Abstract
The invention discloses an apparatus for filtration of water from hydrocarbons comprised of a fresh-feed inlet, a first dead end filter, that is hydrophobic, a second sweeping-flow filter, that is hydrophobic, a common housing containing both the first and second filters, a system for the recirculation of the retentate, a chamber for water settling, and an outlet for clean fuel permeate. This invention takes advantage of the properties of the functional groups of a surfactant, by using the surfactant to allow a hydrophobic medium to attract water, attach the water molecules to the hydrophobic medium, and then allow for agglomeration of the water molecules, which finally become large enough to detach and be swept away by the sweeping-flow. This invention can thus be used to remove high concentrations of water, up to 5%, in hydrocarbons, while allowing a high flow rate by preventing blockage of the final filter by water.
