摘　　要：介绍了大通量新型高效塔板——立体传质塔板(CTST)的特性,采用该塔板改造常压蒸馏装置的常压塔。在保持原塔外壳不变,仅采用CTST塔板替换原塔盘,改造后,操作弹性大,生产能力可提高50%～100%,最大加工量可达到1600kt/a,最低加工量为720kt/a。The performance characteristics of a new type of high-flux high-efficiency tray-CTST were introduced,which was adopted to improve the atmospheric pressure tower of the atmospheric distillation unit.Maintaining the original tower shell unchanged,but only used the CTST tray to replace the original tray.After modification,operation flexibility was larger,production capacity could be increased by 50% ~ 100%,the biggest processing capacity could reach 1,600 kt/a,the minimum processing capacity was 720 kt/a.
