Ethanol - Corn Oil

COSS™ (Corn Oil Separation System)

A typical dry mill corn ethanol facility generates a DDGs product containing approximately 11-12% by weight of Corn Oil. A 100 MGY ethanol facility typically has over 10 million gallons of Corn Oil contained within the DDGs product. The Corn Oil is worth 3-4 times that of the DDGs. Not only is the oil worth more, depending on the DDGs handling and customer base, removal of the oil can be desirable to improve the DDGs processing properties and feed value.

Approximately 25-30% of the total available Corn Oil within the DDGs of a dry mill ethanol plant can cost effectively separate the Corn Oil from the thin stillage after it has been concentrated though the evaporation process.

SRS has developed the COSS (Corn Oil Separation System) turnkey system through a specially designed separation module that effectively allows SRS to break the Corn Oil emulsion and recovery of over 85% of the oil available within the concentrated thin stillage. The system returns the stillage back to the evaporator system for further processing.

The separated Corn Oil is further refined, tested and marketed by SRS to ensure maximum market value. The COSS is reliable, fast and results can verified with our pilot testing system.
