Oil refining and chemical industry, as an important part of China's energy industry, has a very clear and mature industrial chain. According to statistics, China can produce more than 60,000 (kinds) of chemical products at present, and the upstream and downstream links are close, the industrial chain is extremely complex.

Tracing back to the source, the starting point of the refining and chemical industry is crude oil. However, as there are more than 2,000 varieties of crude oil in the world, the nature of crude oil of different varieties varies greatly, and there will be some differences in the processing equipment and process.

Crude oil through the first and second processing units to produce in line with the national standards of gasoline, diesel, aviation kerosene, naphtha, liquefied gas and other products, this is the direction of refining.

As the refining plant continues to process its products, it moves towards the direction of chemical industry, which can be divided into three main paths:

1. Aromatics path: the final chemical products are industrial plastics, plexiglass, synthetic detergent, polyester fiber, coating, polyimide, etc.

2. Ethylene path: the final products are lithium ion battery diaphragm material, engineering plastics, styrene butadiene latex, synthetic leather, resin, coating adhesive, polyethylene, solvent, etc.

3. Lubricating oil path: the final products are lubricating oil, plate wax, grain wax, white oil and so on.

Typical refinery installations:

The device that changes crude oil into gasoline, diesel, aviation kerosene, naphtha and liquefied gas in line with national standards is called a refining device.

At present, the main oil refining installations in China include: atmospheric and vacuum units, catalytic cracking units, hydrotreating units, hydrocracking units, catalytic reforming units, aromatic joint units, delayed coking units, s-zorb adsorption desulfurization units, alkylation units, hydrogen production units, desulfurization, solvent regeneration units, etc.

Typical chemical plant:

The chemical plant is located in the downstream of the refinery plant and is often named after the product. Typical chemical plants are: Ethylene (Ethylene), PE (Polyethylene), pp (Polypropylene), p-xylene/purified terephthalic acid (PTA) (PX/PTA), Butadiene (Butadiene), epoxy ethane/Ethylene glycol (EO/EG), bisphenol A (Bispheno - A), methyl tert-butyl ether (MTBE), Synthetic Rubber, Synthetic Rubber), vinyl acetate (Vinegar Ethylene) glycol, propylene oxide (PO), the Syngas system (Syngas The To Glycol), propane dehydrogenation (PDH) and carbon separation device (C5), etc.

Through the above elaboration, I believe that you have a clearer understanding of the oil refining and chemical industry chain, if you want to know more about the oil refining and chemical knowledge, you can call yueyang Sciensun chemical co., LTD through this site.
