Metal Corrugated-plate Packing < Mellapak >
It is formed from vertical sheets of corrugated metal with the angle of the corrugation reversed in adjacent sheets to form a open structure with inclined flow channel. Its structure can not only change the distribution of liquid, also increase the transfer efficiency.
Special features:
Pressure drop per theoretical stage 0.3-1.0mbar
Pressure drop at 70%-80% flooding about 2 mbar/m
Minimum liquid load approx. 0.2 m3/m2h
Maximum liquid load up to more than 200m3/m2h

Typical applications:
Chemical industry: Ethylbenzene/styrene, tall oil cyclohexonone, aire separation
Petrochemical industry: Quench columns
Refineries: Vacuum and atmospheric columns
Absorption: Natural gas drying
CO₂ and H₂S-absorbers and strippers
Acrylonitrile absorbers
