ANDRITZ to supply biomass pre-treatment technology
October 24, 2012, Graz, DE – ANDRITZ, through its U.S. subsidiary ANDRITZ Inc., has received an order to supply its advanced continuous biomass pre-treatment technology for the Poet-DSM Advanced Biofuels commercial-scale biofuel facility being built in Emmetsburg, Iowa.
Poet-DSM’s Project Liberty facility, its first commercial-scale second generation cellulosic ethanol plant, will produce 20 million gallons per year by using corn cobs, leaves, husk, and some stalk to produce renewable fuel. Construction is scheduled to be complete by the end of 2013.
ANDRITZ’s advanced steam explosion (SteamEx) technology is a two-stage process, which includes a vertical reactor, interstage washing, and continuous steam explosion technology. The technologies will be employed to help in the pre-treatment of biomass so that it can be converted into low-cost sugars, which will be used in the production of ethanol. These technologies are well-proven in other industrial processes and, through extensive R&D in liquid biofuels, have been optimized by ANDRITZ to satisfy the requirements for Project Liberty.
