| A method for separating a vapor from a carrier gas is disclosed. An air-sparged hydrocyclone is provided with a porous sparger covered by an outer gas plenum. A cryogenic liquid is provided to the tangential feed inlet at a velocity that induces a tangential flow and a cyclone vortex in the cyclone. The carrier gas is injected into the air-sparged hydrocyclone through the porous sparger. The vapor dissolves, condenses, desublimates, or a combination thereof, forming a vapor-depleted carrier gas and a vapor-enriched cryogenic liquid. The vapor-depleted gas is drawn through a vortex finder while the vapor-enriched cryogenic liquid is drawn through an apex nozzle outlet. In this manner, the vapor is removed from the carrier gas. | ||||||

| 6 | Apparatus for enhancing venturi suction in eductor mixers | US10979793 | 2004-11-01 | US07776213B2 | 2010-08-17 | Johnny Arnaud |
| An apparatus is provided for suction of a secondary fluid into a primary fluid through one or multiple gaps in contact with a venturi. The venturi imparts a high velocity on the primary fluid to flow across a gap in contact with the venturi and draw in the secondary fluid. The apparatus employs a linear venturi with the flow area, or opening, in the form of a narrow ring or narrow rectangle to increase the length of the gap in contact with the venturi. One gap is provided and positioned in contact with one side of the narrow venturi opening, or two gaps are provided having one positioned in contact each side of the narrow venturi opening. The linear venturi is housed in assemblies referred to as “eductors.” Various eductor embodiments are provided including: 1), cylindrical housings with one or multiple concentric linear venturi with openings in the form of narrow rings; 2), rectangular housings with a single rectangular linear venturi with an opening in the form of a narrow rectangle, with multiple rectangular linear venturi with inlets positioned around a primary fluid inlet to flow radially outward through the multiple venturi, with multiple rectangular linear venturi with outlets positioned around a mixing chamber to cause circulation of the flow of fluids; 3), a cylindrical housing with linear venturi with an opening in the form of a narrow ring adapted for inserting into piping; and 4), cylindrical housings with linear venturi with an opening in the form of a wide ring adapted for installation in piping. | ||||||

| 8 | Air sparged hydrocyclone flotation apparatus and methods for separating particles from a particulate suspension | US194823 | 1988-05-17 | US4838434A | 1989-06-13 | Jan D. Miller; Ye Yi |
| The present invention is directed to air sparged hydrocyclone flotation apparatus and methods for separating particles from particulate suspensions (such as coal and mineral ore slurries), wherein fluid discharge is removed annularly from a flotation vessel. Preferably, the flotation apparatus includes a vertically oriented cylindrical flotation vessel having a tangential inlet at its upper end and an annular outlet at its lower end. The annular outlet allows for the smooth exit of fluid discharge from the flotation vessel so as to avoid disturbance of the fluid flow within the flotation vessel. Air is sparged into the vessel and a froth which contains the recovery products exits through a vortex finder positioned in the upper end of the vessel. The apparatus includes a froth pedestal positioned within the vessel which forms the annular outlet with the wall of the vessel. The froth pedestal may take a generally cylindrical or a generally conical configuration. The conical froth pedestal extends into the vessel from near the bottom of the vessel to at least one-half the distance to the vortex finder. The froth pedestal further serves, among other things, to support the froth column formed within the flotation vessel and isolate the froth column from the fluid discharge so as to minimize mixing therebetween. | ||||||

| A process for removing dissolved and undissolved oil and chemical additives from waste and/or produced water streams involves contacting a first gas with the produced water stream, the first gas utilizing hydrogen bonding and dipole interactions with the contaminants to remove them from the water. The rise rate of the first gas is accelerated by mixing a second, more buoyant gas with the first gas. The first gas and second gas are recovered by the application of a vacuum to the waste stream after treatment. The first gas is separated from the second gas by compressing and cooling the combined gas stream, venting the majority of the second gas stream while the first gas is liquified, then expanding the first gas before returning it to the flotation vessel. The first and second gases are mixed with the contaminated water stream at line pressure so that mixing is intimate and flotation is accelerated. | ||||||

A hydrocyclone (10) establishes a first vortex (15) of fluent material at one end (e.g. in a top portion 4), and a second vortex at the other end (e.g. in a bottom portion 24). The first vortex is established within a porous surface of revolution (18) to which gas or other fluid is supplied, passing through the porous surface into the first vortex. The second vortex is established by a conical end section (24) extending outwardly from (e.g. below) the porous surface, and with an axial (e.g. bottom 23) discharge for fluent material. Some fluent material -- for example having heavy particles -- is removed tangentially from the conical end section at a portion (35) near the porous surface of revolution. A conical shroud (25) having a circumferential periphery is mounted by a number of spaced legs (28) connected between the shroud and the conical bottom section so that fluent material may pass (thru 32) between the circumferential periphery of the shroud and the porous surface of revolution. An axial gas passage (27) is provided in the shroud to allow gas to escape from the second vortex into the first vortex, and ultimately out the first end (e.g. top) of the hydrocyclone (Figure 1). |

| PURPOSE: To improve the diversity and efficiency of a gas-sparged hydrocyclone. CONSTITUTION: This hydrocyclone has a means for establishing a vortex action in a volume between the bottom (second end) 21 of the porous surface of a hollow main body and the second withdrawal means or outlet 23, to effect separation of some or substantially all of the remaining gases in the fluent material when it reaches the bottom 21 of the porous surface of revolution 18. The revolution means comprises a shroud means 25 disposed above a conical bottom (second end) section 24 (e.g. sharply tapered), a means 28 for forming the shroud means and the central axially extending passage 27 of the conical interior passage 30 of the shroud means 25. A gas separated in the conical bottom section 24 by the other revolution means is joined to a gas separated by a revolution flow 15 in the hollow main body and then discharged from a gas withdrawal conduit 14 at the top. High density and larger particles move toward the wall where they are extracted through a generally tangential outlet nozzle 35. The accepted slurry flows downwardly toward the outlet 23.
