Ways to cool a reaction kettle
Thread Content
The reaction vessel needs to be heated and cooled; during heating, the temperature reaches 300°C, and after operation, circulating water is used to cool it down to room temperature. Heated by heat transfer oil; it cannot be mixed with heat transfer oil. During cooling, there is no material inside the reactor, resulting in poor cooling efficiency of the internal coil. Besides heating with heat transfer oil in the external jacket and cooling with internal coils, what other methods are there? Everyone is welcome to discuss!
Is there a mixer? It turns out that by using an internal coil together with a stirrer, the cooling rate is quite fast
Let’s see if this structure is feasible
Internal coils and external jackets are currently the better approaches.
What is the effect of using heat transfer oil to flow through the coils and cooling water to flow through the jacket?
If the reaction is not sensitive to water, it is possible to consider using process water to cool the reactor directly; this water can be reused as well. The reaction is then carried out in an oven
Just circulate the hot heat transfer oil through the heat exchanger to cool it down, and that’s it. Our company has already manufactured several sets of similar equipment for other clients in the past.
Find a way to lower the temperature of the heat transfer oil
A half-pipe jacket could be tried, a dual-channel half-pipe jacket, with water flowing in one channel and oil in the other.
