Artisan’s thin-film technology is ideally suited to purify biodiesel from its chemical by-products downstream of the esterification and/or transesterification reactions. Using Artisan’s biodiesel purification process eliminates the need for a separate glycerin purification process.see url
go Most biodiesel processes require less than 1% free fatty acid (FFA) in the feedstock. The price of these feed materials, generally, vegetable oils, has skyrocketed with increasing demand. Using our Rototherm® technology, Artisan developed an economical one–step process that yields a material with only 1% FFA from inexpensive low–grade feedstocks containing up to 25% FFA with no need for additives. The process also produces high quality fatty acids that can be sold or further esterified to produce biodiesel.see url

The crude glycerin contains inorganic salts, heavies, solvent and water and is considered a hazardous waste as generated from most biodiesel processes. Artisan has developed a cost effective process to purify the glycerin from crude to fuel grade, tech grade, or USP grade, depending on the quality of the feedstock used in the process.
