Chemical engineering, that is, chemical engineering, refers to the use of chemical principles, chemical phenomena, chemical processes and related technical means for the production of products or energy, transformation and processing of science and technology. From the current production and life, we can find that the chemical industry has covered many fields such as chemical products, petroleum, coal chemical industry, fine chemical industry, biochemical industry and so on, and has become one of the most important and basic fields in modern industry. The emergence and development of
chemical industry in

chemical industry originated in the very early stage of human development, such as the Byzantine Empire, when there was a chemical process for manufacturing glass, dyes, spices and other products. During the industrial revolution of the 19th century, the chemical industry developed rapidly, and the research and development of new materials became increasingly important. The research and development of chemistry provided a solid foundation for industrial production.

the 20th century, the chemical industry has continued to grow, not only in terms of technology and talent has been continuously enhanced, but also in modern science, production and environmental protection and other aspects have made significant contributions. During this period, chemicals were widely used in medical, pharmaceutical, food, plastics and other industries. After the Second World War, because the country's support for the chemical industry promoted the development of the chemical industry, so that the chemical industry has become one of the important industries in the world.

the application and role of chemical industry

Today, the chemical industry has become an indispensable cornerstone of global industrial, economic and social development, covering too many industries, such as:

1, energy industry: oil, natural gas and so on are an important part of the earth's resources, the chemical industry plays an important role in energy development and utilization.

2. Metallurgical industry: Chemical technology is also often used in metallurgical industry, such as the production of paper, cement, ceramics and other products.

3. Food industry: In the food industry, chemical technology has been widely used, such as the production of dairy products, alcohol, sweeteners, foaming agents, and other beverages and dietary products.

4. Pharmaceutical industry: Chemical preparations are the main products in the field of medicine, including chemical synthesis, biotechnology, preparation technology, etc.

5. Environmental protection industry: The chemical industry is one of the major pollution sources, but at the same time, chemical technology also develops new technologies and equipment to promote the development of environmental protection industry.

the main trends in the development of the chemical industry

According to today's development trends, the future of the chemical industry will present three main directions:

1. Green chemistry: Green chemistry is one of the concepts in the field of chemistry, which proposes solutions to reduce or eliminate pollution and promote harmlessness to the ecosystem. Green Chemistry takes environmental issues as an opportunity to promote the development of more environmentally friendly products and processes to promote sustainable manufacturing.
