High Yield, High Efficiency Bio-Refining

Processing of vegetable oils is complicated by the need to remove free fatty acids. Washing with caustic is a viable process but is inefficient because fatty acids and caustic form soaps which cause emulsions. These emulsions cause a yield loss of 1-1.5% or 160-240 Million lb/yr of soybean oil alone. The purpose of this project is to improve yields in vegetable oil processing with a novel non-dispersive contactor that extracts free fatty acids from vegetable oils and biodiesel without causing emulsions.
