Plastic random packing

Plastic random packing is made from heat resistant and chemical corrosion resistant plastics, including polyethylene (PE), polypropylene (PP), reinforced polypropylene (RPP), polyvinyl chloride (PVC), chloridized polyvinyl chloride (CPVC) and polyvinylidene fluoride (PVDF). It has features such as high free volume, low pressure drop, low mass-transfer unit height, high flooding point, uniform gas-liquid contact, small specific gravity, high mass transfer efficiency and so on, and the application temperature in media ranges from 60℃to 150℃. For these reasons it is widely used in the packing towers in petroleum industry, chemical industry, alkali-Chloride industry, coal gas industry and environmental protection, etc.

61Snowflake

Snowflake Performance:

1)Lowest Pressure Drop and Highest Capacity

2)Lowest pressure drop of any Koch-Glitsch plastic packing.

3)Low pressure drop and high capacity allows smaller column diameter and blower sizes in new installations.

4)Low pressure drop minimizes process back-pressure from scrubbers.

5)Low pressure drop substantially reduces energy consumption.

Item	Void Fraction %	Bulk Weight g/m3
Index	97	51

Snowflake Applications:

1)Chlorine and Bromine production plants

2)Emergency scrubbers

3)Air and water coolers in air separation plants

4)HCl absorption in various processes

5)Environmental scrubbers and strippers

Snowflake High Efficiency and Capacity

1)High capacity for high liquid rates allows reduction in column diameter in new installations.

2)Exceptional efficiency at low liquid rates improves separation performance and allows reduction in column height in new installations.

 

 

62Teller Rosette

It was designed by Tell A. J in 1956, so it called Teller Rosette Ring. The packing liked ellipse is consist of many enlaced cirques. For high liquid load in lacuna of packing, so prolong time of gas-liquid contact, enhance the efficiency to transfer, based on these of characteristics of big voidage, low pressure drop, the sufficiency gas-liquid contact, low weight , high efficiency of transfer, it is widely available in the washing, refining tower.

63Plastic Saddles

The middle part of this packing is the arc liquid channer so as to the flow air along with arc liquid channel. As big voidage, low pressure drop, low weight of mass transfer unit, high flood point, abundant of gas-liquid contact, the application temperature ranges in 60℃ to 150℃, it is very widely adopted in packing tower of Alkali-chloride industry petroleum industry, coal gas industry chemical industry, environment industry.

 

 

 

64Plastic Pall Ring

It has the characteristic of low pressure drop, large void space, large flux, high efficiency, low energy consumption etc., Further more excellent distribution in tower packing, it is widely apply in the separation and absorption process, device of reducing pressure. The system of deviating sulfur. Isolation of Ethylbenzene Toluene, Trimethylpentane etc.
