Hybase® detergents and fire-side corrosion inhibitors

The Hybase® 投资组合 offers a range of high TBN overbased detergents and fire-side corrosion inhibitors.

Overbased detergents are additives designed to clean the metal surfaces within a fired engine and prevent the build-up of deposits. The insoluble by-products of the combustion process are removed by the detergents in the lubricants. Detergents find extensive use in marine, passenger car motor oil and heavy duty diesel applications. In addition to cleaning the metal surfaces within a fired engine, overbased detergents also help neutralize acidic combustion by-products to prevent corrosion within the engine. For neutral TBN overbased detergents, see our Lobase® 投资组合.

Fire-side corrosion inhibitors are additives that are designed to prevent corrosion from combustion products resulting from the burning of fuels containing sulfur, vandium and other heavy metals. These products are primarily used in heavy fuel-fired turbines for electrical power generation.
