Dual phase extraction apparatus

A dual phase recirculating extraction apparatus, comprising:

• an extraction vessel having first and second extraction vessel openings, wherein each extraction vessel opening can function either as an ingress or an egress, the extraction vessel configured to receive a process fluid through the ingress, allow the process fluid to come into contact with a source material within the extraction vessel to form a mixture, and permit the mixture to exit the extraction vessel through the egress;
• a first filter adapted to retain the source material while also allowing the process fluid or the mixture to pass through the first extraction vessel opening;
• a second filter adapted to retain the source material while also allowing the process fluid or the mixture to pass through the second extraction vessel opening;
• a separation chamber;
• a circulation conduit configured to direct the process fluid into the extraction vessel through a predetermined ingress selected from the first and second extraction vessel openings, direct flow of the mixture from the extraction vessel to the separation chamber, allow a portion of the extracted material to separate from the mixture within the separation chamber, and thereafter allow recirculation of the process fluid to the extraction vessel through a next predetermined ingress selected from the first and second extraction vessel openings;
• a gas pump connected to the circulation conduit and configured to receive the process fluid in a gaseous state and compress the process fluid;
• a liquid pump connected to the circulation conduit and configured to receive the process fluid in a liquid state and compress the process fluid;
• an extraction temperature regulator including an extraction heating/cooling source, an extraction temperature regulation fluid, an extraction temperature regulation line, an extraction temperature set heat exchanger configured to selectively adjust the temperature of the process fluid prior to entering the extraction vessel, and wherein the extraction temperature regulator is configured to allow recirculation of the temperature regulation fluid;
• and
• a recirculation thermal manager including a recirculation cooling source, a recirculation thermal management fluid, a recirculation thermal management line, and first and second recirculation heat exchangers, the recirculation thermal manager configured to allow recirculation of the recirculation thermal management fluid and to regulate the temperature of the process fluid.
