Random PackingSaddles, Ballast & Nutter Rings Coalescing & Filter Media

DESCRIPTION Random packing has unique features which are based upon fundamental principles of fluid flow. A look at each feature: Form provides multiple circular crimped strips to encourage liquid surface renewal. Ceramic Saddles

Perforated central trough enhances lateral liquid spreading and effectively wets the outside surface facing vapor flow Flanged edges and central rib promote lateral liquid spreading around the main element. Heavily ribbed main element for a high strength-to-weight ratio.

Ballast Rings

A pair of tapered slots and hoops provides maximum randomness with minimal nesting.

Nutter Rings

FORMULA 

FEATURES Efficiency enhanced by lateral liquid spreading and surface film renewal.

Determines the number of cubic feet needed. V= π * r2 * H

Superior surface utilization in mass and heat transfer, allowing shorter packed bed heights. Strength-to-weight ratio sufficient to withstand weight of 50-ft. bed height. Maximum piece-to-piece contact with minimal nesting. Lower pressure drop and greater usable capacity enable use of smaller-diameter columns Reproducible performance assured through uniform randomness.

PERFORMAX Coalescer Coalescing & Filter Media PERFORMAX Coalescers DESCRIPTION Natco revolutionized oil and water separation with the development of the PERFORMAX matrix plate. This coalescing media accelerates gravity separation of oil from water and water from oil with remarkable efficiency. It is useful in heated process equipment as well as in ambient separation systems like free-water knockouts. It handles a wide variety of oil and water dispersions in all ranges of API oil gravities.

Large Volumes in Small Vessels The horizontal coalescer uses an inlet momentum absorber to slow the velocity and distribute the flow of the incoming stream. Then the oil and water mixture flows into the PERFORMAX matrix plate section where the inclined channels accelerate coalescence. (See Figures 1 & 2). Separation efficiency improves dramatically because PERFORMAX technology causes the oil droplets to coalesce and rise much more rapidly than smaller droplets in conventional coalescers. (See figures 3 & 4). As a result, the PERFORMAX coalescer handles higher flow rates through smaller vessels and gets better results.

PERFORMAX Coalescer

Coalescing

Why should you consider PERFORMAX matrix plates? Achieves excellent water quality and 98% removal of oil particulates attainable with proper chemical treatment. Improves gas quality with lower oil entrainment and eliminates the need for a supplement mist extractor. Lowers BS&W content with higher quality of discharged oil it allows greater treater efficiency and lower fuel requirements. Reduce chemical costs with lower chemical dosages which improves performance and reduces chemical costs as much as 50%. Consistent operation under widely variable conditions, it absorbs fluctuating flow rates, varying solids contamination and oil and water mixtures to minimize the effects of normal day to day upsets. Reduce space requirements because the PERFORMAX system uses a single, often smaller vessel with a higher flow rate capacity to achieve better separation efficiency. The horizontal vessel minimizes head room requirements. Lowers operating costs since no power is required for the actual separation process. No pumps required so the system is totally inline with no head loss in the operation. Simple installation above or below ground with hook-up to the incoming flow to the water effluent line and oil effluent lines. High reliability because there are no moving parts and the media itself is easily removable for routine maintenance and cleaning. ASME Code Construction is a Natco standard. Resists plugging because the open matrix design minimizes plugging problems often encountered with other types of coalescing systems. Ideal for retro fit because PERFORMAX plate sections retrofit easily into existing coalesces, free water knockouts and skim tanks to boost their capacities and efficiencies.

 Vane Pak & Mistex Coalesing & Filter Media

Vane Pak DESCRIPTION The Vane Pak Mist Eliminator is designed to remove entrained liquid droplets from high velocity gas streams. The rugged construction and open blade spacing can be used in diverse applications. The non-welded, bolt and spacer construction adds an extra edge to corrosion resistance. All the vane paks are designed to meet a wide range of process requirements Vertical radial flow vane paks are utilized for high gas/oil ratios, any oil gravity and very high gas flow rates. The separation mechanism is impingement and coalescence. They are used in vertical separators Vertical radial flow vane paks allow higher gas flows through the separator. The radial vane passageways diverge to give better turndown performance

Vertical radial flow vane paks can be retrofitted to existing separators.

Mistex Pad DESCRIPTION The Mistex Pads are designed for the separation of mist and small liquid droplets from gas or a vapor stream. The theory on the mistex pad is that the liquid particles collide with the wire mesh and coalesce into droplets. Gravity will then cause the droplets to fall through the mesh pad and collect in the vessel. Dry gas will go through the downstream side of the wire mesh while the liquid is removed from the vessel through a dump valve. The knitted wire mesh is rolled and available in different sizes and shapes. The material is a 9# density and is available in 4” and 6” thicknesses and the grade of the material is 316 Stainless Steel. Mistex Pad
