  • METHOD OF REMOVING A CONTAMINANT FROM A CONTAMINANT-CONTAINING BIOLOGICAL COMPOSITION USEFUL AS A BIOFUEL FEEDSTOCK
    Publication number: 20160340605
    Abstract: Biological compositions containing animal fats and plant oils desirably are free of contaminants prior to processing into a biofuel. Disclosed herein is a method of removing such contaminants from these compositions to make that processing more efficient. The method employs a unique arrangement of mixers and centrifuges along with acidic solutions and recycle streams to remove these contaminants from the compositions.
