What is the difference between fine chemicals and petrochemicals, as well as coal chemicals?
My personal opinion: The petrochemical and coal chemical industries can be regarded as a category with similar products but different raw materials, while the fine chemical industry can be seen as an extension of the further processing of the products from these two industries. Provide a more detailed explanation of that treasure map from Hai Chuan!
The common point among the three is that they are all chemical processes aimed at producing chemicals. Differences: The raw materials used in the three are somewhat different; coal chemical industry uses coal as a raw material to produce chemicals ； Petrochemical industry is the process of producing petrochemical products using certain products/intermediates from the oil refining process as raw materials ； Fine chemical manufacturing is the process of producing fine chemicals using certain chemicals/intermediates as raw materials. There is a certain degree of commonality in the production of certain products in coal chemical and petrochemical industries.
The Chinese language is profound and complex; for each character and word, there are different interpretations offered by various people, with many possible meanings. The same is true for the precise classification of industries and enterprises; different organizations and different handlers will provide you with varying classifications. Returning to the topic, in one sentence: “You are in me, and I am in you.””
Coal chemical and petrochemical industries are part of the large-scale chemical industry; investments in these fields range from hundreds of millions to several billion dollars. They require large amounts of energy and have high explosive power. Fine chemical industries, on the other hand, use less energy and have lower explosive power. It’s hard to say exactly how much investment is needed for such industries; projects can be carried out with investments in the tens of thousands. Investments in producing high-end materials amount to hundreds of billions as well
I feel my interpretation is more appropriate; **the management policies for the petrochemical and fine chemical industries differ, and those that can be classified as part of the fine chemical industry are those whose potential harm to the public is lower compared to petrochemical and coal chemical industries. Equipment and pipelines for petrochemical and coal chemical processes are generally large in size; containers have a capacity of several hundred cubic meters, storage tanks have a capacity of several thousand cubic meters, and pipes have a diameter of several hundred millimeters. Containers in fine chemical industry range from a few hundred liters to several cubic meters; storage tanks have capacities of several cubic meters, while pipes are smaller than 100 mm in diameter.
