Cooling and Heating Systems in the Hydrothermal Autoclave Reactor

Contact us today for the perfect temperature control solution

Cooling and heating systems in the hydrothermal autoclave reactor are heating equipment that uses water as the heat transfer medium. It uses water’s characteristics of large specific heat and fast heat transfer to transfer heat to the object being heated. In industrial production, water is widely used as a coolant and solvent in chemical processes.

For example: petroleum cracking gas to produce ethylene; methanol dehydration to produce formaldehyde; caustic soda production in the chlor-alkali industry, etc.

Hydrothermal autoclave reactors widely used in the chemical industry mainly include the following types: tubular heat exchangers; tube and tube heat exchangers; plate heat exchangers and spiral plate heat exchangers; sleeve and jacket types Hybrid heat exchangers; circulating fluidized bed reactors with internal cooling and external heating; fixed bed reactors and other types of special structure hydrothermal autoclave reactors, etc.

Cooling and heating systems in the hydrothermal autoclave reactor

1. Natural cooling

The natural cooling method of hydrothermal autoclave reactor is to allow the kettle body to naturally dissipate heat. When the reaction is completed, turn off the heater and stirrer and allow the kettle to cool naturally. This method is suitable for situations where the reaction temperature is not too high. Generally, the temperature can be lowered to below room temperature, but it takes a long time and requires patience.

2. Water cooling

Water cooling is a common cooling method and one of the faster and more effective methods. The specific operation method is: after the reaction is completed, first turn off the heater and stirrer, then connect the cooling water pipe, flow the cooling water into the reaction kettle through the cooling jacket, and circulate the cooling until the temperature of the kettle body drops to the required temperature.

It should be noted that when using water cooling, pay attention to the flow and temperature of the water to avoid problems of too low or too high temperature. In addition, use high-quality cooling water to avoid negative effects on the reaction.

3. Air cooling

Gas cooling is a cooling method suitable for high temperature reactions. The specific operation method is: after the reaction is completed, turn off the heater and stirrer, then flow the inert gas (such as nitrogen) into the reaction kettle through the cooling jacket, and circulate the cooling until the kettle temperature drops to the required temperature.

It should be noted that when using gas exhaust, prevent gas leakage and maintain good ventilation. At the same time, use high-quality inert gases and avoid adverse effects on the reaction.

In short, different cooling methods can be selected according to the needs of different reactions. At the same time, ensuring the normal operation of the reactor equipment also requires regular maintenance of the equipment.
