Simplot Company generates 2 million pounds of oil each year. Simplot would like to condition the oil and convert it to biodiesel, which would then be returned to Simplot to offset the diesel used in the transportation fleet. • The waste oil generated in production lines forms two waste streams. Our team has determined that one of these streams is already suitable for conversion to biodiesel. • The secondary waste stream, DAF (Dissolved Air Floatation) oil, is being wasted to cattle feed. Our goal is to take both elements of DAF oil (MOP and WESP) and convert them to the proper specs for the production of biodiesel. • In order to condition the oil, the team will design a system to remove free fatty acids, water, particulates, and other carbon impurities from the used oil to a specification defined by the biodiesel manufacturer. • <4% FFA • <.1% Water by weight • <50-100 micron particulate size Integrated Solution Recommended Treatment Process Design Challenges Accomplishments Further lab analysis of the WESP and MOP oils will allow us to determine a treatment plan. Hazardous chemicals near food processing plant. Effective cost analysis. Bench-top model. Team French Fry Fuel has performed numerous tests on the mainstream oil. We determined that it is suitable for conversion to biodiesel. Senior Design Snap Shot Day November 30, 2007
