NOVELTY - The coalescing media are configured for capturing droplets of the dispersed phase and coalescingly growing the droplets into larger drops which grow to a sufficient size and are released from the media. The media comprise a polymeric base material having a heterogeneous surface comprising asperities. The media are configured for capturing droplets of the dispersed liquid phase. A layer of air is trapped at the heterogeneous surface and tips of the asperities extend through the trapped layer and contact the droplets.    USE - Coalescing media are used in coalescing elements of coalescing systems for coalescing mixture of two immiscible phases, namely continuous phase and dispersed liquid phase, in removal of dispersed phase comprising hydrocarbon liquid and/or water dispersed in continuous gas phase (all claimed). Uses include but are not limited to protection of environment in open crankcase ventilation applications, protection of turbochargers in closed crankcase ventilation applications, fuel-water separation, and oil-water separation. The hydrocarbon liquid includes hydrocarbon fuel, biodiesel fuel, or lubricating, hydraulic or transmission oil.    ADVANTAGE - The coalescing media exhibit desirable properties with respect to drainage of the dispersed phase, reduced pressure drop, and increased removal of the dispersed phase.    DETAILED DESCRIPTION - The coalescing media are configured for capturing droplets of the dispersed phase and coalescingly growing the droplets into larger drops which grow to a sufficient size and are released from the media. The media comprise a polymeric base material having a heterogeneous surface comprising asperities. A preponderance of the heterogeneous surface is non-wetting with respect to the dispersed liquid phase. The media are configured for capturing droplets of the dispersed liquid phase. A layer of air is trapped at the heterogeneous surface and tips of the asperities extend through the trapped layer and contact the droplets. INDEPENDENT CLAIMS are included for the following:    (1) manufacture of coalescing media;    (2) coalescing element; and    (3) method of removing dispersed phase comprising hydrocarbon liquid and/or water dispersed in a continuous gas phase.    DESCRIPTION OF DRAWING(S) - The drawing shows a conceptual view of an air-jacketed coalescer media.
