Columns: Structured Packing

Corrugated metal plates packing are made up of metal plates with thickness more than 0.1mm. The normal types are 125X/Y, 200X/Y, 250X/Y, 300X/Y, 350X/Y, 500X/Y and 700X/Y.

The prefered materials are AISI 410S (=DIN 1.4000), AISI 304(L) (=DIN 1.4301/1.4306) and AISI 316(L) (=DIN 1.4401/1.4404).

The wall wiper band is always installed at our packing, so it will not be forgotten during installation and installation is much easier and needs less time!

Special features:

Relatively high number of theoretical stages per meter
Low pressure drop per theoretical stage 0.3~1.0kpa
Liquid load 0.2~200m3/m2·h

Preferred applications:

Vacuum to overpressure
For large-scale production
Raising throughput on existing columns
In conjunction with heat pumps

The impulse sections at the end of each packing layer decrease the local pressure drop at this point. This eliminates the sudden change in flow direction of the liquid and vapour phases at the packing layer interface.
The impulse section in the middle of each layer gives an extra turbulence and a better liquid flow.

With this patented packing the capacity of columns can be enhanced appr. 30%.

The efficiency is about 5% higher than traditional corrugated structured packing.

Preffered Application

• Vacuum to overpressure
• Large scale production
• Increasing throughput on existing packed columns

Wire gauze packing are in successful use for more than 40 years. The special wire gauze is designed to provide the best performance and pressure drop per theoretical stage in the vacuum range from 1 mbar. Separation of temperature sensitive substances can be done like with no other packing. Columns up to 6 meter in diameter have been succesful equiped.

Special features

• Very high NTSM
• Very low pressure drop per theoretical stage
• Minimum liquid load (< 0,1 m³/m²h) is possible
• Small hold-up
