Abstract
The process utilizes the adsorbent column system as a treatment after chemical refining or before physical refining rather than water or filtration, respectively, to remove soaps and other impurities entrained in a crude triacylglycerol. The CDTAG or ORTAG is contacted with an adsorbent packed into a column, or multiple columns in series, for a sufficient amount of time to remove impurities such as, but not limited to, soaps, metals, chlorophyll, and many of the other compounds that reduce the stability of the TAG. The resulting TAG exiting the column(s) is ready for the deodorization process. Once the adsorbent no longer removes the desired amount of impurities, it is regenerated for reuse. Such a continuous regenerable adsorbent refining process substantially reduces the amount of fresh water required and the amount of waste water generated to purify TAG and reduces the amount of solid waste produced.
