Petrochemicals are chemicals other than those used as fuels that are derived from crude oil or natural gas.
The petrochemical industry is fundamental to our contemporary world. It supplies many of the raw materials that we rely on: plastics, medicines, lubricants, synthetic rubbers, and synthetic fibers. The petrochemical industry relies heavily on various thermal processes and heat-controlled methods to produce its vital materials. Astec components used in the petrochemical industry include heaters, controls, steam generators, and heat recovery systems.
