Claim Text:
1. A process for removing an immiscible lipophilic liquid from a continuous hydrophilic liquid phase or an immiscible hydrophilic liquid from a continuous lipophilic liquid phase, comprising the steps of: forming a filter containing hydrophobic fibers and hydrophilic fibers; flowing a liquid composition through the filter, where the liquid composition is selected from the group consisting of an immiscible lipophilic liquid in a continuous hydrophilic liquid phase and an immiscible hydrophilic liquid in a continuous lipophilic liquid phase; capturing the immiscible lipophilic liquid or the immiscible hydrophilic liquid; coalescing the captured immiscible lipophilic liquid or immiscible hydrophilic liquid; and removing the coalesced immiscible lipophilic liquid or immiscible hydrophilic liquid from the filter, wherein the hydrophobic fibers comprise one or more polymers selected from the group consisting of polyethylene, polypropylene, nomex, polyester, a halogen-containing polymer, rubber, polyurethane, polycarbonate, and a silicone polymer; and wherein the hydrophilic fibers comprise one or more glasses selected from the group consisting of sodium glass, boron glass, phosphate glass, and B-glass.
