- the gasket arrangement is preferably a compressible electrically insulating material positioned on opposite sides of the mounting plate assembly, as first and second gasket members.
- the integral axially directed conductive portion is sized to project outwardly from opposite sides of the mounting plate assembly, in the same general direction of the gaskets.
- the arrangement is configured so that when the gaskets are compressed during use, the integral, axially directed, conductive portion of the mounting flange section comes into electrically conductive (grounding) contact with equipment in which the gas/liquid separator element is positioned in use.
- the integral, axially directed, conductive portion is a generally planar annular ring; and, the integral, axially directed, conductive portion includes: a bead in that annular ring directed in one axial direction, and an edge of the annular ring directed in an opposite direction.

- a component of typical of gas/liquid separator arrangements of the type of concern herein, is a removable and replaceable, i.e., serviceable, separator arrangement.
- the removable and replaceable (i.e., serviceable) separator arrangement generally includes at least one gas/liquid separator element (or separator element) that, in time (due to operation of the gas/liquid separator assembly) is removed and replaced during a servicing operation; hence the term "serviceable.”
- each serviceable separator element includes a media pack, through which the gasses are passed.
- Each media pack typically includes layers or stages of media for conduct of coalescing and drain steps. Components of the media pack are typically mounted on a mounting flange arrangement.
- the mounting flange arrangement allows the serviceable separator element to be appropriately positioned in a gas/liquid separator assembly or arrangement, for use.
- gas/liquid separator assemblies or separator elements will be characterized or classified as either "in-to-out flow” or “out-to-in flow,” depending on whether, in use, during gas flow through the media pack of each separator element, gas flow is directed from outside the serviceable separator element arrangement to an interior; or, from an interior of the serviceable separator element to an exterior. While the techniques described herein can be applied to either or both; many typical applications will be in association with out-to-in flow arrangements. Thus, the examples depicted in the drawings depict out-to-in flow arrangements.
- gas/oil separator for a compressor arrangement.
- Such an apparatus is generally adapted for operation with internal pressures on the order of at least about 60 psi (i.e., at least about 4.2 kilograms/sq. cm.), typically at least about 80 psi (i.e., at least about 5.6 kilograms/sq. cm.). Examples of use would be with compressors about 25 hp and up.
- some particular arrangements for air/oil separation in compressor systems are shown.
- the techniques and principles described herein can be applied in a variety of systems, and in a variety of sizes, for use with a wide variety of equipment types and sizes (for example a variety of compressors).
- the techniques described herein can be applied in other applications of gas/liquid separation; for example: in mist collector arrangements (air/liquid separators), such as industrial mist collectors; or, in air/water separators in compressed gas systems. Issues of application, relate to adaptation of the various techniques described herein, to such assemblies.

- Central aperture 29 is surrounded by a downwardly directed shroud 30; i.e., shroud 30 projects into lower region 25.
- Shroud 30 is preferably imperforate, and defines an open lower end 31.
- shroud 30 is cylindrical around central longitudinal axis 33 of vessel 4, although alternate shapes and locations for shroud 30 are possible.
- Serviceable separator element 35 is configured for out-to-in flow, for reasons apparent from the following.
- a gas/liquid mixture typically an air/oil mixture from a compressor system
- air/oil inlet 21, Fig. 1 in this instance into bottom region 25.
- the gas/liquid mixture is directed into a preferred flow pattern, in this instance in part around shroud 30.
- the flow pattern would be counter-clockwise, when viewed downwardly from the view point of Fig. 1, although alternate flow patterns can be accommodated.
- Liquid can be scavenged from upper sump 40, by a draw tube (not shown) extended through scavenge port 18, Fig. 1.
- the separated gasses (under pressure) can then escape from serviceable separator element 35, by passage through an open end or outflow aperture 45 of the element 35 and then outwardly from assembly 1 through air flow aperture 15.
- the serviceable separator element 35 depicted includes a media pack 50 and a mounting plate assembly 51.
- the mounting plate assembly 51 includes mounting flange section 55 and media pack mounting section 56.
