Methyl Ester Purification (Biodiesel)

Sergeant Bluff, Iowa

Koch Modular designed and supplied a commercial biodiesel purification unit to a Midwest customer in 2003. The objective of this unit was to purify methyl esters by vacuum distillation from a crude biodiesel stream which includes impurities such as water, methanol, glycerin, mono-glycerides, di-glycerides, tri-glycerides and other high boilers. This plant has been successfully operating for over 7 years.
