NATGI's hydrocarbon recovery technology is based on an oleophilic amine-coated ceramic chip that separates suspended and dissolved hydrocarbons from aqueous solutions. The hydrophobic amine coating makes each granule more electrochemically attractive to hydrocarbons in an unstable emulsion. The technology utilizes a Separator/Filter/Coalescer Olefiltration System (SFC System), a pressure-sensitive filtering bed that is regenerated by automatic back-flushing. Recovered hydrocarbons are coalesced and removed by gravity separation. The SFC System was demonstrated at the Petroleum Products Corporation site in Pembroke Park, Florida, in June of 1994. Artificial feeds were formulated by mixing waste oil from the site with 10W-30 motor oil or kerosene, and water to create oil/water emulsions having a treatable viscosity. Due to operational difficulties, only one complete run was accomplished. The technology was evaluated by pooling data from specific runs. Combined data from the runs with similar feed streams (Runs 1,2,3, and 5) showed a 95 % reduction in TRPH concentration. A 65 % reduction in TRPH was obtained for the entire Run 4; a 97 % reduction was measured for Run 4 prior to breakthrough.
