Spray jet liquid distributors used to be adopted in the vacuum tower of the second distillation unit of Refinery of Yanshan Company for the second mid-pumparound return to the tower and scrubbing oil inlet into the tower. Plugged spray jets caused abnormal operation. Second mid-pumparound recycle was too small and the second mid-pumparound oil was entrained into the third vacuum side stream. Viscosity and colourity of the product have been influenced by the bad scrubbing effect. Now, the Spray jet distributor has been replaced by a gravity trough-type distributor developed by Tianjing University. The above mentioned problems in production have been overcome and the product quality has been guaranteed.

中国石化股份公司燕山分公司炼油厂二套蒸馏装置减压塔的二中返塔和洗涤油进塔原采用喷头式液体分布器,因喷头堵塞导致操作异常,减二中循环量过低,减二中油被夹带至减三线,洗涤效果不佳,产品的粘度、比色受到影响。用天津大学的重力型槽式分布器替代喷头后,减二中和洗涤段操作正常,产品质量有了保证。

This paper describes the revamping design for the expansion of the second distillation unit at DLPEC. New technology and new equipment such as high efficiency column tray are used. After revamping, the annual capacity of the unit is increased to 5. IMt, the quality of the main products produced from the atmospheric and vacuum units is up to the design requirement, and its energy consumption accounts for 386. 94 - 406. 60MJ/t, lower than design value.

通过对中国石油大连石化分公司Ⅱ套蒸馏装置扩能改造的设计实践,总结归纳了在老工艺装置上采用立体传质塔盘等新技术、新设备的应用成果。改造后的标定数据表明,改造后装置处理能力可达5.1Mt/a,常、减压系统主要产品质量满足设计要求,装置能耗在386.94~406.60MJ/t,低于设计值。
