  • Patent number: 9920091
    Abstract: A method and system for the treatment of a biomass stream to separate organic extracts/biomolecules (such as proteins, lipids and/or carotenoids) from the biomass stream, wherein the water content of the biomass stream is decreased by bringing the biomass stream into contact with a compressed liquefied gas solvent, to create a low-water content biomass stream and introducing the low-water content biomass stream to an extraction apparatus that recovers one or more organic products with little or no measurable solvent residue.
    Type: Grant
    Filed: March 13, 2017
    Date of Patent: March 20, 2018
    Assignee: Green Recovery Technologies, LLC
    Inventors: Joseph N. Caulfield, Kenneth L. Laubsch, Bruce J. Rudin

  • Patent number: 9651304
    Abstract: A pretreatment for use with systems and methods for extracting and separating a bio-molecule, such as a lipid and/or a protein, from a biomass includes the step of contacting the biomass with a drying gas to substantially dewater the biomass to 20% water content by mass or less. Such pretreated biomass, mixed with one or more compressed liquefied gas solvents, may then be introduced into individual filter cells in a rotary pressure filter to separate lipids from proteins.
