Abstract
An improved oil/gas separator having an upright cylindrical housing with a radial oil/gas inlet and a gas outlet pipe arranged within the housing downward and terminating within the housing with an open end. A helical wall is mounted coaxially around the gas outlet pipe and an oil collection zone is arranged below the open end of the gas outlet pipe. A drip ring is mounted at a low end portion of the gas outlet pipe adjacent to the open end to prevent oil from being entrained into the gas proceeding into the open end. A replaceable porous filter can be provided above an exit end of the gas outlet pipe for a last stage of oil removal from the gas flowing through the separator. A baffle is arranged below the porous filter and above the helical wall for collecting oil removed by the porous filter.
Claims27
A device for separating oil from a gas comprising:
- a housing having a peripheral wall and a bottom wall;
- an oil/gas inlet into said housing;
- a gas outlet through said housing;
- a cylindrical wall forming a central passage within said housing and having an inlet opening within said housing, said cylindrical wall in flow communication with said gas outlet;
- a helical wall formed within said housing between said peripheral wall and said cylindrical wall;
- an oil collection zone arranged below said helical wall;
- an oil outlet arranged through said housing in said oil collection zone;
- a baffle arranged around said cylindrical wall projecting radially therefrom and located between said helical wall and said inlet opening of said cylindrical wall for directing oil radially outwardly from said cylindrical wall;
- and
- means for collecting and separating oil from said oil/gas mixture located in a space between said helical wall and said peripheral wall.
A device for separating oil from a gas comprising:
- a cylindrical housing formed by a peripheral wall having a vertical axis and having closed top and bottom ends;
- an oil/gas mixture inlet extending radially to said axis of said peripheral wall through said peripheral wall;
- a gas outlet formed by a cylindrical wall extending through said housing and having a lower open end interior of said housing, said cylindrical wall forming a central passage coaxial with said peripheral wall;
- a helical wall extending from said cylindrical wall towards said peripheral wall;
- an oil collection zone below said cylindrical wall;
- and
- an oil outlet in said oil collection zone;
- and
- means arranged between said helical wall and said lower open end of said cylindrical wall for preventing oil dripping down said cylindrical wall from entering said lower open end of said cylindrical wall.
A device according to claim 16, wherein said baffle comprises a ring shape sloping downwardly and outwardly.
A device for separating oil from a gas comprising:
- a vertical axis housing formed by a peripheral wall and having closed top and bottom ends;
- an oil/gas mixture inlet provided adjacent to said closed top end;
- a gas outlet conduit formed by a cylindrical wall extending through said top end and having a lower open end interior of said housing, said cylindrical wall forming a central passage coaxial with said axis;
- a helical wall extending more than a full revolution about said axis, extending from said cylindrical wall towards, but terminating radially inwardly of said peripheral wall, and extending from an area adjacent said top end and terminating above said bottom end;
- an oil collection zone;
- baffle means arranged above said oil collection zone for preventing turbulent
- gas from influencing oil collected in the oil collection zone;
- an oil outlet in said oil collection zone;
- and
- a solid annular drip ring attached to said cylindrical wall, below said helical wall and above said lower open end, and extending radially outwardly therefrom, said drip ring having a continuous conical top surface.
A device for separating oil from a gas, comprising:
- a housing having a peripheral wall and a bottom wall;
- an oil/gas inlet into said housing;
- a gas outlet formed by a cylindrical wall forming a central passage within said housing and having an opening within said housing;
- a helical wall formed within said housing between said peripheral wall and said cylindrical wall;
- an oil collection zone arranged below said helical wall;
- an oil outlet arranged through said housing in said oil collection zone;
- and
- a screen connected to said cylindrical wall and covering said opening of said gas outlet.
A device for separating oil from a gas, comprising:
- a housing having a peripheral wall and a bottom wall;
- an oil/gas inlet into said housing;
- a gas outlet through said housing;
- a cylindrical wall forming a central passage within said housing and having an inlet opening within said housing, said cylindrical wall in flow communication with said gas outlet;
- a helical wall formed within said housing between said peripheral wall and said cylindrical wall;
- an oil collection zone arranged below said helical wall;
- an oil outlet arranged through said housing in said oil collection zone;
- and
- a porous filter arranged between said gas outlet and said cylindrical wall, said porous filter arranged to communicate gas from said cylindrical wall to said gas outlet.
