Petrochemical engineering refers to the systematic engineering of extraction, processing, storage and transportation of petroleum, natural gas, and chemical raw materials, as well as the production of chemical products. Its core links include raw material refining, construction of chemical reaction units, allocation of storage and transportation facilities, installation of process pipelines, and safety and environmental management. Petrochemical engineering is widely applied in the fields of petroleum refining, natural gas processing, chemical production, and fine chemicals. It serves as an important pillar of the energy and chemical industry chain, providing key raw materials and power support for industrial development.
