Abstract
A method of extracting oil from a byproduct stream of a bio-based ethanol production process and a organic composition resulting from the method is provided. The method includes applying an oil concentrator to a byproduct stream, mixing the oil concentrator with the byproduct stream, and separating the oil from the byproduct stream. An organic composition comprising oil derived from a byproduct stream of a bio-based ethanol production process and an oil concentrator is also provided.
Claims16
A method of extracting oil from a byproduct stream of a bio-based ethanol production process, comprising:
- mixing an ethoxylated sorbitan ester with the byproduct stream;
- centrifuging the mixture of the ethoxylated sorbitan ester and the byproduct stream;
- and
- separating the oil from the mixture.
A method of extracting oil from a liquid stillage byproduct of a bio-based ethanol production process, comprising:
- evaporating water from the liquid stillage to produce a syrup;
- processing the syrup to a temperature between 100° F. and 212° F. and a pH between 3 and 7;
- mixing a polyoxyethylene (20) sorbitan ester with the syrup;
- centrifuging the mixture;
- and
- separating the oil from the mixture.
