A question about reactor temperature rise
Thread Content
Regardless of whether the sulfur recovery unit is a primary or secondary CLAUS reactor or a tail gas hydrogenation reactor, a common phenomenon is that the maximum temperature rise of the bed (the difference between the highest point temperature of the reactor bed and the reactor inlet temperature) is greater than the temperature rise of the entire reactor (the difference between the reactor inlet and outlet temperatures). Can anyone explain this problem? Is it caused by heat loss from the reactor?
First, the measurement error of the instrument must be eliminated
Is it normal? It is an exothermic reaction, with the value reaching the highest value in the middle of the bed and then gradually decreasing. Exports are definitely the lowest. Because there is no reaction in that part. Therefore, the temperature from the inlet to the outlet must be lower than the temperature to the bed.
