Definitions
- Vapor-liquid mixtures are often encountered in the process industries.
- the dispersion of liquids in gas streams include unstable mixtures which usually must be separated prior to further processing of the phases. Most dispersions will separate naturally if left undisturbed, however, the natural separation rate is often too slow for economic con ⁇ sideration.
- One variety of artificial separator commonly employed to accelerate the separation rate of dispersion utilizes centrifugal force of the entrained droplets for separation.
- a second variety relies upon the impingement and coalescing of the entrained liquid upon a suitable obstruction placed in the path of the flow stream.
- An object of the present invention is to achieve ef ⁇ ficient phase separation with minimum pressure drop in an inline installation without the use of complicated structure.
- the liquid trapped in the separation chamber flows by gravity through one or more downcomers to a separate liqui accumulation chamber.
- a normal liq level is maintained as a vapor barrier by means of suitabl level control apparatus, and the liquid is withdrawn from the bottom of the accumulation chamber at a rate equal to the liquid collection rate.
- a pipe 24 is disposed in the chamber 14 in substantial coaxial alignment with the inlet tubing 18, and has one end thereof swaged inwardly as shown at 26 to form a generally frusto-conical outer facing.
- the inner periphery of the opposite end of the pipe 24 is beveled outwardly as shown at 29 in a generally frusto-conical shape.
- the swaged end 26 of pipe 24 is inserted in the beveled end 22 of inlet tubing 18 but spaced apart therefrom to form an annular orifice 30 flaring outwardly in a downstream direction.
- the tubing 18 and the pipe 24 are secured in spaced but aligned relationship by spacer elements 32 which span the orifice 30 and are secured between the inlet tubing 18 and pipe 24 in any suitable manner (not shown) .
- the pipe 24 is preferably concentrically disposed within the housing 12 and may be supported therein by numerous means; but as shown in FIGURE 1, the pipe 24 is supported by a plurality of struts 34 secured between the outer periphery of the pipe and the inner periphery of the housing 12.
- a pair of pipes 36 and 38 is coaxially aligned behind pipe 24 in spaced swage-to-bevel sequence by means of spacer elements 32 to provide additional orifices 40 and 42 which are substantial ⁇ ly identical to the orifice 30.
- the pipes 36 and 38 are preferably supported in the chamber 14 by struts 34 attached to the inner periphery of the .housing wall 12.
- a baffle 44 having an inwardly directed substantially conical face 43, is coaxially aligned with pipe 38 and spaced apart from the beveled end 29 thereof by means of axially extending circu ferentially spaced rib members 46 secured between pipe 38 and the baffle base 41.
- the cone apex of baffle 44 is directed toward the end of pipe 38, and the base 41 of the cone is extended radially to form a circumferential cup-like projection 45 as shown in FIGURE 2.
- E xhaust tubing 48 is disposed in substantial coaxial alignment with inlet tubing 18 and spaced downstream from the baffle 44.
- the exhaust tubing 48 extends from the interior of chamber 14 through a central aperture 49 pro- vided in the right-hand head 16, as viewed in FIGURE 1.
- a second housing 54 is secured beneath housing 12 and provides a liquid accumulation chamber 56.
- a pair of down co ers 50 and 52 are secured to the lower portion of housi 12 in open communication with chamber 14 and extend downwa ly through the upper wall of housing 54 into open communic tion with the liquid accumulation chamber 56.
- a liquid dr line 58 is connected to the bottom of housing 54 in open communication with chamber 56 for withdrawal of liquid the from.
- a control valve 60 is interposed in the draw line 5 and is operated by a suitable valve actuator 64 which is operably connected to a float 62 which is disposed in the chamber 56.
- the valve 60 is preferably preset to open whe the liquid level maintained in the accumulator chamber ex ⁇ ceeds a predetermined normal level.
- a vapor-liquid mixture (not shown) is continuously fed into inlet tubing 18.
- the spiral vanes 20, located in tubing 18, impart a helical motion to the flow stream, and the heavier liquid components thereof are forced to the outer perimeter of the swirling flow by cen ⁇ trifugal force.
- the separated liquid droplets exit from the main flow stream through the orifices 30, 40, and 42, and fall to the bottom of chamber 14 by gravity.
- the flow stream exiting from the beveled end of the pipe 38 and any remaining droplets contained therein is directed against conical baffle 44.
- Baffle 44 reverses the generally forward flow of the stream and any droplets impinging on the baffle are coalesced and fall to the bottom of chamber 14.
- the flow stream exits the chamber 14 through the exhaust tubing 48.
- Liquid in the chamber drains therefrom by gravity flow via downcomers 50 and 52 into the liquid accumu ⁇ lation chamber 56.
- the separated liquid is withdrawn from chamber 56 through drain line 58.
- Control valve 60 operated by float 62 and valve actuator 64, maintains a liquid level in the liquid accumulation chamber 56 at a predetermined level at all times, thus preventing escape of vapor there ⁇ through while withdrawing liquid at the rate of accumulation.
- the invention disclosed operates with relatively low pressure drop and eliminates the need for conventional demister pads while achieving high separation efficiencies.
