COALESCER FOR HYDROCARBONS CONTAINING STRONG SURFACTANT

摘要

A coalescer filter element for the separation of water from hydrocarbon fluids, such as kerosene, jet fuel, diesel fuel, and gasoline under strong surfactan t conditions such as thermal stability additive, dispersant and detergent. Coalescer fibrous material has hydrophobic properties which resist surfactant coating of the fibers thereby allowing breakdown of water emulsion in the hydrocarbon fluids. The coalesces has a negative media density gradient in the liquid flow direction.
