摘　　要：将复合床层技术和新型规整填料Chaopak用于常减压蒸馏装置减压塔的扩能改造。通过对二级减压塔的操作条件和产品质量的分析表明 ,各侧线产品质量和收率均达到设计要求。全塔压力降为 93 3 .3Pa ,远低于15 99.9Pa的设计值 ;在保证生产能力提高的同时 ,产品的收率和原油利用率也得到了提高 ;该塔还具有较大的操作弹性。该技术在常减压蒸馏装置的扩能改造中具有很好的应用前景。The complex bed technology and new structured packing Chaopak have been used in the expansion revamping of vacuum column of atmospheric and vacuum distillation unit. The analysis of two-grade vacuum column operation conditions and the product quality shows that the products of side streams and the yield have reached the design requirements. Total column pressure drop is 933.3 MPa, which is much lower than the design value (1 599.9 MPa.) Not only has the production capacity been increased, the production yield and crude oil utilization rate have been enhanced as well. In addition, the vacuum column has a good operation flexibility.
