Extraction systems and methods

Abstract

System and methods are disclosed with a holding tank to receive liquid and cryogenically frozen biomass; a cavitator to generate shock waves and pressure variations, wherein the shock waves and pressure variations are to the biomass and the liquid to separate oil from the biomass; a sensor to determine when oil concentration exceeds a threshold; and a valve to transfer the oil and liquid to an oil tank when the threshold is met.

         7 . The method of  claim 1 , comprising converting a post oil extraction biomass into a bioplastic or a biocomposite material. 
     
     
         8 . The method of  claim 1 , comprising converting a post oil extraction biomass into a building material. 
     
     
         9 . The method of  claim 1 , wherein the liquid comprises water or a solvent. 
     
     
         10 . The method of  claim 1 , wherein after extraction, further comprising:
 reducing the biomass into small fragments and extracting oil therefrom with post-extraction biomass;   processing the post-extraction biomass using steam explosion;   treating the post-extraction biomass by dilute acid hydrolysis;   treating unreacted lignocellulostic component of acid hydrolyzed crop post-extraction biomass by alkaline delignification; and   generating bio-plastic from the post-extraction biomass.   
     
     
         11 . A system to process a biomass, comprising:
 a holding tank to receive liquid and cryogenically frozen biomass;   a cavitator to generate shock waves and pressure variations, wherein the shock waves and pressure variations are to the biomass and the liquid to separate oil from the biomass;   a sensor to determine when oil concentration exceeds a threshold; and   a valve to transfer the oil and liquid to an oil tank when the threshold is met.   
     
     
         12 . The system of  claim 11 , comprising a chemical processor to extract oil from the crop and thereafter using the crop as a bio-material. 
     
     
         13 . The system of  claim 11 , wherein the oil comprises tetrahydrocannabinol (THC) or cannabidiol (CBD) from the liquid. 
     
     
         14 . The system of  claim 11 , comprising a temperature sensor coupled to the liquid, wherein cryogen is applied to the liquid. 
     
     
         15 . The system of  claim 11 , comprising a sensor to detect oil concentration in the liquid. 
     
     
         16 . The system of  claim 15 , wherein the oil is removed once the oil concentration exceeds a threshold, wherein the liquid is water, comprising a boiler to boil off water, a centrifuge, or a nano filter to remove oil from the water. 
     
     
         17 . The system of  claim 11 , comprising a second oil extraction stage for tetrahydrocannabinol (THC) or cannabidiol (CBD) using ethanol and cryogenic cooling with LN2 or CO2.
