This document provides an overview of the petrochemical industry process. It begins with raw materials like crude oil, natural gas, and associated gases that are processed in refineries. Key intermediate products like ethylene, propylene, and benzene from cracking units then become feedstocks for petrochemical plants. These are converted into chemical building blocks and derivatives that have many applications in everyday products like plastics, fibers, cleaners, paints and coatings. The petrochemical industry enhances materials and plays a role in innovations for renewable energy, infrastructure, healthcare, and more.
