Chemical industry is to change the structure, composition and form of substances through chemical reactions to produce chemical products needed by people, is an important industrial category in the national economy. As a new and efficient extraction technology, centrifugal solvent extraction technology has the green characteristics of high extraction efficiency, extractant recycling, low power consumption, etc., and is widely used in various fields of the chemical industry to support the high-quality development of the chemical industry. With its excellent performance, the combined extraction centrifugal extractor has shown great application potential in many segments.

1. Applications in the field of petrochemical industry **

In the field of petrochemical industry, centrifugal solvent extraction technology is widely used in oil extraction, organic compound classification and multi-component mixture separation. Take 2-ethylanthraquinone as an example, this important intermediate is widely used in dyes, pigments and photosensitive materials. The production process is usually divided into two steps, namely the preparation of anthraquinone and the ethylation reaction. In the process of ethylation reaction, the reaction products were separated and extracted by the centrifugal solvent extraction process of 4-stage extraction, 2-stage alkali washing and 2-stage water washing. The combined extraction centrifugal extractor plays a key role in this process, and its efficient separation performance and resistance to strong acid corrosion ensure that the content of 2-ethylanthraquinone in the raffinate is as low as ppm, and after refining and drying, the final product with high purity of 2-ethylanthraquinone is obtained.

The combined extraction centrifugal extractor uses fluorine material sprayed on steel base, which greatly improves the corrosion resistance of strong acid. In addition, its high separation factor and excellent separation effect make the production process more efficient and economical. The equipment is also designed with input cost optimization in mind, making it an ideal choice for the petrochemical sector.

** II. Technical advantages of combined extraction centrifugal extractor **

The combined extraction centrifugal extractor not only performs well in the field of petrochemical industry, but also has extensive application potential in other fields of chemical industry. Through innovative structural design and efficient centrifugal separation principle, the combined extraction centrifugal extractor can solve a variety of complex separation and extraction problems. The following are some of the key technical advantages of the combined extraction centrifugal extractor:
