Abstract: An ion exchange column and a method of using the same are disclosed. The ion exchange column includes first interconnected chambers supporting a first portion of an ion exchange resin, second interconnected chambers supporting a second portion of the ion exchange resin, and a housing or casing enclosing the first and second interconnected chambers and the first and second ion exchange resin portions. The second chambers are physically isolated and/or separated from the first chambers. The ion exchange column is configured to cause a fluid passing through the first or second interconnected chambers to travel along a path that is longer than a height of the interconnected chambers. The present column and method improve efficiencies of fluid treatment and resin regeneration relative to a conventional dual-column design, and increase residence time between the resin and the fluid or regenerant relative to an otherwise identical single-column design.

Abstract: A process for the continuous purification of biodiesel (fatty acid alkyl esters (FAAE)) is described using a powdered, granulated or extruded adsorbent. The adsorbent is contained in a column system and is regenerated for reuse multiple times. The crude biodiesel 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, free glycerin, sterol glucosides and many of the other impurities that reduce the stability of biodiesel. The resulting finished biodiesel exiting the column(s) is ready for the methanol recovery process. Once the adsorbent no longer removes the desired amount of impurities, it is regenerated for reuse. The solvent used for the regeneration process is reclaimed and reused by recycling it back to the transesterification reaction.
