Improved Pall Ring

AMISTCO AIPR tower packing is basically a more finely tuned and better performing Pall ring. This AMISTCO improved Pall ring design allows greater capacity, lower pressure drop, and even and thorough gas and liquid bed distribution. Although similar in outward appearance to Pall rings, AIPR packing offers more interior surface area due to more twists and bends in the internal geometry. The AIPR geometric configuration creates greater gas/ liquid contacting and 25 to 30% more transfer points per cubic foot than standard Pall ring designs. Although more contacting takes place, results show 10% or greater capacity advantage over standard Pall rings in pressure drop vs. gas rate tests. The AIPR provides superior distribution and avoids channeling towards the vessel walls. AMISTCO AIPR Tower packing can improve performance in a wide range of applications including:

• Gas dehydration
• Demethanizing
• Tall oil fractionating
• CO2 removal
• High vacuum distillation
• Vacuum crude stills
• H2S contacting
• Liquid/liquid contacting

The AMISTCO AIPR tower packing high strength geometry makes them well suited to deep beds. AIPR tower packings are available in a wide range of metal and alloy materials. For availability and lead times consult the factory. AMISTCO Separation Products, Inc. manufactures a full line of tower internals, mist eliminators and other components critical to effective mass transfer and separation.
