摘要
ＶＧＯ直接溶剂脱油生产石蜡装置投产后八年来针对生产实践中逐步暴露出的薄弱环节进行改造挖潜、消除“瓶颈”制约和优化生产工艺使装置生产水平逐年提高，加工能力由１５０ｋｔ／ａ提高到２２０ｋｔ／ａ，１９９７年硬蜡产量达１１９．
The 8 years developing course of solvent deoiling from VGO for paraffin wax prodution is introduced. After the unit debottlenecking, equipment innovation and optimization of production process, the throughtput of the unit was increased from 150 kt/a to 220 kt/a and the hard wax product reached 119.5 kt in 1997.
