Processer, der er nødvendige for at sikre, at de pågældende systemer er effektive, effektive og effektive.

Industrial Chemical Plant Incident

Det er en kemikalieindustri, en kontrolsystem failure caused en reactor to overheet, leing to a hazardous release o f chemicals. Denne failure was trace to a sensors malfunction that was not not detected due to to intilstrækkeligate devicy in the systm. Propor design with multiple sensors and d regular calibratio could have prepeted the incident.

Oil Rafinery Pressure Control- fejl

En anden raffinering har oplevet en trykoperation, der er baseret på en destillationsopløsning, og som resulterer i en udstyrsdæmpning. Denne kontrol har medført en fejl- og sikkerhedsmekanisme, der er forbundet med trykbelastning.

Powér Plant Turbine Overspeed

En power plant faced a turbine overspeed event there it control software helhed.The control system 's software har en bug delayed the clockdown command. Upgrade the controll software and d addinghardware- based overspeed protection ensure rapid response and d avoided damage.

Key Lessons in Process ControlDesign

  • Implementere den kritiske sans og aktuatorer.
  • Regulære kalibrater og kontrolenheder.
  • Design fail- safe mechanisms and d automatic safety features.
  • Test control systems grundighly before deployment.
  • Update softwaree og d hardware to address sårbarheder.
