2007 · Chemical Engineering · Instrumentation and Process Control · Process Measurements and Instrumentation
Chemical Engineering (CH) 2007

An operator was told to control the temperature of a reactor at 60 °C. The operator set the set-point of the temperature controller at 60. The scale actually indicated 0 to 100% of a temperature range of 0 to 200 °C. This caused a runaway reaction by over-pressurizing the vessel, which resulted in injury to the operator. The actual set-point temperature was
