Plastic Production Process: From Crude Oil to Common Polymers #108172 (License: Personal Use)

This diagram illustrates the integrated petrochemical process where crude oil undergoes refining (e.g., naphtha extraction) and steam cracking to yield foundational olefins and aromatics-ethylene, propylene, and benzene. These intermediates then enter specialized reactors for functionalization (e.g., chlorination to vinyl chloride) or direct polymerization, forming major synthetic polymers including PVC, polyethylene, polystyrene, and polypropylene. Each pathway includes structural formulas and process labels in French, highlighting both chemical transformations and industrial scale operations.

Used in educational, technical, or sustainability-focused web content explaining plastic origins, circular economy challenges, or chemical engineering curricula; targets students, engineers, policymakers, and environmentally conscious consumers seeking transparency on material lifecycles.
