Auburn University selects PureVision technology

The Auburn University Center for Bioenergy and Bioproducts is acquiring a rapid biomass fractionation unit developed by Colorado-based PureVision Technology Inc. to use in its research on biochemical and thermochemical conversion processes. PureVision's continuous process employs a countercurrent extraction technique that removes and recovers hemicellulose and lignin fractions in two liquid streams, leaving a solid fraction containing a relatively pure cellulose or fiber. PureVision expects its continuous pilot plant in Fort Lupton, Colo., to be operational in December.
