The difference between the application of different reaction kettle

Reactor is an indispensable core equipment in chemical production, and its application range is extremely wide, covering synthesis, catalysis, separation and other fields. Due to the differences in design, structure and performance of different reactors, their application scenarios are also significantly different. This paper will analyze the differences in actual production of different reactors in detail from the classification, application characteristics, advantages and disadvantages of the reactors.

1. differences classified by reaction mode

according to the reaction type, the reactor can be divided into constant volume reactor and batch reactor. The main feature of the constant volume reactor is that there is no liquid release, so special attention should be paid to the collection of liquid during operation, and it is usually equipped with a liquid level control device. The batch reactor can be seamlessly connected with other equipment in the production process, which is convenient for automatic control.

Differences in classification of 2. by reaction medium

according to the different reaction medium, the reaction kettle can be divided into solid state reaction kettle and liquid reaction kettle. Solid-state reactors are usually used for the reaction of granular materials, such as the grinding and mixing of powdered raw materials, and are characterized by short reaction time and high efficiency. The liquid reactor is suitable for the reaction of liquid preparations, such as the mixing and reaction of the solution, usually requires a larger reaction space to ensure the uniformity and control of the reaction.

3. difference controlled by reaction temperature

the temperature control of the reactor is one of the key factors in the selection. High-temperature reactors are usually used for the polymerization of polymer materials, such as polyesters, polyamines, etc. This type of reaction requires very strict temperature control, and a slight deviation may lead to reaction failure. The low-temperature reactor is suitable for catalytic reactions, such as esterification reaction, dehydration reaction, etc., usually need to accurately control the reaction temperature to ensure the catalytic efficiency of the reaction.

4. differences controlled by reaction time

reaction time is also an important factor to consider when selecting a reactor. For enterprises with high production scale requirements, it is necessary to complete the reaction in a short time, which means that it is necessary to choose a reactor with short reaction time and high efficiency. Smaller companies can accept longer reaction times to improve the utilization of raw materials for the reaction.

5. by difference in reaction efficiency

reaction efficiency is an important indicator to measure the performance of the reactor. For enterprises that require high yield, it is necessary to choose a reactor with high reaction efficiency. Reactors with high reaction efficiency usually have good mixing uniformity and heat exchange performance, and can complete the reaction in a short time, thereby improving production efficiency.

6. by reaction environment difference

the reaction environment is one of the factors that need to be considered when selecting a reactor. In the special environment of high pressure, high vacuum, high temperature and high humidity, it is particularly important to choose the right reactor. For example, in the vacuum reaction, it is necessary to select a reaction kettle with vacuum Descaling capability; in a high vacuum environment, it is necessary to select a reaction kettle with good sealing performance.

7. differences by scale of response

the reaction scale is one of the factors that need to be considered when selecting the reactor. For large-scale production, it is necessary to choose a large-volume reactor to improve the efficiency and yield of the reaction. Small-scale production can choose small-volume reactions to reduce equipment costs.

8. differences in the degree of automation by reaction

with the improvement of the degree of automation, the intelligence of the reactor has become an important criterion for selection. For example, precise control of reaction conditions can be achieved by installing automated control equipment, thereby improving reaction efficiency and product quality.

9. Variance by Response Cost

the cost of the reactor is one of the important factors to consider when choosing a user. Different reactors have different costs, including initial investment costs and operation and maintenance costs. Therefore, when choosing a reactor, it is necessary to consider the relationship between cost and performance in order to achieve the best economic results.

The differences in the application of different reactors are mainly reflected in the reaction mode, reaction medium, temperature control, reaction time, reaction efficiency, reaction environment, reaction scale, degree of automation and reaction cost. Choosing the right reactor needs to take these factors into account according to the specific production needs, in order to achieve the high efficiency, safety and economy of the reaction.
