摘要
介绍了大通量新型高效塔板——立体传质塔板(CTST)。该塔板与浮阀塔板相比具有的优势为:处理能力提高80％～100％,分离效率高10％～40％,操作弹性高一倍,压降低20％～30％。该塔板在天津联合化学有限公司环氧乙烷EO/乙二醇EC装置扩产改造中已经成功应用,在原塔外壳不变的条件下,仅用CTST塔板替换原浮阀塔板,改造后生产能力提高30％～80％。EO精制塔C302空塔动能因子超过3.OPa^(0.5)。
This paper introduces the structure and operational performances of the combined trapezoid spray tray( CTST) . The CTST has many advantages compared with the float tray, for example, the flux was increased by 80 % - 100% , the separating efficiency was increased by 10% -40% , the range of operation was 2 times and the column pressure drop was decreased by 20 % - 30 % , etc. In the technology transform of the EO/EG units, float trays were replaced by CTST trays. As a result, the output was increased by 30% - 80% . The FT of the ethylene oxide treating column C302 was in excess of 3.0 kg1/2/(s·m1/2) .
