Temperature control for isothermal reactions
Thread Content
Our reaction is carried out under isothermal conditions, with the temperature needs to be maintained within a narrow range – approximately a 10°C range. Circulating water is used to control the temperature; I’m not sure whether it’s necessary to keep the temperature at its upper limit given the cold weather at present Personally, I think as long as our system can remain stable, there’s no need to change the temperature setting based on the weather! All that needs to be changed is the amount of water circulating! I hope experts can provide a detailed explanation!
“The temperature range of about 10°C is quite wide; why is it necessary to keep the temperature at its upper limit when it’s cold? Is it possible that the temperature measurement point is not representative?
The measurements are very accurate. When it’s cold, it’s necessary to set the temperature higher, according to the deputy manager of the workshop. I don’t really understand why this is necessary either
I think what your leader said makes sense. It is necessary to consider whether the temperature measurement points chosen are representative. It should be understood that the temperature at each point within the reactor is different. In winter, there is a large temperature difference between the inside of the reactor and the outside environment; where there is a temperature difference, heat transfer occurs, and where there is heat transfer, a temperature difference persists.
It’s not necessary; as long as the temperature control point is in the right position and the flow rate of water in the circulation system is well regulated, the temperature will remain within an appropriate range, and there won’t be large fluctuations in the water volume, which can be controlled
I can’t help you much either; come and learn *it!
I’m here to learn* too. I hope those who know can tell me
In a steady-state reaction, as long as there are no significant fluctuations in the temperature of the circulating water, controlling the flow rate will ensure that the reaction temperature remains under control. When the temperature is low, the corresponding heat loss is greater; it is therefore reasonable to maintain a higher reaction temperature.
Control the temperature according to the principles; as long as the analysis results are normal, that’s sufficient. Safety should also be ensured, and there is no need to control it to the upper limit.
Fully consider the impact of temperature differences! !
