On January 22, after meticulously organized and struggled to tackle key issues, Yangzi Petrochemical Electric Instrument Center successfully overcome the technical barriers to the operation and successfully completed the system optimization and reformation of the carbon monoxide control system, effectively improving the reliability of the operation monitoring and control of the carbon monoxide compressor unit and ensuring the safety and stability of the carbon monoxide plant Operation has provided a guarantee.
In the original carbon monoxide plant control system, the two compressors each have a control system operating station, equipment manufacturers did not provide a backup system, there is a security risk of system operation, at the same time, the compressor vane valve, return valve and the on-site solenoid valve is also running In order to solve the existing problems, by the end of December, Yangzi Petrochemical Electric Instrument Center used the carbon dioxide heat exchanger to repair the timing, organized the staff to conscientiously compile the maintenance and modification plan, organized the personnel to carry out the research on the compressor control system and the scene Instrument optimization and transformation.According to the requirements of safe operation of the device, they coordinate the equipment manufacturers to complete the operating system screen optimization, hardware redundancy testing, touch screen replacement operation, increase the parameter adjustment function on the touch screen operation, which greatly improves the system's independent maintenance Ability, at the same time, the operating system data backup, to solve the hidden dangers of no standby station, and for the future independent system optimization and transformation laid the foundation.Electrical instrument center personnel also completed the compressor unit 12 valve positioner replacement, Site 38 Taiwan Solenoid valve parts inspection, Solid and replacement tasks, and the implementation of the work field instruments eliminating defects, improving the reliability of the equipment means a carbon monoxide meter.
