  • Patent number: 10751641
    Abstract: A portable supercritical fluid extraction apparatus, comprising: (i) a pressure vessel for generating a supercritical fluid therein; (ii) a liquid solvent supply tank; (iii) a means for interconnecting said pressure vessel and said liquid solvent supply tank at a predetermined angle for delivery therethrough of a liquid solvent from the liquid storage tank to the pressure vessel; and (iv) a heating component for heating contents of the pressure vessel to produce a supercritical fluid therein. The apparatus may additionally comprise a sample in fluid communication with the pressure vessel, and a receiving vessel in fluid communication with the pressure vessel. The pressure vessel may have a heating means for heating fluid contents therein, for example a heating wrap, a heating block, or a heating jacket.

  • Patent number: 7021900
    Abstract: A kinetic pump and method of pumping a liquid comprising providing an acceleration tube for the acceleration of a liquid contained therein by an introduced high-pressure vapor or gas, receiving the liquid from the acceleration tube with a compressed-air surge tank, admitting the liquid from the acceleration tube into the compressed-air surge tank via a check valve, draining the liquid from the compressed-air surge tank from an outlet, and adding additional liquid to the acceleration tube via an inlet, wherein during each first half cycle of the method, the vapor or gas forces the liquid to accelerate in the acceleration tube, whereby a portion of the liquid is forced into the compressed-air surge tank, and wherein during each second half cycle of the pump, the vapor or gas is substantially removed from the acceleration tube and the liquid flows back to its original location and the additional liquid is added to the liquid.
