Abstract:
A coalescence media for separation of water-hydrocarbon emulsions comprises an emulsion-contacting sheet formed of: (a) at least one component of the group consisting of natural fibers, cellulose fibers, natural-based fibers, and cellulose-based fibers, at least one component of the group consisting of high-surface-area fibrillated fibers, surface-area-enhancing synthetic material, glass microfibers, and nanoceramic functionalized fibers; and (c) at least one component of the group consisting of a dry strength additive, and a wet strength additive, wherein the fibrous components of the media constitute at least about 70% of the media. In preferred embodiments, the coalescence media comprises kraft fibers, fibrillated lyocell fibers, glass microfibers or nanoceramic functionalized fibers, a wet strength additive, and a dry strength additive. Preferably, the coalescence media is formed as a single, self-supporting layer from a wet-laid process using a homogenously distributed, wet-laid furnish. It may also be formed as a multi-layer structure.
