Medium-pressure reactor in hydrogen production plant
Thread Content
The technical documentation on hydrogen production units states that if the temperature of the medium-pressure reactor bed suddenly drops to 100–200°C, it indicates an internal leak in the pre-heater ahead of the reactor, as well as a temperature difference across the medium-pressure reactor bed. Could some expert please explain to me what \"cross-temperature\" is, and why a leak in the heat exchanger can cause such a significant drop in the temperature of the reactor?
The medium-temperature reaction is an exothermic reaction; the most likely cause of a significant temperature drop is the leakage of deionized water from the pre-exchanger into the reactor, which leads to a decrease in temperature
Oh, I see. Since it’s an exothermic reaction, it’s impossible for the reactor temperature to drop significantly at the time of feeding! ! !