- the mounting plate assembly 51 defines outflow aperture 45.

- end cap 52 is provided, including central sump 40 formed therein.
- End cap 52 may comprise a metal piece, or a plastic molded piece.
- the particular arrangement shown utilizes a metal end cap for end cap 52, secured to end 50b and media pack 50 by an appropriate adhesive or potting agent.
- a seal is needed between the mounting flange section 55 and each of the top plate 6 and plate 12, in order to ensure appropriate maintenance of the environment within pressure vessel 4.
- gasket rings 61, 62 positioned on opposite sides 55a, 55b of mounting flange section 55, respectively.
- Gasket rings of the type used for gasket rings 61, 62 are typically pre- made by being cut from a sheet compressed fiber material.
- Example of a useable gasket materials are commercially available under the trade designations Klinger 4401 and Klinger 4201 from Thermoseal, Inc., Sidney, OH 45365.
- Such gaskets usually comprise Kevlar fibers or similar material. Typical such gaskets are about 0.06 inches (1.5 mm.) thick (non- compressed).
- the gaskets are typically adhered to the flange section 55 using a liquid adhesive, or the gaskets are coated on one face with the pressure sensitive adhesive (psa).
- the gaskets usually do not compress in thickness very much when the mounting plate assembly 51 is installed in assembly 1, during use.
- Typical gasket materials such as Klinger 4401 and 4201, are electrically insulating.
- the mounting plate assembly 51 of the serviceable separator element 35 is electrically insulated from both the top cover 6 and the remainder of the pressure vessel 4, by the gasket rings 61, 62. In many instances, it is required that the mounting plate assembly 51 be electrically grounded to a remainder of the gas/liquid separator assembly 1.
- each staple is driven through one of the gaskets into contact with the mounting flange section, in a region of the gaskets centrally positioned between the outside edges 61a, 62a and the inside edges 61b, 62b, of each gasket (61, 62).
- Such staples are usually about 0.5 inch to 1 inch wide (1.25 - 2.54 cm). It is desirable to avoid the need for such pre-made gaskets, if possible.
- vessel 4 includes a fill port 70, for ensuring an appropriate oil level, for example at start up.
- a lower drain 71 is positioned in a lower sump 38.
- a site glass 72 is provided, for viewing the oil level 39.
- the pressure vessel 4 may be provided with various taps for control systems and monitoring. For the particular arrangement shown, a pressure relief tap 73 and temperature probe port 74 are shown. In addition, a control port 75 and a pressure tap 76 are shown.
- gas/liquid separators of the type of concern here are provided with one of two types of gas inlet arrangements.
- a first, generally referred to herein as a tangential gas inlet is a gas inlet which has a center line directed generally tangentially with respect to the rounded or cylindrical outside wall 8 of the vessel 4.
- Inlet 21 is a tangential inlet.
- a second type of gas inlet is generally referred to herein as a "radial” or “radially directed” inlet. Such an inlet would generally be directed toward central longitudinal axis 33 of the assembly 1. No radial inlet is depicted herein, however one can be used with the various techniques described herein.
- a radial inlet is depicted in U.S. Provisional Patent Application Serial No. 60/431,432 (filed December 6, 2002) at reference numeral 12; the complete disclosure of U.S. Provisional Patent Application Serial No. 60/431,432 being incorporated herein by reference.
- media pack 50 typical media packs include a coalescing stage 83 and a drain stage 84. For the particular serviceable separator element 35 depicted, the coalescing stage 83 and drain stage 84 are both permanently secured within the serviceable separator element 35.
- FIG. 4 the gas/liquid separation assembly 99 is depicted.
- Assembly 99, Fig. 4 is the same as assembly 1, Fig. 1, however with an improved serviceable separator element 100 mounted therein. Except for the improved serviceable separator element 100, the assembly 99 of Fig. 4, can be the same as the assembly 1, Fig. 1. That is, the assembly 99 includes a top cover and pressure vessel arrangement, indeed the identical vessel 4 and top cover 6 arrangement as in Fig. 1 are shown. In Fig. 4, identical reference numerals are thus used, where appropriate, to reference identical or analogous parts.
