Traditional CO2 extraction system
The gas booster extracts the steam or gas of saturated soluble substances (such as marijuana, hops, coffee beans, etc.) to extract the required products. In the closed-loop system, after the separated oil is separated and directly flows into the inlet of the booster, the steam leaves the separator. From here, they are pumped and compressed back into the extraction vessel to achieve the higher pressure required for extraction.
In this system, carbon dioxide is continuously compressed to high pressure in the extractor vessel and depressurized to steam (to extract oil) in the separator. Then the steam goes into a pump, where it repeats the process.
Gas boosters are useful when the cylinder pressures are much lower than the autoclave ratedpressures. In such case the booster takes gas at lower pressure from cylinder & compresses thesame to deliver at higher pressures. They are generally pneumatically operated. Special gasbooster pumps are available for liquid CO used in supercritical fluid extraction system. The 2booster systems are supplied with air filter regulator, pressure relief valves, inlet-outlet pressuregauges, valves & flexible hose pipe.
