How to choose a hydrogenation reactor
Thread Content
To select a 3,000-liter open-type hydrogenation reactor, how should its configuration be determined? Pressure of 20 kilograms, temperature of 200 degrees; hydrogenation must take place both above and below the liquid level; low-viscosity fluid; discharge from the upper part; internal coiled tubes. How are factors such as the motor power, type of agitator and its speed, and the distance from the bottom of the tank determined? Is there any expert out there who can give some guidance?
The hydrogenation reactors with a capacity of 3 cubic meters are not very large; their diameter ranges from 1200 mm to 1600 mm at most. The space inside the reactor, where the pressure-bearing heating coils are located, is a bit limited, but it’s still possible to implement such designs. Factors such as motor power, type and speed of the agitator, and its height above the bottom of the reactor are interrelated. First, you need to determine the motor power and speed based on the properties of the medium being stirred – such as viscosity requirements, reaction time requirements, and mixing requirements. After that, you select an appropriate agitator according to the needs of the hydrogenation reaction medium. Once the type of agitator is chosen, the structure of the agitator can be determined, and thus its height above the bottom of the reactor can also be fixed. Therefore, the key factor is to understand the properties and reaction characteristics of the medium throughout the process from feeding it into the reactor to obtaining the final product.
