摘要

以油酸甲酯和油酸乙酯混合液(体积比为1∶1)为吸收剂,研究了吸收剂温度、填料层高度、吸收剂的循环使用对乙酸丁酯废气的吸收效果。结果表明,当填料层高度1 000 mm,吸收剂温度10℃时,乙酸丁酯吸收率可达94.4%,在解吸后的吸收剂重复使用其吸收率稳定在91.3%;双塔吸收中,当吸收剂流量3.7 L/h,进塔气体流量2 m~3/h,吸收剂温度10℃时,乙酸丁酯最终出塔浓度均小于80 mg/m~3,达到天津市排放标准。
        The butyl acetate waste gas was absorbed by the mixed solution of methyl oleate and ethyl oleate.The effects of absorbent temperature,filler layer height,and number of cycles of absorbent on the absorption of butyl acetate were studied.The results showed that when the height of the filler layer was 1 000 mm and the absorbent temperature was 10 ℃,the absorption rate of butyl acetate can reach 94.4%.Absorption of the absorbents reduced the absorption rate rapidly,and the absorption rate was stable at 91.3% after desorption.In the double tower absorption,when the absorbent flow rate was 3.7 L/h,the gas flow rate into the tower was 2 m~3/h,and the absorbent temperature was 10 ℃,the final concentration of butyl acetate was less than 80 mg/m~3,which reached the emission standards for other industries in Tianjin VOCs.
