  • Coalescer for hydrocarbons containing surfactant
    Patent number: 6422396
    Abstract: A coalescer filter element for the separation of water from hydrocarbon fluids, such as kerosene, jet fuel, diesel fuel, and gasoline under surfactant conditions such as thermal stability additive and dispersant. Coalescer fibrous material has hydrophobic properties which resist surfactant coating of the fibers thereby allowing breakdown of water emulsion in the hydrocarbon fluids. The coalescer has a negative media density gradient in the liquid flow direction.

  • Method and means for dewatering lubricating oils
    Patent number: 4892667
    Abstract: A process for removing by coalescence condensation water from large quantities of lubricating oil of a steam driven turbine a significant portion of which water is in the form of an oil/water emulsion. The process is capable of reducing the free and emulsified water content of lubricating oil having a viscosity rating of 150 ssu at 100.degree. F. from 5000 ppm to 25 ppm in a single pass through the unit at a flow rate of 100 gallons per minute with most of the water in the oil as received by the equipment being in emulsion.
