Experimental Study on Treatment of Modified Lye with Hydrogen Sulfide in Coal Mines
摘要
Abstract
To improve the absorption efficiency of lye treated with hydrogen sulfide in coal mines, a kind of single sodium carbon-ate lye was taken as the basic raw material to modify the absorption lye by adding the surfactant SDBS and the oxidant hydrogen peroxide, and the effects of reagent addition on the hydrogen sulfide removal efficiency were discussed. Experiments show that the concentration of sodium carbonate is directly related to the removal rate of hydrogen sulfide. When the concentration of sodium carbonate solution is increased to 2%, the initial removal rate of hydrogen sulfide is 100%; but after the oscillation, the problem of secondary hydrogen sulfide emission is more significant; with the increase of SDBS concentration, the removal rate of hydrogen sulfide from lye gradually increases, and the effect of hydrogen peroxide on the absorption of hydrogen sulfide from sodium carbon-ate solution is obviously improved. Finally, this experiment is proposed based on the actual situation. The optimum ratio of modi-fied lye by hydrogen sulfide treatment is: sodium carbonate solution concentration of 2%, surfactant concentration of 0.4%, oxidant concentration of 0.6%.关键词
