摘要
某厂8 Mt/a常减压装置采用了LPEC公司自主知识产权的减压深拔技术,实践中通过优化操作条件,实现了较低残压(1.6 kPa)和较低全塔压降(1.33 kPa)下,提高减压炉温,实现了总拔收率对应原油实沸点切割温度达到580℃,渣油538℃馏出≤4%(v),且HVGO产品质量合格的设计要求;装置长期满负荷安全运行生产4年7个月,实现了长周期安全生产。
8 MT/a atmospheric and vauum distillation unit of a certain plant adopts the deep-cup distillation of LPEC, and operated to realize deep-cut distillation by increasing the temperature of in the vacuum furnance at lower residual pressure of 1.6 kPa and lower pressure drop of 1.33 kPa. The cut temperature of curde oil TBP is 580 ℃ and the content before 538 ℃ of vacuum residue is less than or equal to 4 %(v), and the HVGO is qualified. The unit is operated for 4 years and 7 months, and long-time safe operation is realized.
