摘要
采用新型高效立体传质塔板(CTST),对济南石化分公司的含硫污水汽提塔进行技术改造,在原塔外壳、降液管以及上部填料段等均不变的条件下,仅用CTST塔板替换原浮阀塔板,改造后处理能力由原来的100t/h提高到180t/h,净化水氨氮含量降低到50mg/L以下,实现了净化水的全部回用。
This paper introduces the operational performances of the combined trapezoid spray tray(CTST).In the technical reconstruction of the sour water stripping column for oil refineries,this tray was used instead of F1 float tray in the same column shell.After the technical reconstruction, the treating capacity was increased by more than 80%, and the ammonia content of the purified water at the column bottom was lower than 50 mg/L.
