Sub-Product

Generic naphtha product when the exact naphtha type is not known; its selection should preferably be avoided and a more defined type of naphtha product selected for modeling sites.

Naphtha is a name given to several mixtures of liquid hydrocarbons that are extremely volatile and flammable. Each such mixture is obtained during the distillation of Petroleum or Coal Tar, and occasionally by the distillation of Wood. Accordingly, it is known by different names, such as Petroleum Naphtha, Coal-Tar Naphtha, or Wood Naphtha. Naphtha is used primarily as feedstock for producing a high-octane Gasoline component via the catalytic reforming process. It is also used in the petrochemical industry for producing Olefins in steam crackers and in the chemical industry for solvent (cleaning) applications.
