The difference between reaction kettle and reaction tank

In the field of chemical production, reaction kettle and reaction tank are two kinds of widely used equipment, mainly used for liquid or solid-liquid reaction. Although the two are similar in basic principle, there are significant differences in specific structure, operation mode, application and so on. This article will analyze the difference between reactor and reactor in detail from multiple angles to help professionals in the chemical industry better understand the characteristics and application scenarios of these two types of equipment.

1. Overview: Basic Concepts of Reactors and Tanks

1. the basic concept of the reaction kettle The reactor is a fully closed container, the internal is usually equipped with stirring mechanism and heating system (such as electric heating, oil heating or steam heating). Its main function is to provide a constant temperature environment to ensure the efficient progress of chemical reactions. The volume of the reactor is usually large, which can accommodate a large reaction system, and is suitable for industrial reactions that require high efficiency and high temperature control.

2. Basic concept of reaction tank The reaction tank is also a fully closed container, but compared with the reaction kettle, its structure is simpler, usually only by the tank and lid, no additional stirring or heating device inside. The reaction tank usually relies on natural convection heat transfer, and temperature control depends on ambient conditions. Its small size makes it suitable for experimental reactions in laboratories or small factories.

Characteristics: comparison of structure, operation mode and applicable scenario

1. structural Design

• reaction kettle: Due to the high temperature and rapid reaction of equipment, the reactor is usually designed as a multi-layer structure, including a reaction layer, an insulation layer and a partition. Stirring mechanisms and heating systems are usually installed at the top or bottom of the reactor to ensure reaction uniformity and thermal energy transfer efficiency.
• Reaction tank the structure of the reaction tank is relatively simple, usually only a cylindrical metal or plastic container. Due to the lack of additional stirring and heating equipment, the temperature control of the reaction tank depends on an external heat source or environment.

1. Operation mode

• reaction kettle: The operation of the reactor is more complicated, and it is usually necessary to remotely adjust the temperature, pressure and stirring speed through the control panel or computer system. Because of its larger size, operators may rely more on automated equipment.
• Reaction tank: The operation of the reaction tank is relatively simple, usually only manual adjustment of the external heat source or adjustment through a simple control panel. Its operators are less, mostly technicians or engineers.

1. Application occasions

• reaction kettle the reactor is suitable for liquid or solid-liquid reactions in large-scale industrial production, such as large-scale reaction devices in petrochemical, pharmaceutical, environmental protection and other industries. Its high efficiency and stability make it the core equipment in chemical production.
• Reaction tank reaction tanks are mostly used for laboratory research or production in small factories, such as chemical reaction experiments in university laboratories, or small-scale production in small factories. Its simple structure and low cost make it suitable for initial experiments and small-scale applications.

3. performance characteristics: efficiency, safety and energy saving comparison

1. reaction efficiency

• reaction kettle: Due to its powerful stirring and heating capabilities, the reactor can significantly improve the reaction efficiency, especially under high temperature or high pressure conditions. The design is usually effective to avoid coking of reactants and reaction non-uniformity.
• Reaction tank: The reaction efficiency of the reaction tank is low because it relies on natural convection heat transfer and is susceptible to the risk of uneven temperature distribution and reactant coking.

1. Security

• reaction kettle: Due to the need to strictly control the temperature and pressure, the safety of the reactor is higher. The design usually includes multi-level insulation measures and multiple safety protection devices (such as temperature over-limit alarm, pressure relief valve, etc.).
• Reaction tank: The safety of the reaction tank is low because it lacks additional protection devices and is susceptible to interference from the external environment, such as sudden temperature changes or pressure fluctuations.

1. energy saving

• reaction kettle: The energy consumption of the reactor is high due to the need for an additional heating system. But by optimizing the design and control technology (such as energy-saving heating system), its energy consumption can be effectively controlled.
• Reaction, Tank: The energy consumption of the reaction tank is low because it relies on natural convection heat transfer, but its efficiency is low, resulting in low overall energy efficiency.

4. selection basis: how to choose the reaction kettle and reaction tank

in chemical production, the choice of reaction kettle or reaction tank, need to consider the following factors:

1. scale of production

• large-scale industrial production usually requires reactors because they can handle larger reaction systems; laboratories or small factories often use reaction tanks.

1. reaction temperature and pressure

• high temperature and high pressure reaction usually requires a reaction kettle, because it has high temperature control ability and perfect insulation system; and the reaction tank is mostly used in the laboratory at room temperature or low pressure reaction.

1. Reaction efficiency and performance requirements

• high efficiency and high stability requirements of industrial reaction multi-choice reactor; and the laboratory on the efficiency of less demanding experiments more use of reaction tank.

1. Space and cost constraints

• if the space is limited and the budget is limited, the reaction tank can be selected; and if higher performance and larger reaction scale are required, the reaction kettle must be selected.

5. summary: the difference and choice of reaction kettle and reaction tank

reaction kettle and reaction tank are two different equipments in chemical production, and there are significant differences in structure, performance and application. The choice of equipment needs to be considered according to the specific production scale, temperature control requirements, reaction efficiency and cost budget. Understanding the difference between these two types of equipment will help chemical practitioners choose the right equipment more efficiently, thereby improving production efficiency and product quality.

Through the detailed analysis of this article, I believe readers have a clear understanding of the difference between the reactor and the reaction tank, and how to make a reasonable choice of equipment in actual production. It is hoped that the content of this paper can be helpful to professionals in the chemical industry.
