1%.
