On the design of the jacket bypass pipes for hydrolysis reactors

Thread Content

The company has newly installed a 50 m³ hydrolysis reactor with a temperature of 200° and a pressure of 1.0 MPa; it operates in batch mode with a production cycle time of 6.5 hours, and external steam is used for heating and cooling. The original design was a traditional external jacket design! Currently, a design using external coils around the tank wall for heating and cooling is being considered: Advantage: The coils reinforce the tank wall, allowing it to be made thinner, which facilitates heating and cooling. Reduce operating costs. My opinion is: warming up is no problem; the key is cooling down. At 160°, cold water must be added to cool down the system; this can lead to vapor lock. The reaction taking place inside the reactor is exothermic, and the temperature cannot be reduced quickly, posing a risk of explosion! ! Now, three connected tubes are used as companion tubes, and the heat exchange area remains the same as that of the original jacket! Please, any experts or those who have used this type of reactor could offer some advice! ! !
