DMT to Supply Desulfurization Process to California AD Facility
by Erin Voegele (Ethanol Producer Magazine) DMT Clear Gas Solutions recently announced that Calgren Dairy Fuels LLC is going to install DMT’s desulfurization technology, Sulfurex BR. The anaerobic digestion (AD) facility is located adjacent to Calgren Renewable Fuels LLC, a 55 MMgy ethanol plant located in Pixley, California. The AD facility provides heat and power to the ethanol plant.
