Read： 501 Time：13months ago Source：Transform the World with Simplicity

With the development of modern industry, oxygen, as an important industrial gas, plays a vital role in the industrial production process. The wide application of oxygen has brought great economic and social benefits, and its industrial production method is becoming more and more mature. This article will introduce the principle and application of industrial oxygen production method in depth. Readers who are interested in industrial oxygen production process can read the following contents in depth.

1. of oxygen industrial process principle

of the industrial method of manufacturing oxygen mainly includes the separation of air at room temperature, low temperature separation of air and gravimetric method. Below we will introduce the principle of these three industrial oxygen production methods.

1. Air separation method at room temperature

The air separation method at room temperature uses the characteristics of air to separate oxygen and nitrogen from the air. At room temperature, air is composed of nitrogen, oxygen and other gases, of which nitrogen accounts for 78% of air, while oxygen accounts for 21%, and the rest of the other gases account for about 1%.

In the process of making oxygen, air is compressed and then passed through a separator. The separator is a special device that separates nitrogen and oxygen through a multi-layer separation membrane to obtain high-purity oxygen.

2. Separation of air at low temperature

The principle of the separation of air at low temperature is to separate oxygen and nitrogen from air through liquefaction technology. Among them, the main process of oxygen production is to pass the compressed air through the separator and liquefy it under low temperature conditions to obtain high-purity oxygen.

3. Gravimetric method

gravimetric method is to pass the air through a special pure metal container, and the nitrogen and oxygen in the air are exported from the bottom of the container, so as to realize the manufacture of oxygen. This process has a very wide range of applications in the manufacture of high purity oxygen. Industrial Application

of

2. Oxygen With the continuous development of modern industry, the scope of application of oxygen is also widening, so far, the application of oxygen related to iron and steel manufacturing, mineral mining, chemical manufacturing and other fields. Now let's look at the areas in which oxygen has a wide range of applications.

1. Iron and steel manufacturing

In the iron and steel manufacturing process, oxygen as an important oxidant, its application is very extensive. By injecting oxygen into the steel furnace, impurities in iron ore can be removed, so that the quality of steel can be improved, so as to meet the needs of the market.

2. Mineral mining

In the process of mineral mining, oxygen also has a wide range of applications. By injecting oxygen into the mine, the process of ore oxidation can be accelerated, thereby increasing the efficiency of mineral extraction.

3. Chemical manufacturing

In the field of chemical manufacturing, the application of oxygen has reached its peak. In some manufacturing processes, an oxygen component is required for the oxidation reaction to produce the desired product. In addition, oxygen can also stabilize certain reactions and ensure the quality of the product.

This article provides an in-depth introduction to the principles and applications of oxygen industry, from which readers can learn about the importance of oxygen in modern industry and how it is widely used in the manufacture of various products. It is hoped that this article will help people have a deeper understanding of the oxygen industry method.
