ALPHA PACK

High performance random packing provides the
lowest possible pressure drop
and high efficiency.

Performance:
• Lowest Pressure Drop and Highest Capacity
• Lowest pressure drop of any plastic packing.
• Low pressure drop and high capacity allows smaller column diameter and blower sizes in new installations.
• Low pressure drop minimizes process back-pressure from scrubbers.
• Low pressure drop substantially reduces energy consumption.

High Efficiency and Capacity
•Exceptional efficiency at low liquid rates improves separation performance and allows reduction in column height in new installations.
•High capacity for high liquid rates allows reduction in column diameter in new installations.

Application:
• Chlorine and Bromine production plants
• HCl absorption in various processes
• Emergency scrubbers
• Environmental scrubbers and strippers
• Air and water coolers in air separation plants

 

 

Material available:
Polypropylene, Glass Filled Polypropylene, Low Density Polyethylene, High Density Polyethylene, PVC, CPVC, Kynar (PVDF), Halar (E-CTFE), Tefzel (ETFE), Glass Filled ETFE, PFA

PLASTIC PALL RINGS

Pall Ring packing is an economical and versatile
industry standard with well-known performance characteristics.

•Good capacity and low pressure drop
•Higher liquid hold-up and residence time
•Versatile standard packing
•High mechanical strength

Performance:

Good Capacity and Low Pressure Drop
•Higher capacity and lower pressure drop than ceramic packing.
•Multiple sizes provide ability to optimize capacity and efficiency based on application requirements.
Higher Liquid Hold-up and Residence Time
•Relatively high liquid hold-up allows good absorption efficiency with slow chemical reaction.
Versatile Standard Packing
•Lower sensitivity to liquid and vapor distribution quality allows use with conventional liquid distributors.
High Mechanical Strength
•Ring and spoke construction provides high mechanical strength, which allows use in deep beds.

Application:
• Absorption, scrubbing, and stripping services
• Versatile alternative to metal Pall rings

Material available:
Materials: Polypropylene, Glass Filled Polypropylene, Low Density Polyethylene, High Density Polyethylene, PVC, CPVC, Kynar (PVDF), Halar (E-CTFE), Tefzel (ETFE), Glass Filled ETFE, PFA

PLASTIC SADDLES

Plastic Saddles are a versatile and economical industry standard with well-known performance characteristics.

• Good capacity and low pressure drop
• Higher liquid hold-up and residence time
• Versatile standard packing

 

Performance:
Good Capacity and Low Pressure Drop
Higher capacity and lower pressure drop than ceramic saddles. Multiple sizes provide ability to optimize capacity and efficiency based on application requirements.
Higher Liquid Hold-up and Residence Time
Relatively high liquid hold-up allows good absorption efficiency with slow chemical reaction.
Versatile Standard Packing
Lower sensitivity to liquid and vapor distribution quality allows use with conventional liquid distributors.

Application:
Absorption, scrubbing, and stripping services
Pulp and paper service, such as bleach plant absorbers
Versatile alternative to ceramic saddles

 

Material available:
Polypropylene, Glass Filled Polypropylene, Low Density Polyethylene, High Density Polyethylene, PVC, CPVC, Kynar (PVDF), Halar (E-CTFE), Tefzel (ETFE), Glass Filled ETFE, PFA
