The application and properties
of industrial gases in the field of raw materials for chemical production
Abstract

This paper introduces in detail the application and properties of industrial gases in the field of raw materials for chemical production. Through the discussion of the properties, preparation, transportation and storage of various common industrial gases, the important role of them in the production process of chemical products is expounded. At the same time, this paper also discusses the safe use of industrial gases and environmental protection requirements to ensure the smooth progress of chemical production.

1. Introduction

industrial gases are important raw materials in the production process of chemicals and are widely used in various fields. They have unique physical and chemical properties that are critical to the quality and efficiency of chemical production. Therefore, it is of great significance to understand and master the nature, use and safety and environmental protection requirements of various industrial gases for improving the production level of chemical products.

2. the nature and use of common industrial gases

1. Oxygen

Oxygen is a colorless, odorless, non-toxic gas with a high degree of oxidation. In the production of chemical products, oxygen is mainly used for oxidation reactions, such as synthetic ammonia, ethylene oxidation to acetaldehyde, etc. In addition, oxygen is also used in combustion, cutting, smelting and other processes.

2. Nitrogen

Nitrogen is a colorless, odorless, non-flammable gas with good stability and oxidation resistance. In the production of chemical products, nitrogen is often used as a protective gas to prevent oxidation of substances in contact with oxygen. In addition, nitrogen is also used in the synthesis of ammonia, the preparation of nitric acid and other processes.

3. Hydrogen

Hydrogen is a colorless, odorless, flammable and explosive gas with a high degree of reducibility. In the production of chemical products, hydrogen is mainly used for reduction reactions, such as oil hydrogenation, benzene hydrogenation and so on. In addition, hydrogen is also used in the synthesis of ammonia, the preparation of methanol and other processes.

4. carbon dioxide

carbon dioxide is a colorless, odorless gas, soluble in water, acidic. In the production of chemical products, carbon dioxide is often used in the preparation of urea, sodium carbonate and other chemical products. In addition, carbon dioxide can also be used for fire extinguishing, refrigerant, etc.

3.

for the preparation, transport and storage of industrial gases In order to ensure a stable supply of industrial gases in the production of chemicals, it is necessary to understand the requirements for their preparation, transport and storage. The preparation methods of various industrial gases are different. For example, oxygen is mainly prepared by air separation, and nitrogen can be prepared by air separation or nitride decomposition. In the process of transportation, it is necessary to choose the appropriate mode of transportation according to the nature of the gas, such as compressed gas is usually transported by steel cylinder. When storing industrial gases, the relevant regulations should be strictly observed to ensure the safety and reliability of storage facilities.

4. the safe use of industrial gases and environmental protection requirements

in the chemical production process, should pay attention to the safe use of industrial gases and environmental protection requirements. First of all, operators need to be professionally trained to understand the nature of various industrial gases and safe operating procedures. Secondly, the production process should strictly abide by relevant regulations and standards to ensure the safety and hygiene of the production environment. Finally, waste gas treatment and waste recycling should be strengthened to reduce the impact of the production process on the environment.

5. conclusion

industrial gases are widely used in the field of chemical production raw materials, and play an important role in improving the quality and efficiency of chemical production. Understanding and mastering the nature, use and safety and environmental protection requirements of various industrial gases will help to improve the level of chemical production and promote the sustainable development of the chemical industry.
