Multiple-stream pressurized low polarity water extraction apparatus, system, and methods of use

An apparatus for extracting and recovering components from a biomass feedstock with pressurized low polarity water, comprising:

• four or more reaction columns, each column separately communicating with:
• (i) a supply of heated water, (ii) a first supply of heated pressurized water, (iii) a second supply of heated pressurized water, and (iv) a supply of cooled pressurized water, each column having an outlet for egressing a liquids product flow, configured such that one of the reaction columns optionally receives a flow of heated pressurized water from the first supply of heated pressurized water while a second of the reaction columns is receiving a flow of heated pressurized water from the second supply of heated pressurized water;
• a first pump pressurizing a first portion of the supply of heated water to provide said first supply of heated pressurized water downstream of the first pump;
• a second pump pressurizing a second portion of the supply of heated water to provide said second supply of heated pressurized water downstream of the second pump;
• a first plurality of valves cooperating with each of said reaction columns and (i) the supply of heated water, (ii) the first supply of heated pressurized water, (iii) the second supply of heated pressurized water, and (iv) the supply of cooled pressurized water, for controlling a flow from each of said supplies of hot water, heated pressurized water and cooled pressurized water into each of said reaction columns;
• a second plurality of valves cooperating with each of said reaction columns and (i) the supply of heated water, (ii) the first supply of heated pressurized water, (iii) the second supply of heated pressurized water, and (iv) the supply of cooled pressurized water, for controlling a flow of each of said supplies of hot water, heated pressurized water and cooled pressurized water out of each of said reaction columns;
• and
• a collection vessel for receiving a liquids product flow from each of said columns during a period of time when at least one of said columns is receiving a flow from the first supply of pressurized heated water or from the second supply of pressurized heated water.