- serviceable separator 100 includes media pack 102, with ends 102a, 102b, and mounting plate assembly 103.
- end piece or cap 104 at an opposite end 102b of the media pack 102 from mounting plate assembly 103.
- the end cap 104 defines internal sump 105.

- Mounting plate assembly 103 includes mounting flange section 110 and media pack mounting section 111.
- Media pack mounting section 111 includes base Ilia, inner lip 11 lb and outer lip 111c.
- the mounting flange section 110 is attached to base 11 la by wall 112.
- mounting flange section 110, wall 112, base I lia and lip 11 lb are integral with one another, each being a section of a single, integral metal, piece.
- Flange 11 lc is a part of a separate metal piece secured to base I l ia, for example by welding to flange 111; flange 111c being integral with a base piece l id, Fig. 7.
- the mounting plate 103 is shown in Fig. 7, without the media pack thereon.
- base 11 la is generally planar, and is in a plane separate from the plane in which mounting flange 110 is positioned; the separation being by section 112, and bends 112a, 112b.
- Alternate arrangements in which base Ilia and mounting flange 110 are in the same plane are possible, as discussed below in connection with Figs. 8 and 9.
- the mounting flange section 110 includes section 114 and section
- Section 114 for the specific example shown, is planar, although alternatives are possible, and has first and second opposite sides 114a, 114b.
- Section 115 for the embodiment shown, is configured to have at least a portion 115a projecting axially away from side 114a; and, a portion 115b projecting axially away from side 114b.
- portion 115a projects axially away from side 114a, it is meant that it projects in a direction generally parallel to central axis 120, in a direction outwardly from a plane defined by side 114a, since side 114a is planar.
- the non-planar section 115 comprises a formation which, in cross-section, includes a rib or bump 117, in section
- portions 115a and 115b each project axially at least 0.05 inch (about
- edge 117 projects outwardly from surface 114a, and the edge (corresponding to edge
- a gasket ring 122 is shown positioned on surface 114a, and an opposite gasket ring 123 is shown positioned on surface 114b.
- gasket rings 122, 123 are identical to one another, and are positioned as mirror images, although alternates are possible.
- gasket rings 122, 123 together form a gasket arrangement, 124.
- gasket arrangement in an initially applied, non-compressed, configuration as shown in
- each gasket ring 122, 123 extends further, axially, from its associated surface portion (114a, 114b respectively), than the associated portion (115a, 115b respectively) of the non-planar section 115.
- gasket 122 projects axially outwardly from surface 114a further than does edge 118; and, gasket 123 projects axially outwardly further from surface 114b than does bump 117.
- Figs. 4 and 5 it can be seen that mounting flange section 110 is positioned between top cover 6 and plate 12. Referring to Fig. 5, an enlarged fragmentary view of a portion of Fig. 4, tightening of the bolts (Fig.
- non- planar section 115 provides (when the mounting plate assembly 103 is installed and the gasket material is compressed), for electrically conductive contact between and among top plate 6, mounting plate 103 and the pressure vessel bottom section 4a.
- the non-planar section 115 also provides for a compression stop.
- non-planar section 115 provides for electrically conductive contact between and among top plate 6, mounting plate 103 and pressure vessel bottom section 4a, when the gas/liquid separator element is mounted with mounting plate section 110 trapped between cover 6 and pressure vessel bottom section 4a, and the gasket arrangement 124 is sufficiently compressed to the compression stop. Further, for the particular preferred arrangement shown, the non-planar section 115 is integral with a remainder of the moimting plate assembly 103.
- gaskets 122, 123 are formed from a flowable, thixotropic, material applied as a continuous bead, to the surfaces 114a, 114b respectively.
- One such material would be a two component polyurethane such as: Part A K31-9308-1-NP3; Part B K31-B81, available from Automated Dispensing Solutions, Inc., Circle Pines, M ⁇ 55014, a distributor for Sonderhoff GMBH, Koln, Germany. It is generally expected that what will be preferred will be a gasket which compresses at least 25%, preferably at least 35% and most preferably to an extent within the range of 40-60% inclusive (in thickness) in use during sealing; usually about 50%. It is anticipated that a typical non-compressed thickness for each gasket 122, 123 would be at least 0.1 inch (2.5 mm) and typically within the range of 0.1 - 0.13 inch (2.5 - 3.3 mm).
