it will se the record of the wave of temperature profile across the reactor. the only way to stop is shut down the charge heater cooling with air and steam in heater chamber, and at the same time cut out the feedstock and depressure the reactor as a sop. I have experience with temperature runway , during first start up of HC it was terrible situation , since many flanges in the reactor were leaks and cough of fire. the peak temperature was around 740 C , and after restart we found channeling in the reactor, and after open the reactor , we found the catayist already agglomerate , and assumed the temperature more than what we saw on the monitor /record.Less
