A system and method for a chromium recovery process for recovering chromium from byproducts resulting from a tannery process. A system and process for solubilizing chromium contained in the oil byproduct into the remaining water content within the oil and extracting the water from the oil with the chromium sufficiently solubilized in the water such that the chromium content in the oil is sufficiently reduced below hazardous levels.

Recovering chrome from a tannery process

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.

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.
