Problems with steam and circulating water in the jacket
Thread Content
Jacketed reactors use steam and circulating water to control temperature. When the steam pressure in the jacket is 1 bar, the temperature becomes too high and cooling is necessary. Can circulating water be introduced directly without replacing the steam?
Circulating water is generally not chosen; when the temperature is high, scaling tends to occur inside the jacket, so it’s best to use softened water
It doesn’t seem like that’s the right way to do it; otherwise, the equipment might get damaged
Don’t worry about what kind of water to use; it’s about passing high-temperature steam into cold water. .
It is recommended to control the amount of steam first, rather than using water directly for control
1 Bar of pressure is already considered high; the absolute pressure is only around 100 degrees, right? The gauge pressure would be a little over 100 as well? ! Just use hot water directly, isn’t that it? !
The temperature during the reaction phase in a reactor varies
It can be used in emergency situations when conditions are harsh; under normal circumstances this approach should not be used, as water and steam will interact inside the jacket, causing damage to the glass-lined surface. When designing general process equipment, a reflux device is usually included in the heating system; this reflux device serves to maintain a certain temperature balance. Therefore, even if the temperature rises, as long as it hasn’t reached a level that is absolutely unacceptable. The steam should be vented first, and then water should be introduced to cool it down.
What is a heating device with reflux? Could someone explain it in detail? Thank you very much
I have used such kettles; when used with circulating water, it’s difficult to control the temperature； Optimization should involve mixing the circulating water and steam inside the drum before they enter the jacket of the reaction vessel
In that case, at different reaction stages – with the reaction temperature at 90 degrees in the initial stage and dropping to 60 degrees in the middle stage – isn’t it difficult to make adjustments? Use circulating water to lower the drum temperature?
