Abstract

Real-time, on-line measurement of key physical parameters as well as their variations is the most crucial problem for safety running of reciprocating compressors in petrochemical plants. In this paper, a method for condition monitoring and fault diagnosis of reciprocating compressor based on FBG sensors is proposed. A fiber optic accelerometer is demonstrated, which is used for detecting the vibration of crankcase, crosshead and cylinder of the compressor. FBGbased temperature sensors are used to monitor the variation of the suction/vent valve temperature. A monitoring system included hardware and software for the reciprocating compressors is developed and applied in a petrochemical plant.
