Abstract:
A coalescence media for separation of water-hydrocarbon emulsions, the coalescence media comprising an emulsion-contacting sheet formed as a single dry layer from a wet-laid process using a homogenously distributed, wet-laid furnish of (a) a mixture of fibrous components of (a1) at least one type of a first group of cellulose and/or cellulose-based fibers, and (a2) at least one type of a second group of fibers selected from the group consisting of fibrillated fibers and glass microfibers, and (b) at least one non-fibrous component selected from the group consisting of (b1) a dry strength additive, and (b2) a wet strength additive. The fibrous components of the coalescence media constitute at least about 70% of the coalescence media, and includes a pore structure sufficient to coalesce water droplets having a droplet size of
