摘要
介绍了中国石油天然气股份有限公司大连分公司Ⅱ套润滑油型常减压蒸馏装置加工能力由 2 .8Mt/a扩大到 4.1Mt/a的改造情况及改造后的运行结果 ,并对运行结果进行了分析。改造中采取的措施有 :在初馏塔和常压塔中采用了高效立体传质塔板 ,在减压塔中采用了矩形浮阀塔板 ;对换热流程进行了优化 ;常压炉采用 4路进料 ,减压炉采用 8路进料 ;抽真空系统采用带增压器的三级抽真空系统等。改造后装置各项指标达到设计要求 。
Capacity expansion revamping of the second lube type atmospheric and vacuum distillation unit from 56 000 b/d to 82 000 b/d in Dalian Company and the running effect after revamping are introduced. Running result has been analyzed. Measures adopted for the revamping are as follows: (1) Vertical mass transfer trays with high efficiency have been used in the prefractionator and atmospheric tower, and rectangular valve trays have been used in the vacuum tower; (2) Heat exchanger flow scheme has been optimized; (3) 4-pass feedstock for the atmospheric furnace and 8-pass feedstock for the vacuum furnace; (4) Three-grades vacuum-pumping system with supercharger has been adopted. After revamping, various targets of the unit have reached the requirements of design with low energy consumption.
