[0018]

[0027] The components of the present invention will now be described in more detail, with like components having like reference numerals.

[0028] Using the exemplary embodiments shown in FIGS. 1A-1B, FIG. 2, FIGS. 7B, and FIG. 7C for reference, the illustrated support 500 of the coalescer filter element is

[0029] (a) A first end 100 including a first end piece 101, the first end piece having a first end annular channel 102 having an outer surface 101A and an inner surface 101B and first and second channel sidewalls 102A, 102B connected to the inner surface, and a central opening 107 penetrating the outer and inner surfaces, the central opening providing at least three fluid channel openings 103, 104, 105 penetrating the outer and inner surfaces (see Figures 1B, 2, 7A-7B, which also show a fourth fluid channel opening 106 resulting from the insertion of the fluid flow bar 300),

[0030] (b) A second end 200 including a second end piece 201, the second end piece having an outer surface 201A and an inner surface 201B and a second end annular channel 202 having first and second channel sidewalls 202A, 202B connected to the inner surface and a central opening 207 penetrating the outer and inner surfaces, the second end piece including a hollow fitting 210 penetrating the central opening 207, the hollow fitting having an inlet end 211 and an outlet end 212 and a sidewall 215 having at least two openings 215A, 215B penetrating the sidewall, the outlet end extending outward from the outer surface, the first end comprising a first end 301 and a second end 302 (indicated as a central slot 310 and notches 312(312A, 312B, 312C, see Figure 3) (If present, the notch may allow the fluid flow to continue flowing from the support if one or more openings of the hollow fixture are blocked) and connected to the second end by a fluid flow bar 300 having at least three arms 351, 352, 353 providing at least three fluid channels 303, 304, 305 extending from the first ends 100, 301 to the second ends 200, 303 (the embodiment of the fluid flow bar 300 shown in Figures 1A and 3 shows a fourth arm 354, a fourth fluid channel 306, and a fourth notch 312D), the fluid flow bar, illustrated arms, and illustrated fluid channels have a longitudinal axis from the first end 301 to the second end 302, and each of the illustrated fluid channels has first and second solid sidewalls (303A,The first and second solid sidewalls have inner and outer sides (313A, 313A', 313B, 313B', 314A, 314A', 314B, 314B', 315A, 315A', 315B, 315B', 316A, 316A', 316B, 316B'), and the inner side of the first solid wall is connected to the inner side of the second solid wall (as shown in figure 323 (313A is 31 The channels are connected (e.g., welded to each other), with the outside of the first solid wall spaced apart from the outside of the second solid wall (e.g., 313A' is spaced apart from 313B', and the spaces are shown as 333, 334, 335, 336, and generally forming a "V-shaped" fluid channel. (Also shown), each of the four arms in the illustration has a solid sidewall on one side for one fluid channel and a solid sidewall on the other side for a different fluid channel (for example, using Figure 3 for reference, arm 352 has a solid wall 303B for fluid channel 303 on one side and a solid wall 306A for fluid channel 306 on the other side), and each of the illustrated fluid channels communicates separately with its respective fluid channel opening at the first end (303 is connected to 103). The hollow fitting 210 and at least two openings (215A, 215B, and a third and fourth additional opening 215C and 215D are further shown in Figure 5B) are in fluid communication with the illustrated fluid channel at the second end 200, and the hollow fitting 210 is positioned in the slot 310 at the end 302 of the fluid flow bar 300 adjacent to the second end 200.

[0019]

[0031] The use of at least two openings 215A, 215B (and at least one of 215C and 215D) is desirable to allow the discharge of liquid from the hollow cylindrical coalescer filter element into the fluid receiving container 700.

[0020]

[0032] Typically, seals such as knife-edge seals 103C, 203C are positioned within the annular channels 102, 202 to contact and seal the ends of the hollow cylindrical coalescer filter element, as shown in Figure 7B.

[0021]

[0033] In some embodiments, as shown in Figure 7B, the outer side wall 108 of the first end piece 101 includes a groove 109 for receiving an elastic annular member 115, such as an O-ring, which can reduce or prevent bypass between the first end 100 and a filter plate, for example, a filter plate 2015 or a first filter plate 2015A used in a coalescer assembly (see, for example, Figures 9A-9B).

[0022]

[0034] In these illustrated embodiments, the hollow mounting fixture 210 has a threaded outer surface 216, and the illustrated embodiments have two sets of threads (see Figures 5A and 5B).

[0023]

[0035] Typically, the first end piece 101 (shown with a flange) may be sandwiched between filter plates, or optionally include two or more slots for retainers such as screws or pins (not shown) for connection to, for example, a coalescer assembly housing (see, for example, Figures 1A-1B, 9A-9B, and 10A-10B).