- the bump 117 projects outwardly axially from surface 114b by a distance of half the thickness of a gasket; and the edge 118 projects axially outwardly from plane defined by surface 114a, by a distance of half the thickness of the gasket.
- gaskets which are applied to mounting plate flanges in the form of a flowable bead will be referred to as "mold-in-place gaskets.”
- the term “mold-in-place gasket” is meant to exclude, from its definition, pre-formed gaskets that are cut from material and which are then applied to a mounting plate arrangement.
- mold-in-place gasket is not meant to refer to any particular shape of gasket or any particular material used for the gasket, unless otherwise defined. However it is meant to reference a gasket that results from flowing a flowable material, applied the appropriate location, with or without use of a form or mold.
- a “non-compressed" thickness of the gasket material reference is meant to the gasket material thickness prior to it having been compressed, even for the first time, in mounting, after it has been molded in place. It is not a requirement that the gasket material be of a type which will fully rebound to its initial non-compressed state, after the gas/liquid separator element has been mounted once, and then the top cover is removed to allow the element to be serviced.
- projection 118 circumscribes seal 122; and, projection 117 circumscribes seal 123, Fig. 5.
- the particular projection member 117 depicted comprises a radially continuous convex bead opposite a radially continuous concave groove; and, projection 118 comprises a radially continuous edge. Attention is directed to Fig. 7, in which the mounting flange arrangement 103 is depicted without the media pack mounted thereon.
- a variety of cross-sectional shapes can be used, when a bead 117 is used for one of the projections in portion 115. Although a semi-circular shape of the bead can be used, it is anticipated that in typical instances the seal bead (non-compressed) will be a little wider than it is high.
- the size of the bead preferred may depend upon the particular size of the unit. An example of a useable size is a radius approximately within the range of about 0.2 - 0.3 inches (5-7.5 mm).
- the specific construction in the media pack is not critical to the general principles of the assembly configuration described herein, and is a matter of choice. In general, the size and construction of the media pack will be selected based upon such issues as air flow, the level of efficiency of separation desired, the amount of restriction acceptable, the lifetime of use preferred and the size and space available. A characterization of some possibilities is provided in Section IN below.
- FIG. 8 an alternate mounting plate assembly, minus gaskets, to the mounting plate assembly utilized in the embodiment of Figs. 4-7 as shown.
- mounting plate assembly 150 is depicted.
- the mounting plate assembly includes gas outlet flow flange 151 and region 152.
- Region 152 provides for: portion 153 as media pack mounting portion; and, portion 154 as an integral, ' axially directed, electrically conductive arrangement.
- Portion 154 comprises a bead 155 and edge 156, analogous to the arrangement of Fig. 6.
- Attention is now directed to Fig. 9, which shows mounting plate assembly 150 with gasket arrangement 160 thereon, comprising bead 161 and bead 162, on opposite sides of section 152.
- the portion of the mounting plate at 165, whereat the beads 161, 162 are located, would be the mounting flange.
- FIG. 9 can be utilized analogously to that of Fig. 4, simply with the media pack secured to a portion of the mounting plate (at 153) coplanar with a portion (at 165) to which the gasket material 160 is applied.
- the same advantages relating to electrical conductivity would result, during use. From a comparison of Figures 8 and 9 with the embodiment of Fig. 6, it will be apparent that a variety of arrangements can be utilized. In addition, alternates to the edge, bead arrangement can be used, to accomplish the integral axially projection to accomplish the electrical conductivity or grounding contact, during compression of the gasket arrangement. Further, there is no specific requirement that the region to which the media pack is secured be planar, although this would be preferred in many systems and arrangements.
- Mounting plate assemblies of the type shown in Figs. 6, 7, 8 and 9, can be made by metal forming techniques such as stamping and spinning, with separate parts (if used) attached for example by welds. Thus, the shapes can be relatively inexpensively obtained.
