Abstract:
A vortex tube is disclosed. A vortex tube is a slender tube with a diaphragm closing one end of the tube with a discharge hole in the center of the diaphragm with tangential inlet nozzles. The vortex tube separates an inlet gas stream into two compartments. The present invention relates to an optional geometry of the vortex tube for use with compressed natural gas.

Claim (Index 1):
A method for a non-freeze enhancement in a vortex tube assembly, said non-freeze enhanced vortex tube assembly includes a heat exchanger having an uncontrolled opening with a diameter (d) in the heat exchanger's inner passage and a vortex tube comprising a slender tube with a diameter (D), the uncontrolled opening diameter (d) is no greater than 0.6 times the slender tube diameter (D), a diaphragm having a hole in the center thereof and closing one end of the vortex tube. one or more tangential nozzles piercing the slender tube just inside the diaphragm and an outlet opening on the other end of the vortex tube, the method comprises ways of connecting the non-freeze enhanced vortex tube as follows:\n a. attaching the heat exchanger to an outward side of a vortex tube's diaphragm; b. connecting a vortex tube's diaphragm for discharging a cold fraction flow with the heat exchanger's inlet opening and then connecting the inlet opening through the heat exchanger's inner passage with the heat exchanger's outlet opening to discharge gas flow from the non-freeze enhanced vortex tube assembly; and c. connecting a vortex tube outlet opening at the far end of the vortex tube with another inlet opening of the heat exchanger, thus providing for the hot flow to flow over the surfaces on the inside of the heat exchanger and then leave or exit the heat exchanger through an uncontrolled opening in the heat exchanger's inner passage to mix with the cold fraction exiting the vortex tube.
