Abstract
Abstract A separator suitable for separating a crude oil feed containing gas into gas and liquid the separator comprising a vessel (4) having an inlet (6) for feed disposed so that feed introduced under a pressure gradient is caused to form a downwardly flowing vortex of liquid from which an upwardly flowing vortex of gas separates, an upper outlet (10) for the vortex of gas comprising a pipe (8) extending downardly into the vessel from the top thereof, a lower outlet (16) for the liquid, the vessel further having located therein below the inlet (6) a downwardly extending hollow truncated cone (12) or cylinder to provide a surface for the downwardly flowing vortex of liquid, the walls (7) of the vessel (4) being spaced apart from the cone to provide therebetween a disengaging chamber (15) and an outlet (20) for the discharge of gas from the disengaging chamber.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
156 words
A separator suitable for separating a crude oil feed containing gas into gas and liquid the separator comprising a vessel having an inlet for feed disposed so that feed introduced under a pressure gradient is caused to form a downwardly flowing vortex of liquid from which an upwardly flowing vortex of gas separates, an upper outlet for the vortex of gas comprising a pipe extending downwardly into the vessel from the top thereof herein referred to as a vortex finder, a lower outlet for the liquid, the further vessel having located therein below the inlet, a downwardly extending hollow truncated cone to provide a surface for the downwardly flowing vortex of liquid, the walls of the vessel being spaced apart from the cone to provide therebetween a disengaging chamber and an outlet for the discharge of gas from the disengaging chamber characterised in that the truncated cone is a small angle cone (12) or a cylinder.
Claim 2
Dependent Claim
156 words
A separator suitable for separating a crude oil feed containing gas into gas and liquid the separator comprising a vessel having an inlet for feed disposed so that feed introduced under a pressure gradient is caused to form a downwardly flowing vortex of liquid from which an upwardly flowing vortex of gas separates, an upper outlet for the vortex of gas comprising a pipe extending downwardly into the vessel from the top thereof herein referred to as a vortex finder, a lower outlet for the liquid, the further vessel having located therein below the inlet, a downwardly extending hollow truncated cone to provide a surface for the downwardly flowing vortex of liquid, the walls of the vessel being spaced apart from the cone to provide therebetween a disengaging chamber and an outlet for the discharge of gas from the disengaging chamber characterised in that the truncated cone is a small angle cone (12) or a cylinder.
Claim 3
Dependent Claim
50 words
A separator as claimed in claim 1 characterised in that there is provided in the region of the lower end of the small angle cone (12) or cylinder a baffle (14) disposed transversely with respect to the- axis of the cylinder (12) to engage the downwardly flowing vortex of liquid.
Claim 4
Dependent Claim
65 words
A separator as claimed in claim 2 characterised in that the baffle is located below the lower end of the cone (12) or cylinder and is sized so as to provide a gap between its edges and the walls (7) of the vessel so that liquid on contacting the baffle (14) is caused to flow radially outwardly and pass into the vessel below the baffle.
Claim 5
Dependent Claim
46 words
A separator as claimed in claim 2 characterised in that there is provided below the baffle (14) a baffle assembly (20) comprising a plurality of plates (22, 24, 26, 28, 30 and 32) disposed radially with respect to the axis of the vessel (4) and vertically.
Claim 6
Dependent Claim
39 words
A separator as claimed in claim 1 characterised in that the lower outlet for the liquid is disposed so that liquid is withdrawn from near the base of the vessel (4) to reduce entrainment of gas in the liquid.
Claim 7
Dependent Claim
45 words
A separator as claimed in claim 5 characterised in that the lower outlet comprises a pipe (16) the lower end of which is located near the base of the vessel (4) to provide, in use, a liquid seal at the base of the vessel (4).
Claim 8
Dependent Claim
20 words
A separator as claimed in claim 1 characterised in that the vortex finder (8) is provided with a skirt (9).
