AMACS Process Tower Internals products

Mist elimination, or the removal of entrained liquid droplets from a vapor stream, is one of the most commonly encountered processes regardless of unit operation. Mesh mist eliminators are fabricated as multiple layers of knitted wire mesh, wherein the crimped strips are stacked to form a pad with a specific density and thickness. Rigidity is provided by a high open area frame, usually metal, consisting of a grid on each side and rods passing through the mesh

Our patented MistFix® Insertion Mist Eliminator was developed specifically for retrofit applications where the existing vessel had no mist eliminator support and/or no internal access. We found that the oil and gas industry had a large number of vertical gas Knock Out Drums that were designed to run at relatively low gas rates and had no internals to promote mist elimination. Over time, plant capacities were increased feeding more gas into the drum than was originally considered.

The greatest single improvement in random packing came with the introduction of “windows” and “finger” to the Raschig Ring packing.  By opening up the Raschig Ring, by punching tabs in the wall of the ring to created internal drip points within the ring, both the capacity and efficiency of the random packing increased by 50-80% over the Raschig Ring Packing.  The Pall Ring is characterized by having the same height as its diameter.  This type of packing is used extensively in absorption, stripping and distillation services.  ASRP High Performance Packing can replace it for better efficiency and capacity in the same bed height and column diameter.

Accuflow™ Inlet Diffuser (Vane type inlet device) is a feed inlet device placed at an inlet nozzle for process streams with 2-phase (gas/liquid) entering a separator and/or scrubber. Primarily it reduces the inlet momentum of incoming stream and provides bulk gas/liquid separation while assuring a much better and uniform gas distribution across the vessel cross-section area, which is a key element for phase separation. In addition to this, it offers many others benefits that improve the overall separator/scrubber performance, including but not limited to, preventing further shattering of liquid droplets, and preventing re-entrainment of liquid from liquid surface.

The next generation of random packing was accomplished with the development low aspect ratio packing. The “low aspect ratio” refers to the height of the packing being less than the nominal diameter of the packing. The low aspect ratio packing promotes a better or “less random” fill of the packed bed.  The packing settles in a manner that orients more of the flat surfaces parallel to vapor and liquid traffic than perpendicular to flow.  This orientation increases capacity while maintaining an effective surface area for vapor/liquid contact.  Applications include uses in atmospheric and high-pressure distillation, demethanizers, deethanizers, acid gas removal, quench towers, and main fractionators.  ASRP Packing is the mechanical equivalent of the Intalox Metal Tower Packing (IMTP®).  The AMACS Saddle Ring Packing offers higher capacity and efficiency that the comparable size Pall Ring packing.

AMACS Woven Structured Packing is a high efficiency, corrugated-type packing constructed with a wire gauze material. This product is typically used for fine chemical distillation when fouling is not a concern. Its applications is often vacuum distillations where the liquid rates are extremely low and minimizing pressure drop is critical. The closely woven wires spread the low liquid flow through capillary action. This arrangement of corrugated gauze material provides the best value when measured on the basis of pressure drop per theoretical stage.

As important as the vapor/liquid contacting device is, the proper distribution of the vapor and liquid to the device is just as important.  Without the proper distribution of vapor and liquid to the distillation trays or random & structured packing, the maximum capacity and efficiency of the device cannot be achieved.  And there are just about as many different distribution devices as there are mass transfer devices.  Each one has its advantages and limitations depending on the process conditions and objectives. 

MAXSWIRL Inlet Cyclone assembly comprises one or more vertical inlet cyclone tubes. Gas-liquid separation takes place within the tube(s) as the fluids pass downward through a static swirl and are brought into a swirling motion. The centrifugal forces generated by the swirling flow, pushes the incoming liquid to the cyclone wall. The gas reverses the flow direction and exits from the top of the tube, while the liquids flow down along the cyclone wall and ultimately exit from the bottom.
