| Abstract: | The ESD system of SORALCHIN Refinery-TS3000 fulfilled the supervisory,control and interlock protection of process parameters and anti-surge control of air compressor.The system is triple-modular redundant(TMR)and fault tolerant.The 2 out of 3 voting system provides FCCU and compressors with proper control and interlock protection.At the same time,about the problems of this system,such as system halt,24V DC power supply and the override of main blow flow low and so on,the improvement suggestion and prevention measurement is presented. |
