Abstract:
1. Separation media for separating water from a water and hydrocarbon emulsion comprising: a fibrous nonwoven coalescence layer for receiving the water and hydrocarbon emulsion, the coalescence layer being formed of a mixture comprised of glass staple fibers and fibrillated cellulose fibers in an amount sufficient to coalesce the water present in the emulsion to achieve coalesced water droplets having a size of 1 mm or greater as a discontinuous phase within a continuous hydrocarbon phase; and a fibrous nonwoven drop retention layer downstream of the coalescence layer having at least 65 wt. % of natural fibers selected from the group consisting of cellulosic fibers, cotton fibers, wool fibers, silk fibers and rayon fibers, wherein the fibrous drop retention layer exhibits a high BET surface area as measured by water vapor adsorption of at least 90 m
