Abstract:
1. An apparatus for extracting and recovering components from a biomass feedstock with pressurized low polarity water, comprising: two or more reaction columns, each column separately communicating with: (i) a supply of heated water, (ii) a supply of heated pressurized water, and (iii) a supply of cooled pressurized water, each column having an outlet for egressing a liquids product flow; a pump for pressurizing each of said reaction columns; a plurality of valves cooperating with each of said reaction columns and said pumps to: (iv) pressurize each of said reaction columns to a selected pressure, (v) to maintain the selected pressure in each of said reaction columns for a selected time period, and (vi) to release pressure in each of said pressurized reaction columns; a collection vessel for receiving the liquids product flow from each of said columns during a period of time when each of said columns is pressurized; and additionally comprising a vessel for receiving a waste water flow egressing from each of said reaction columns after each of said columns has been de-pressurized.
