Abstract
A method of recovering an extraction aid from distillers corn oil, by directing stillage containing distillers oil and an extraction aid to a centrifugal separator, recovering a light phase from the centrifugal separator, the light phase containing at least a portion of the distillers oil and at least a portion of the extraction aid, cooling the light phase and causing a precipitate to form, and recovering a precipitate from the cooled light phase containing at least a portion of the extraction aid. A method of recovering distillers oil.
Claims32
A method of recovering an extraction aid from a stream containing oil and an extraction aid, including the steps of:
- directing a stream containing oil and an extraction aid to a separator;
- recovering a light phase from the separator, the light phase containing at least a portion of the oil and at least a portion of the extraction aid;
- cooling the light phase and causing a precipitate to form;
- and
- recovering the precipitate from the cooled light phase.
A method of recovering an extraction aid from distillers oil, including the steps of:
- directing stillage containing oil and an extraction aid to a separator
- recovering a light phase from the separator, the light phase containing at least a portion of the oil and at least a portion of the extraction aid.
- cooling the light phase and causing a precipitate to form
- recovering the precipitate from the cooled light phase containing at least a portion of the extraction aid.
A method of recovering an extraction aid from distillers oil, including the steps of:
- directing whole stillage to a first separator
- separating the whole stillage into wet cake and thin stillage
- directing the thin stillage to a second separator
- separating the thin stillage into a light phase containing oil and an extraction aid and heavy phase
- cooling the light phase and causing a precipitate to form and
- recovering the precipitate
A method of producing a distillers oil low in impurities, including the steps of:
- directing stillage containing oil to a separator,
- separating the stillage into a light phase and a heavy phase,
- cooling the light phase and causing a precipitate to form and
- recovering an oil from the light phase.
A distillers oil with one or more of the following:
- phosphorous content of less than 10 ppm, a total content of sodium, potassium, magnesium, and potassium of less than 10 ppm, or combinations thereof.
