Solvent Deasphalting Unit Distributed Control System

With the continuous development and advancement of the computer control technique , the application of the Distributed Control System has become much broad. With the mature and development of the Network technology and Windows operation system , the Distributed Control System has being developed to the much flexible and understandbility opened Windows NT operation system and Control management Network from the tradition UNIX operation system and process control network. The Distributed Control system TPS of the American Honeywell company is a practical example.The Oil Refinery Plant of JiLin chemical Industry Company have advanced Distributed control system. For the example, TDC-3000 Serial production of the Honeywell Company , CENTUM-XL and CENTUM-CS system of the YOKOGAWA. In the course of the extension construction. Solvent de-bitumen plant of the Oil Refinery introduced the advanced TPS.(Total plant system) Distributed Control System of the Honeywell company in 2000. By the Application and normal operation of TPS (Total Plant System), The TPS's advantage of Windows operation and Control management network has been brought into play fully.According to the practical Application example of the TPS distributed control System in the Solvent de-bitumen plant, this paper has discussed the application characteristic of the TPS Windows NT operation system and design and realize of its control management network system. By the practice , it is indicated that opened Windows NT operation System and control management network system have deep-drawn meaning and broad foreground as the solid characteristic and sufficiency application unit of the DCS in industry control process.
