Olefins includes ethene, propene, butenes and butadiene. Ethylene and propylene are important sources of industrial chemicals and plastics products. Butadiene is used in making synthetic rubber. Petrochemicals are produced using extreme temperatures (over 1500 ⁰F) and pressures (over 1000 psi). This process requires large amounts of energy and sophisticated engineering. Petrochemical plants utilize many of the same tools as refineries to purify the chemicals for distribution to chemical manufacturers.
Most common aromatic compounds are derivatives of benzene, an aromatic hydrocarbon common in petroleum and its distillates. They are extracted from complex mixtures obtained by the refining of oil, or by distillation of coal tar. They are used to produce a range of popular chemicals and polymers, including styrene, phenol, aniline, polyester and nylon. Aromatics are produced by catalytic reforming of naphtha. Sundyne integrally geared centrifugal pumps and compressors are widely utilized for aromatics processing.
Process engineers produce methanol by hydrogenation of carbon monoxide, natural gas, coal, biomass and recycled carbon dioxide in petrochemical plants. Methanol is used as a feedstock to commodity chemicals, including formaldehyde, acetic acid, methyl tert-butyl ether, dehydration, de-icing and it is also a fuel additive.
