Dry Wash Resin Ion Exchange Resin as Dry Wash Media

摘要

Ion exchange resin was introduced in the biodiesel industry as a dry-wash media. Now, it is being used for a number of other applications in biodiesel plants, including esterification catalysts, media to improve cold soak filtration test performance and glycerin purification. Ironically, ion exchange resin is increasingly being utilized in water-wash plants to decatonize wash water, and to polish and dry the finished fuel.
