20120118517 | SOLID/FLUID SEPARATION DEVICE AND METHOD FOR TREATING BIOMASS INCLUDING SOLID/FLUID SEPARATION - A solid/fluid separation module and pretreatment apparatus and method enables pretreatment of biomass at high temperature and pressure with the ability to vary residence and processing times. | 05-17-2012 |
20130025798 | SOLID AND LIQUID SEPARATION PROCESS - A process for separation of solid and liquid components in a distillation whole stillage utilizing airless spray drying is disclosed, which is more efficient and economical than conventional processes. In the process, distillation whole stillage resulting from distillation of fermented biomass is first subjected to an evaporation step for separating the whole stillage into a condensate and a concentrate including water, dissolved solids and suspended solids. The concentrate is then subjected to airless steam spray drying for converting the concentrate into dried solids, steam and vapors. All steam and vapors resulting from the airless steam spray drying step are then redirected as energy source to a processing step upstream of the airless spray drying step. At least some of the steam generated in the airless spray drying step is airless steam. | 01-31-2013 |
20130175467 | DE ICING FORMULATION UTILIZING CO-PRODUCTS FROM LIGNOCELLULOSE TO BIO FUEL PROCESS - The use of a side stream and residue from the lignocellulose to ethanol process for use in preventing the formation of ice and in melting ice and snow on roadways. The future lignocellulose to ethanol industry will provide a significant proportion of these streams that provide an organic solution that when added to chloride salts of calcium, magnesium and sodium provides an improved environmentally friendly road deicing product with reduced corrosiveness and increased friction. A deicer composition of calcium chloride aqueous solution containing 25-38% by weight calcium chloride mixed up to 50% by volume of hemicellulose hydrolysis side stream can reduce the corrosivity of calcium chloride to 70% less that of a sodium chloride solution. | 07-11-2013 |
20130264264 | TWIN SCREW EXTRUDER PRESS FOR SOLID/FLUID SEPARATION - Disclosed is a solid/liquid separation apparatus including an extruder press combined with a solid/fluid separation module for separating fluid from a mass of solids compressed by the extruder at elevated pressures. The extruder includes two or more extruder screws with flighting intercalated at least along a part of the extruder barrel. The separation module forms a continuation of the barrel, receives the pressurized mass and at least a portion of the twin screws, and includes a filter pack consisting of a filter plate and a backer plate. The filter plate has a throughgoing filter slot extending away from a core opening and into the filter plate for directing fluid away from the core opening. The backer plate has a core opening shaped and sized equal to the barrel and defines a passage for guiding fluid collected in the filter slot to an exterior of the filter pack. | 10-10-2013 |
20140110324 | SOLID/FLUID SEPARATION DEVICE AND METHOD FOR TREATING BIOMASS INCLUDING SOLID/FLUID SEPARATION - A solid/fluid separation module and pretreatment apparatus and method enables pretreatment of biomass at high temperature and pressure with the ability to vary residence and processing times. | 04-24-2014 |
