Polymers in Petroleum Refinery
The chemical gas polymerization process of the UOP operates on olefin-containing gases. In both thermal and catalytic polymerization processes, the feedstock is usually pre-treated to remove sulfur and nitrogen compounds. This method converts propylene and butylene to high-octane fuel or petrochemical polymers. Polymerization may be a method in which a substance of low molecular weight is transformed into one of the same composition but of higher molecular weight, maintaining the atomic arrangement present in the basic molecule. The stability of petroleum is dependent upon the molecular relationships of asphaltene and organic compound constituents and also the balance with the other constituents of petroleum. The asphaltene constituents are the highest molecular weight heaviest and most polar compounds in crude oil. During crude purification, the asphaltene compounds are non-distillable and remain in the residual fuels as the distillable fractions are removed.
