Application of DeltaV Control System in DCS Reconstruction
of Solvent Deasphalting Unit
Chen Long
[Abstract]The original instrument of the solvent deasphalting device is controlled by a secondary panel-mounted instrument. The instrument integrity rate, automatic control rate, and stability rate are only 97%, 90%, and 95%. It is updated to the DeltaV Chinese control system through DCS transformation. The instrument integrity rate is only 97%, 90%, and 95%. The self-control rate and stability rate were increased to 99.5%, 99.7%, and 97.2% respectively.

溶剂脱沥青装置自1990年4月投产以来,其仪表一直使用二次盘装仪表控制,多数盘装仪表已经使用20余年,原产品厂家已停产,备品备件已不支持,加上装置原配置还有部分机械式仪表和气动基地式仪表,装置日常维护十分困难,无法满足安全长周期运行的需要。(剩余4693字)
