Maintain temperature during the reaction process
Thread Content
Dear experts, I have a question: when carrying out reactions in a jacketed reactor and it is necessary to maintain a constant temperature during the reaction, is it required to use the jacket for heat exchange?
By \"thermal insulation,\" it is meant to maintain the temperature within a certain range; this temperature may vary over different periods of time. Therefore, the heat exchange medium inside the jacket is needed to adjust it to the desired temperature.
If the temperature retention remains constant, is jacketed heat exchange still necessary during this process?
Question to the original poster: Is the reaction enthalpy zero for this reaction process?
This reaction is exothermic; heating is carried out first, followed by heat retention. I know that a jacket is needed for heat exchange during heating, but I’m not sure if it’s necessary for heat retention as well
Do you plan to remove and reinstall the insulation frequently?
If it’s high, it goes down; if it’s low, it goes up. This is to maintain a constant temperature during the process.
Thermal insulation is a dynamic process that requires PID control: the temperature should be reduced when it exceeds the set value, and increased when it falls below that value. Of course, there is definitely a tolerance associated with the set values. Otherwise, a steady state cannot be maintained. It is relatively difficult to control the temperature of enamel tubes. Temperature control for stainless steel is simpler.
