Continuous System and Process for Treating a Low-Water Biomass Stream with Liquefied-Gas Solvent to Separate and Recover Organic Products

摘要

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.
