The best media for gas/liquid contacting.Mott porous metal. There’s no better media for producingminiature, slow-moving bubbles – the best method ofachieving high-efficiency gas/liquid contacting. Fordecades, Mott porous metal spargers have been the fast,reliable, cost-effective choice for gas/liquid contacting in allsorts of industries. Here are a few reasons why:Small bubbles transfer gases faster, more efficiently.Mott spargers introduce gases into liquids throughthousands of tiny pores, creating bubbles far smaller andmore numerous than with drilled pipe and other spargingmethods. The result is greater gas/liquid contact area,which reduces the time and volume required to dissolvegas into liquid.With thousands of pores over the surface, large volumesof gas can be passed with very high specific area.For example, with equal volumes of gas, 1mm bubbleswould have 6.35 times more gas/liquid contact surfacearea than 6.35mm (1/4") bubbles.All-metal construction lasts for years.Mott spargers are constructed entirely of metal, to providelong-lasting operation even in the midst of temperaturesas high as 1450°F under oxidizing conditions. And for inertand corrosive media, Mott offers a wide range of materialsincluding 316L stainless steel (standard), Nickel 200,Monel ® 400, Inconel ® 600, Hastelloy ® C-22/C-276/Xand Alloy 20.Simple, cost-effective, easy-to-install.Mott spargers typically consist of a porous metal element,a threaded fitting and, in longer units, a reinforcement rod.The design is simple, without moving parts. Installationis easy, and requires no special tools. From single elementsto manifolded systems, Mott spargers are among thesimplest, most affordable and most efficient gas/liquidcontacting solutions available anywhere.All sizes and configurations.Mott spargers are designed, manufactured and finishedat Mott. So if you need a non-standard size, or a specialfitting, Mott has the capability to accommodate yourrequest.DISSOLVED OXYGEN PPM10987654321Mott GasSaverOxygen Stripping - N 2 Stripping GasGasSaver ® Performance - N 2 RequirementsDrilled Pipe Sparger ComparisonInitial O 2 Concentration - 8PPMDrilled Pipe Sparger00 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20N 2 (pounds/1000 gallons of liquid)Oxygen stripping, using nitrogen.

Static spargers.Tank spargers.In-tank sparging applications can be for batch orcontinuous operation, with or without agitation within thevessel. Mott sparging technology provides performanceprovendesigns to assure optimum process operation.Mott spargers are arranged in the bottoms of tanks andvessels in a variety of ways. For smaller tanks, one spargerwill often suffice. For larger tanks, several Mott spargersmay be manifolded together using a linear or radialpattern to achieve optimal gas diffusion.Mott offers a wide variety of standard tank sparger elementsand manifolded assemblies to accommodate mostapplications. Custom designs are also available by request.Typical tank sparger arrangementsSparger elements.Type AHex NippleFrom 0.375" up to 2.5" diameterType CDReinforced 1.5", 2" and 2.5"diameterType GPlain TubeFrom 0.375" up to 2.5" diameterType 6400Reducer MountedFrom 0.375” up to 1" diameterType 850Reducer MountedImpingement TubeFrom 0.375" up to 1" diameterType RTrapped Flange MountedFrom 0.375" up to 2.5" diameterSingle ElementType 6400 ElementSide MountedMultiple ElementsType 6400 ElementsSide MountedType RFFull Flange MountedFrom 0.375" up to 2.5" diameterType RSSanitary Flange MountedFrom 0.375" up to 2.5" diameterSingle ElementType CD ElementDip Leg MountedManifolded (Cross)Type A ElementsDip Leg MountedSingle ElementType CD ElementFlanged Side MountedCross TankType A ElementsFlanged Side MountedElements larger than 2.5" diameter are availableon special order.Support Studs or Centering Rods on the closed end ofelements available if required.Reinforced elements are recommended for agitatedvessels.Standard materials are 316L stainless steelporous media with 316 stainless steel hardware.Other materials are available on special order.WWW.TEESING.COM | TEL +31 70 413 07 50

Dynamic pipeline spargers.Non-intrusive (in-line) sparging.Mott GasSavers ® are unique, high-efficiency gas/liquidcontacting devices for in-line mounting in process systems.As liquid moves through the inside of a porousmetal tube, gas is introduced into the annulus – theMott Laboratory GasSaversAll Welded Constructionarea between the porous tube wall and the outerGasSaver housing. The gas moves through the porousmetal into the liquid, creating bubbles which are quicklysheared. This action results in very fine bubbles, ideal forgas introduction as well as absorption.All Welded GasSaver ®Industrial GasSaver ®Mott Industrial GasSaversMott Sanitary GasSaversSanitary GasSaver ®Side stream sparging.In large installations where access to the main pipeline isdifficult, a “side stream” GasSaver installation often provesto be the best configuration for optimum process performance.Units can be valved to allow maintenance withoutinterfering with the main pipeline.WWW.TEESING.COM | TEL +31 70 413 07 50

Intrusive (tangential) sparging.A sparging element located in a pipeline constitutes anintrusive sparger. The element can be mounted in anelbow or tee in the pipeline. Liquid passes through theannulus between the pipeline and the element. Gasexits from the outside of the element where bubblesare sheared by the liquid, resulting in fine bubbles forsuperior performance.Intrusive Pipeline SpargersSeries 8501Pipe Mounted Intrusive Sparger ElementsElbow MountedTee MountedSide MountedSide Angle MountedSanitary Tee MountedWWW.TEESING.COM | TEL +31 70 413 07 50
