Weatherspoon, Advisor Dr. Tom Hess,
The J.R. 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.
Background
Conditioning used frying oil for conversion to 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
Problem Statement
Team French Fry Fuel has performed numerous tests on the mainstream oil. We determined that it is suitable for conversion
to biodiesel.
