  • Biomass pretreatment
    Patent number: 9334545
    Abstract: A system for pre-treating biomass for the production of ethanol is provided. The system supplies biomass to a steaming bin, wherein the biomass is mixed with water, and inputting the steamed biomass to a first pretreatment reactor, wherein the steamed biomass comprises liquids and solids. The system removes a bulk of liquids from the solids and feeding the solids into a second pretreatment reactor. The system applies a pressure drop to the solids in the second pretreatment reactor, wherein the pressure drop opens up a structure of the solids, and sending the solids to a fermentation process for ethanol processing.
    Type: Grant
    Filed: November 12, 2013
    Date of Patent: May 10, 2016
    Assignee: Andritz Inc.
    Inventors: William F. McDonald, David Charles Carlson, Wiley D. Bradford