[0024]

[0036] Using the exemplary embodiments shown in Figures 2, 7A–7B, and 8 for reference, the illustrated filtration system 1000 includes an embodiment of a support 500 for a coalescer filter element described with respect to Figures 1A–1B and 7C, and a hollow cylindrical coalescer filter element 600 positioned on the support such that the support passes through the hollow cylindrical coalescer filter element, with one end 601 of the hollow cylindrical coalescer filter element being received in a first end annular channel 102 and the other end 602 of the hollow cylindrical coalescer filter element being received in a second end annular channel 202.

[0025]

[0037] In a preferred embodiment, the filtration system further comprises a fluid receiving container 700 (shown as a pipe with a closed end) positioned at the outlet end of a hollow fitting that is in fluid communication with the hollow fitting. If necessary, the fluid receiving container can function as a “liquid lock”. In some embodiments, a fluid receiving tube 701 is inserted between the outlet end 212 of the hollow fitting and the fluid receiving container 700, preferably the fluid receiving tube having a first tube end 701 with a threaded outer surface 716, and the filtration system includes at least one 705, preferably two threaded nuts 705A, 705B for connecting the threaded hollow fitting to the threaded fluid receiving tube. In some embodiments, the fluid receiving tube is attached to the fluid receiving container by a retainer such as a pin or screw 726 passing through a through hole 715.

[0026]

[0038] In some embodiments, the fluid receiving container functions as a "liquid lock" as follows: The liquid receiving container is primed / pre-filled with liquid (e.g., water, see Figure 8) before startup to prevent gas from entering the bottom of the liquid lock and bypassing the coalescer filter element 600 through the inner tube.

[0027]

[0039] After pre-filling, the system then operates to allow the liquid-containing gas to pass through the system. The liquid discharged from the filter coalescer element 600 collects in the second end piece 201. The liquid is then discharged through the openings (215A, 215B, 215C, 215D) and discharged down the first tube 701, collecting in the fluid receiving container 700. Once the water has collected in the liquid lock (which already contains the pre-filled liquid), the water overflows from the top, as shown in Figure 8. This liquid is discharged to the bottom of the housing (see, for example, sump 2020 for receiving the overflow in Figure 9B).

[0028]

[0040] Using the embodiment shown in Figure 8 for reference, a method for removing undesirable contaminants and / or fluids from a gas (indicated as "green" hydrogen (obtained by electrolysis of water)) includes passing a gas containing liquid (indicated as KOH droplets) through an embodiment of a filtration system, and separating the clean gas (indicated as green hydrogen) passing upward through a fluid channel opening at a first end from undesirable contaminants and / or fluids (indicated as KOH droplets that combine along the fluid channels of a fluid flow bar and are discharged downward) through a hollow fitting and a fluid receiving tube into a fluid receiving container.

[0029]

[0041] In yet another embodiment, a coalescer assembly is provided comprising a housing having a housing inlet and a housing outlet, defining a fluid flow path from the housing inlet to the housing outlet, and having at least one filtration system within the housing that crosses the fluid flow path.

[0030]

[0042] Figures 9A and 9B illustrate a coalescer assembly 2000 comprising a housing 2050 having one or more filtration systems 1000, shown in Figure 7A according to one embodiment of the present invention, which have outlets 2001 and inlets 2002 defining a fluid flow path from inlet to outlet, and crossing the fluid flow path; Figure 9A shows a coalescer assembly 2000 configured to accept a single filtration system 1000, and Figure 9B shows a coalescer assembly configured to accept multiple filtration systems 1000 (shown as 1000A and 1000B). In these illustrated embodiments, each assembly includes a filter plate 2015 that holds the system within the housing.

[0031]

[0043] Using Figures 9B, 10A, and 10B for reference, in some embodiments of a coalescer assembly configured to accept multiple filtration systems, filtration systems 1000A, 1000B (and additional filtration systems) can be held within the housing 2050 by using first and second filter plates 2015A and 2015B, for example, by "sandwiching" a first end 100 between the first and second plates. As an example, in the embodiments shown in Figures 10A and 10B, the first end plate 2015A is shown having a through hole 2016A for receiving an end 601 of a hollow cylindrical coalescer filter element 600, and the second end plate 2015B is shown having a through hole 2016B and an inner surface having a recess 2017B for receiving a first end piece 101, and the plates 2015A and 2015B are configured to fix the first end 100 to the housing 2050.

[0032]

[0044] Various filter elements that function as coalescers, and filters containing such filter elements, can be used according to aspects of the present invention. Suitable filter elements include, for example, those configured as hollow cylindrical depth filter elements without a core.

[0033]

[0045] A filter / filter element may include additional elements, layers, or components that have different structures and / or functions, such as at least one of any one or more of pre-filtration, support, drainage, spacing, and buffering. For example, a filter may also include at least one additional element such as a mesh and / or screen.

[0034]

[0046] The coalescer assembly housing can be manufactured from any suitable rigid impermeable material, including any impermeable thermoplastic material compatible with the fluid being processed. For example, the housing can be manufactured from a metal such as stainless steel, or from a polymer.
