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.
