The nature and use
of low pressure membrane in the field of chemical production raw materials
1. Introduction

In the field of chemical production raw materials, low pressure membrane is an important separation technology, widely used in various chemical processes. Low pressure membrane has excellent separation performance and physical and chemical stability, which plays an important role in improving the production efficiency and product quality of chemical products. This article will detail the properties and uses of low-pressure films.

2. The properties of low-pressure membranes

1. High separation efficiency: Low-pressure membranes have high separation efficiency and can effectively separate substances of different molecular weights to achieve fine separation of substances.
2. Good physical and chemical stability: low pressure film has good acid resistance, alkali resistance, oxidation resistance and other properties, can be stable in the harsh chemical environment.
3. Energy saving and environmental protection: The low-pressure membrane separation process does not need to add chemical reagents, and will not produce secondary pollution, which meets the requirements of energy saving and environmental protection.

3. the use of low pressure membrane

1. separation and purification of chemical raw materials: low pressure membrane can be used for the separation and purification of chemical raw materials, such as hydrocarbon separation in petrochemical industry, protein separation in biological medicine, improve the purity and yield of products.
2. wastewater treatment and reuse: low pressure membrane can be used for wastewater treatment and reuse, to achieve water conservation and environmental protection. Through the filtration of low pressure membrane, the harmful substances in the wastewater are removed, so that the treated water quality can meet the reuse standard.
3. Concentration and desalination of substances: Low-pressure membranes can be used for concentration and desalination of substances, such as seawater desalination, juice concentration, etc., to achieve efficient separation and concentration of substances.

4. application case

a chemical enterprise needs to produce a high purity chemical raw material in the production process. In order to improve the purity of the product, the company adopted low-pressure membrane separation technology. Through the filtration of the low-pressure membrane, the impurities in the raw materials are effectively removed, the purity of the product is increased by more than 30%, and the production cost is reduced.

5. conclusion

low pressure film has a wide application prospect in the field of chemical production raw materials, which can improve the purity and yield of products, reduce production costs, and meet the requirements of energy saving and environmental protection. With the continuous development of science and technology, low-pressure membrane technology will continue to progress, bringing more innovations and breakthroughs in the field of chemical production.
