Abstract
Abstract A high pressure gas/oil separator comprising a pressure vessel with a magnetically driven hollow shaft extending thereinto. The shaft has a slinger at its lower end within the vessel. The upper end of the shaft is in communication with a source of the gas/oil mixture. The vessel has a purified gas outlet above the slinger. Gas/oil mixture is thrown by centrifugal force against walls of the vessel and the oil coalesces on the walls and drains to the bottom of the vessel. The purified gas escapes from the vessel through the outlet port.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
142 words
An apparatus for separating oil and gas at high pressures comprising: a pressure vessel having an open end; a cover closing the open end of said pressure vessel, said cover having an elongate non-magnetic hollow extension; a hollow driven shaft journaled in said elongate non-magnetic hollow extension, said shaft extending downwardly into the pressure vessel; a plug with an inlet opening for an oil/gas mixture fixed in an end of said extension which is positioned in said cover, said opening being in communication with the interior of the hollow shaft; impeller means at the end of the hollow shaft within said vessel for throwing the oil/gas mixture against the sides of the vessel so as to separate oil from gas; magnetic means for driving the hollow driven shaft in the elongate non-magnetic hollow extension; and an outlet port for the purified gas.
Claim 2
Independent Claim
142 words
An apparatus for separating oil and gas at high pressures comprising: a pressure vessel having an open end; a cover closing the open end of said pressure vessel, said cover having an elongate non-magnetic hollow extension; a hollow driven shaft journaled in said elongate non-magnetic hollow extension, said shaft extending downwardly into the pressure vessel; a plug with an inlet opening for an oil/gas mixture fixed in an end of said extension which is positioned in said cover, said opening being in communication with the interior of the hollow shaft; impeller means at the end of the hollow shaft within said vessel for throwing the oil/gas mixture against the sides of the vessel so as to separate oil from gas; magnetic means for driving the hollow driven shaft in the elongate non-magnetic hollow extension; and an outlet port for the purified gas.
Claim 3
Dependent Claim
46 words
Apparatus according to claim 1 wherein the magnet means for driving the driven shaft comprises a drive magnet assembly having permanent magnets and being journaled to the exterior of the non-magnetic extension and a driven magnet assembly having permanent magnets fixed to the hollow driven shaft.
Claim 4
Dependent Claim
33 words
Apparatus according to claim 1 wherein a splash plate comprising a disk having a diameter less than the inner diameter of the vessel is mounted to the hollow driven shaft above the impeller.
Claim 5
Dependent Claim
29 words
Apparatus according to claim 1 wherein a filter is mounted to the vessel above the impeller and below the outlet port separating the vessel into inlet and outlet chambers.
