Abstract:
A method of processing thin stillage in an ethanol refining operation is provided. The method comprises treating thin stillage upstream of a concentration or evaporation step with an aid comprising a sorbitan ester of a fatty acid, an ethoxylated sorbitan ester of a fatty acid, or a combination thereof, thereby forming treated thin stillage. The aid may include at least one of sorbitan monooleate, polyoxyethylene sorbitan monostearate, and polyoxyethylene sorbitan monolaurate.
