What are the dozen or so devices supporting the downstream production of one million tons of ethylene? What is the typical scale?

The EO device is generally 200,000 tons, and can be as large as 300,000 tons, and the supporting ethylene glycol is 300,000 to 400,000 tons.； The total amount of polyethylene is about 600,000 tons

There are styrene, butadiene extraction, ethylene glycol, acryl cyanide, MTBE/butene-1, HDPE, LLDPE, PP, butyl octanol, phenol/propylene, etc.

The project includes 10 sets of production equipment, the main 4 sets of production equipment adopt foreign technology, namely: 1 million tons/year ethylene plant, using cooperative technology between Sinopec and the American company ABB LUMMUS ； 650,000 tons/year ethylene oxide/ethylene glycol (EO/EG) unit, using technology from the American DOW Chemical Company ； 285,000/620,000 tons/year propylene oxide/styrene (PO/SM) unit, using the technology of American LYONDELL company, established a joint venture company ； The 450,000 tons/year polyethylene (LLDPE) plant adopts the technology of the American UNIVATION company. The other six sets all use Sinopec's own technology, specifically a 700,000 tons/year pyrolysis gasoline hydrogenation unit, a 600,000 tons/year aromatics extraction unit, a 650,000 tons/year ethylbenzene (EB) unit, a 300,000 tons/year polypropylene (PP) unit, a 11/40,000 tons/year MTBE/butene-1 unit, and a 160,000 tons/year butadiene unit.

The downstream supporting equipment of the 1 million tons ethylene plant also needs to look at the product market and product solutions to determine the type and capacity of the equipment. For example, among my country's existing ethylene plants, Maoming and Shanghai ethylene are mainly plastic-based, Jilin ethylene is mainly chemical-based, Yangzi ethylene is mainly chemical-fiber type, and Beijing Yanshan, Huizhou ethylene, and Tianjin ethylene are mainly plastic and chemical. Of course, it is not absolute. For example, Maoming Ethylene also produces ethylene glycol, but it will not continue to support benzene (PTA, etc.). As mentioned in the fourth floor, it is very specific. For example, ethylene can be produced to produce polyethylene or ethylene glycol. I used to work in Maoming Ethylene and I know about the ethylene glycol/ethylene oxide device. Sometimes ethylene oxide is rarely produced. At present, there are many supporting plastic devices for the 1 million tons ethylene plant, and the national market is somewhat saturated. The further development of Maoming ethylene can only start from the aspect of chemical fiber raw materials.

There is also PetroChina Ethylene.

There are two main domestic ethylene engineering companies, Sinopec Engineering and Construction Company and PetroChina Global Engineering Company. In addition, Shanghai Wison Engineering Company mainly engages in ethylene cracking. It is a private enterprise but has a deep background. It often does general contracting, such as Lanzhou ethylene downstream equipment. There are many institutes. The following summary mainly includes PetroChina Daqing Design Institute, Jilin Chemical Design Institute, Global Engineering Company, Sinopec: Shanghai Engineering Company, Ningbo Engineering Company (formerly Lanzhou Design Institute), Sinopec Engineering Construction Company
