Abstract
The present invention relates to systems, articles, and methods for removing water from hydrocarbon fluids. In an embodiment, the invention includes a water/fuel separation system including a filter housing and a filter element disposed within the filter housing. The filter element can include a separation article including a porous polymer layer having and a porous substrate comprising a hydrophobic surface. In an embodiment, the invention includes a filter element for separating emulsified water from a hydrocarbon fluid. In an embodiment, the invention includes a method for filtering water out of a hydrocarbon fluid including passing a hydrocarbon fluid through a separation article including a polymer layer comprising polytetrafluoroethylene; and a porous substrate comprising a hydrophobic surface, the polymer layer disposed on the porous substrate.
