Lube Oils

The surfactant packages used for lube oil additives are made by sulfonation of heavy alkylates and/or natural petroleum fractions. This can be done either with oleum or by air-SO3 sulfonation. Because of the disposal problems of spent sulfuric acid, the oleum process is being replaced by air SO3 sulfonation.

The global lube and fuel oil additives market is dominated by four companies: Lubrizol (35%), Exxon-Shell (31%), Ethyl (19%), and Chevron (12%). How has Chemithon done in this market? Lubrizol sulfonates 100% with Chemithon equipment. Ethyl sulfonates 100% with Chemithon Equipment. Chemithon has supplied over 66% of the Chevron sulfonation capacity. Of the majors, only Exxon-Shell does not have a new Chemithon sulfonation unit. Chemithon has at least 62% of the market for heavy alkylate sulfonation plants.

Because the product from our units is vastly superior (higher conversion, lower color and sulfuric acid content) than products from competitive equipment, we are the market leader. All new heavy alkylate sulfonation plants use Chemithon sulfonation technology.
