A gas-liquid separator uses a helical passageway to impart a spiral motion to a fluid passing therethrough. The centrifugal fore generated by the spiraling motion urges the liquid component of the fluid radially outward which forces the gas component radially inward. The gas component is then filtered through a gas-permeable, liquid-impervious membrane and discharged through a central passageway.

1. A method of removing gas from a fluid mixture containing a liquid component and a gas component, comprising:receiving the fluid mixture in a cylindrical chamber; advancing the fluid mixture in a substantially helical path through the chamber such that the liquid component is urged radially outwar
1. A method of removing gas from a fluid mixture containing a liquid component and a gas component, comprising:receiving the fluid mixture in a cylindrical chamber; advancing the fluid mixture in a substantially helical path through the chamber such that the liquid component is urged radially outward while the gas component is urged radially inward; filtering the gas component from the liquid component; and discharging the gas component from the chamber. 2. The method of claim 1, wherein discharging the gas component comprises reducing an air pressure at a gas component outlet.3. The method of claim 1, wherein discharging the gas component comprises exposing the gas component directly to an environment external to the chamber.4. The method of claim 1, wherein receiving the fluid mixture comprises pumping the fluid mixture into the chamber.5. The method of claim 1, wherein receiving the fluid mixture comprises allowing the fluid mixture to flow under its own weight into the chamber.6. The method of claim 1, further comprising sealing the chamber to prevent leakage of the fluid mixture.7. An apparatus for removing gas from a fluid mixture containing a gas component and a liquid component, comprising:a cylindrical housing; an inlet for providing fluid communication with the cylindrical housing; a spiral core mounted on a hollow, perforated spiral core support member and housed within the cylindrical housing; and a membrane layer coaxially adjacent to the hollow, perforated spiral core support member. 8. The apparatus of claim 7, wherein the membrane layer is gas-permeable and liquid-impervious.9. The apparatus of claim 7, wherein the membrane layer is adjacent to an inner surface of the hollow, perforated spiral core support member.10. The apparatus of claim 7, wherein the membrane layer is adjacent to an outer surface of the hollow, perforated spiral core support member.11. The apparatus of claim 7, wherein the membrane layer is supported by a hollow, perforated membrane support member disposed coaxially within the hollow, perforated spiral core support member.12. The apparatus of claim 7, further comprising first and second inner flanges attached to proximal and distal ends, respectively, of the cylindrical housing.13. The apparatus of claim 12, further comprising first and second outer flanges connectable to the first and second inner flanges, respectively.14. The apparatus of claim 13, further comprising an elastomeric annular seal between the first inner flange and the first outer flange and between the second inner flange and the second outer flange.15. The apparatus of claim 14, wherein each of the first and second outer flanges has an annular groove formed therein for receiving the elastomeric seal.16. The apparatus of claim 13, wherein each of the first and second outer flanges has an annular shoulder defining a recess therein for receiving the hollow, perforated spiral core support member.17. An apparatus for removing gas from a fluid mixture containing a gas component and a liquid component, comprising:means for receiving the fluid mixture in a cylindrical chamber; means for advancing the fluid mixture in a substantially helical path through the chamber such that the liquid component is urged radially outward while the gas component is urged radially inward; means for filtering the gas component from the liquid component; and means for discharging the gas component from the chamber. 18. The apparatus of claim 17, further comprising means for sealing the chamber to prevent leakage of the fluid mixture.19. An apparatus for removing gas from a fluid mixture containing a gas component and a liquid component, comprising:a cylindrical housing; a first inner flange and a second inner flange coaxially attached to a proximal end and a distal end, respectively, of the cylindrical housing; a spiral core mounted on a hollow, perforated spiral core support member and housed within the cylindrical housing; a membrane layer adjacent to an inner surface of the hollow, perforated spiral core support member and supported by a hollow, perforated membrane support member; first and second outer flanges connectable to the first and second inner flanges, respectively, each of the first and second outer flanges having a port therein for providing fluid communication with the cylindrical housing; an annular seal between the first inner flange and the first outer flange and between the second inner flange and a second outer flange, the annular seal disposed in an annular groove formed in each of the first and second outer flanges.
