The features of hydrogenation reactor

By WHGCM September 28th, 2023 90 views
I. Features of WHGCM hydrogenation stirring reactor
A、Using magnetic seal stirring structure: the fully sealed kettle body, the stirring shaft is completely inside the kettle body, with excellent sealing effect. 
B、The motor and other devices are explosion-proof class, which further ensures the safety of the reactor. the basis for choosing the explosion-proof motor of the WHGCM hydrogenation reactor is as follows
    a、 The torque is determined by the larger viscosity of the material (the reaction is dynamic and the viscosity will change), the blade diameter and frontal cross-sectional area of the stirrer, and the speed of stirring, to determine the larger torque of the motor at that speed to prevent overload. The choice of motor should be concerned with torque, not power. Motors of the same power, at the same speed, do not necessarily have the same torque, especially AC motors and DC motors, which vary greatly. In the case of a single motor, the larger torque is not the same at different speeds. The larger torque of the selected hydrogenation reactor motor should be more than 1.5 of the larger torque required for the stirring reaction to be safe, and also to ensure that the footsteps are always carried out at the required speed.
    b、 the principle of economic suitability. For example, if the speed is not high, you can choose a reducer motor; and choose a more powerful motor then use a frequency converter to adjust the speed down. This can save costs.
c、Good heat exchange performance. 
d、High mass transfer efficiency. 
e, High temperatures and corrosion resistance.
f、Sanitary, no environmental contamination. Internal take mirror polishing, to ensure no sanitary dead ends, fully enclosed design to ensure that the material is always in aseptic condition, the nominal surface can choose sandblasting, sandblasting, cold-rolled original color matte treatment.
g、Heating method can choose steam, electric heating, or heating oil.
h, Do not need boiler active heating, the use of the advantages of convenience.
i, Easy to install and maintain.

FAQ on the Hydrogenation reactor

Q: Why is safety important in hydrogenation reactors?

A: Safety is extremely important in hydrogenation reactors for two main reasons. Firstly, it helps to keep the air quality in the lab from getting worse. And secondly, it ensures the well-being of the workers since there's a risk of potential explosions.

 

Q: Why do we vent the pressure relief port of the hydrogenation reactor to the outside?

A: The pressure relief port is vented outside to safely release any leaked hydrogen during the reaction. Hydrogen is flammable and explosive, and venting it outside reduces the risk of explosions or fires inside the reactor.

 

Q: How does venting the pressure relief port prevent hydrogen buildup in the room?

A: To improve safety, it is vital to locate the pressure relief vent outside the room. This prevents hydrogen from building up in the room, especially higher up in the room, where it can form dangerous mixtures and potentially cause explosions. By taking this precaution, we ensure the safety of everyone involved in the process.

 

Q: How does venting the pressure relief port protect the people working with the reactor?

A: When it comes to protecting reactor personnel, venting the pressure relief ports plays a crucial role. If there's a pressure buildup, these vents allow the gas to escape through an outdoor vent first, giving the operator enough time to safely get away. This measure significantly reduces the risk of injury, ensuring the well-being of the personnel working with the reactor.

 

Q: What aspects of the reactor components do we need to consider when shopping?

A: It is recommended that customer service should try to consider the impact of sharp pressure changes on the reactor components when we are shopping, so that we can configure the reactor with related devices, for example, the high-pressure heat exchanger.

 

Q: What are ceramic balls used for in the reactor?

A:  The balls at the bottom of the reactor act as a support for the catalyst, preventing it from being carried out of the reactor, while those at the top are a covering material to improve the distribution of the oil and hydrogen and to prevent deviation. There are also "activated ceramic balls" with a small amount of catalyst active ingredient with a small amount of catalyst reactivity (e.g. inert alumina ceramic balls), which can also be called catalyst additives. Their main function is to increase the gas or liquid distribution point, support and protect the active catalyst with low strength.

Q: What quality requirements do ceramic balls need to meet?

A: Ceramic balls need to meet specific quality requirements, such as handling temperature changes up to 2800 °C and passing rapid decompression tests at a rate of 99% or higher.
