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 re-move these contaminants from the compositions.
