Who can explain what the downstream product chain of ethylene includes?

C4 products: MTBE, MMMA, butene-1, high-purity isobutylene. C5 products: isoprene, C5 resin. Oxide-containing products: ethylene glycol, propylene glycol, polyols. Styrene, polystyrene, expanded polystyrene.

Thank you. Could you be more detailed? There should be vinyl chloride, polyethylene, and polypropylene, right?

The main products of ethylene cracking distillation are: C2 ethylene and C3 propylene; in addition, C4 and C5 are produced in the butadiene unit as a by-product of ethylene production； Aromatic hydrocarbons workshop (benzene, toluene, xylene, C9) C6 ； MTBE Workshop (Methyl tert-butyl ether) – Downstream: Styrene Plant: Benzene + Ethylene ； Plastic factory: polyethylene, polypropylene ； Petroleum resin plants: C5 resin (pentene, using C4 and C5 alkanes as solvents, with AICI3 as catalyst); C9 resin (C9). Butadiene rubber plants: The main raw material is butadiene ； Other chain products: 1. Production of phenol and propylene from benzene + propylene ； Phenol is an important raw material in the organic chemical industry, mainly used in the production of phenolic resins, caprolactam, bisphenol A, adipic acid, aniline, alkyl phenols, salicylic acid, and others ； 2. Phenol + propylene to produce bisphenol A ； 3. Production of polycarbonate (PC) resin from bisphenol A + methanol ； 4. Production of caprolactam (CPL) using benzene as the main raw material ； It is mainly used to produce nylon 6 engineering plastic (accounting for 90%) and synthetic fiber (nylon) 5, as well as methyl methacrylate (MMA) using methyl tert-butyl ether as a raw material ； An important raw material in organic chemistry, mainly used in the production of plexiglass, and can also be used to manufacture other resins and plastic modifiers. 6. Production of ABS resin from styrene, acrylonitrile, and butadiene ； 7. Producing aniline using benzene as the main raw material ； Aniline is an important organic chemical raw material that can be used to produce a variety of products such as MDI, dyes, organic pigments, rubber processing aids, pesticides, pharmaceuticals, and intermediates for fine chemicals. 8. Production of diphenylmethane diisocyanate (MDI) from aniline + dimethyl carbonate ； Diphenylmethane diisocyanate (MDI) is a key raw material for producing polyurethanes. Polyurethane products possess the advantages of both plastics and rubbers. 9. Production of butyl octyl alcohol from propylene + hydrogen ； Butanol and octanol are important raw materials in the fine chemical industry, with a wide range of applications. Butanol can be used as a solvent for the production of plasticizers such as dibutyl phthalate (DBP) and butyl benzyl phthalate (BBP), as well as chemicals like butyl acetate and butyl methacrylate. 10. Production of polyester from phthalic acid + ethylene glycol ； The main use of polyester for bottles is to produce packaging materials for food and beverages. 11. Production of epoxy resin from epichlorohydrin + pure benzene + bisphenol A ； 12. Production of chlorinated polyethylene (CPE) from high-density polyethylene + chlorine gas ； CPE is a polymer-based waterproof material with a wide range of applications; it features good weather resistance, resistance to deformation, aging resistance, and tensile strength, and can be used in temperatures ranging from -20°C to 80°C. 13. Acetic acid (99.5 wt%) + ethylene (chemical grade) to produce vinyl acetate ； 14. Production of polyvinyl alcohol from vinyl acetate ； Wait! That’s why so much ethylene is produced!

When will the large ethylene plant in Fushun begin operations? Does the current situation have an impact on it?

Thank you, it’s so detailed; you’re an expert! Upstairs, the Fushun project has been in progress for half a year now

I learned it; it’s very useful. . . .
