Abstract
A cyclone separator for a superfluid extraction apparatus comprising a cyclone inlet weldment comprising a cyclone, a collector tube connected to the cyclone inlet weldment, and a needle support manifold extending from the cyclone inlet weldment comprising a fluid flow directing needle, the needle having a relief cut to control fluid flow into the separator. A supercritical fluid pump is described having a piston assembly with a hydraulic cylinder and a cylindrical integral check valve piston with at least two circumferential seals to seal the piston against the barrel insert and a check assembly extending axially through one end of the integral check valve piston and between the at least two circumferential seals to relieve excess pressure.
Claims20
A cyclone separator comprising:
- a cyclone inlet weldment comprising a cyclone and a needle inlet port;
- a collector tube weldment connected to the cyclone inlet weldment;
- a needle support manifold connected to the cyclone inlet weldment and further connected to a fluid flow line;
- and
- a fluid flow directing needle extending through the needle support manifold to the needle inlet port, the fluid flow directing needle having a relief cut creating a fluid flow channel between the needle and the needle inlet port to control fluid flow into the separator.
A system for superfluid extraction of an extractant from a solid material comprising:
- a pump for pumping supercritical fluid at a pressure to maintain the supercritical fluid in a gas and liquid state;
- an extraction vessel;
- and
- a superfluid flow path comprising:
- a cyclone separator comprising a cyclone inlet weldment comprising a cyclone, a needle inlet port, and a collector tube connected to the cyclone inlet weldment;
- a needle support manifold connected to the cyclone inlet weldment and further connected to a fluid flow line;
- and
- a fluid flow directing needle extending through the needle support manifold to the needle inlet port, the fluid flow directing needle having a relief cut creating a fluid flow channel between the needle and the needle inlet port to control fluid flow into the cyclone separator.
