Study on Experimental Device of Removing TRS Gas with ClO₂

Abstract:

In order to remove the malodorous pollutants of total reduced sulfur (TRS) produced by kraft pulp mill, the experimental device was designed to remove the TRS gases in accordance with the principle of ClO₂ oxidizing TRS gases. After ClO₂ oxidizes TRS gases, the substances produced are absorbed by lye, which achieve the purpose of removing TRS gases. At the same time, these alkali absorber can be reused to the sulfur cycle of kraft pulp mills. With the self-designed experiment apparatus, the removal rate of H₂S and CH₃SH are 99.40% and 99.8% respectively, the concentration of H₂S reduces from 1.275g/m³ to 0.137mg/m³, the concentration of CH₃SH reduces from 1.457g/m³ to 0.032 mg/m³, which both reach national grade iii emission standards.