- the coalescing stage comprises appropriate material to cause coalescing of an entrained liquid particles within an air stream passing into the coalescing stage.
- the drain stage operates to collect coalesced particles, to facilitate drainage from the media pack.
- the coalescing stage will be positioned in the element, to be upstream from the drain stage.
- the coalescing stage is positioned around drain stage.
- a drain stage 140 is positioned surrounded by a coalescing stage 141, and spaced therefrom by central liner 142.
- the central liner may comprise a variety of materials, for example a porous metal or plastic screen. An expanded metal screen can be used, for example.
- the media pack can be provided with upstream and/or downstream liners, if desired. It is anticipated that the coalescing stage may comprise a formed media.
- the drain stage at least in some instances, would comprise a wrapped felt or other air laid material.
- a polyester felt or similar material For example a polyester felt or similar material.
- the thickness of the coalescing stage and drain stage may be varied, depending on the particular system.
- a typical example would be: a coalescing medium having a thickness of about 0.4 - 0.6 inches (about 10-15 mm), for example about 0.5 inches (12.5 mm); and, a drain stage medium having an overall thickness of about 0.2 - 0.3 inches (5-7.6 mm), for example 0.25 inches (6.4 mm).
- the coalescing stage may comprise formed media.
- foreign media comprises media construction by deposition of media fibers on to a form or mandrel, from suspension. Adhesives may be applied and/or binder fibers may be used, to help retain the form shape on the mandrel. It is noted that for the embodiments depicted the entire media pack is secured to the mounting plate assembly. This is not a specific requirement of application of principles according to the present invention.
- the mounting flange arrangement may have secured thereto only a selected portion of the media pack arrangement, with the remainder of the media pack arrangement either being removeably mounted, or mounted on a separate component.
- An example of such a possibility, that can be adapted to apply the principles of the present disclosure, is shown in U.S. 6,585,790 at Fig. 7, the complete disclosure of
- a gas/liquid separator element which, in assembly and use, provides advantage.
- a principal advantage is provided by manufacturing a mounting plate assembly at the separator element from an electrically conductive material with an integral, axially projecting, portion thereon, which will come into contact with the top plate and housing arrangement, when installed and when an appropriately positioned gasket arrangement is compressed during sealing.
- a particularly advantageous arrangement which involves an axially projecting bead and an axially projecting edge, is provided.
- the techniques can be advantageously applied with a variety of types of gaskets.
- a particularly advantageous gasket arrangement which involves compressible flowable material applied to the mounting plate assembly as a mold-in-place gasket, is described and shown.
- Such an arrangement is particularly advantageous, since it avoids the use of pre-made or pre-cut materials.
- a material When such a material is chosen, it is preferably one which will compress in thickness at least 25%, preferably at least 35%, and most preferably within the range of 40%-60% inclusive, in use.
- Such arrangements are generally referred to herein as "mold-in- place" gaskets.
- the gaskets are typically from an electrically insulating material, such as a compressible polyurethane.
- the gasket arrangement of the preferred gas/liquid separator elements can be characterized as having a first, compressible, electrically insulating gasket member positioned on a first side of an annular mounting flange; and, a second, compressible, electrically insulating gasket member positioned on a second side of the annular mounting flange.
- each can be characterized as having a first, non-compressed, configuration in which it projects outwardly in greater relief, relative to a portion of the mounting flange section on which it is mounted, than does an axially directed conducted portion of that mounting flange; and, a second, compressed, configuration in which the gasket member does not project outwardly in greater relief, from a portion of the mounting flange section in which it is mounted, then does an axially directed conductive portion.
- the principles described can be characterized as involving the provision of a gas/liquid separator arrangement as characterized, with a preferred mounting plate assembly as described, operably mounted in a pressure vessel of a gas/liquid separation assembly. Further principles apply to methods of installation of gas/liquid separator assemblies, and their use. Also methods of assembling preferred gas/liquid separator elements through formation of preferred mounting plate assemblies, are provided.
