Perforated Plate Packings – Perforated Surface for Mass Transfer Efficiency
Metal perforated plate corrugated packing is made from perforated plate with channel corrugation on surface, and remains structure feature of metal wire gauze packing. It strengthens uniform liquid distribution and surface wetting ability, which increases mass transfer efficiency. The unit height is 50-200 mm per coil, and the packing is prepared in blocks when diameter is larger than 1.5 m.
It is formed from vertical sheets of corrugated metal with the angle of the corrugation reversed in adjacent sheets to form an open structure with inclined flow channel. Its structure can not only change the distribution of liquid, but also increase the transfer efficiency.
Metal perforated plate corrugated packing has uniform liquid distribution and surface wetting ability.
Metal perforated plate corrugated packing has the structure of high transfer efficiency.
Mellapak has strong resistant to fouling.
Mellapak can be used in natural gas drying.

- Strong resistance to fouling.
- Low resistance, even gas and liquid distribution.
- High efficiency, large flow rate and unremarkable magnifying effects.
- It's applied to negative pressure, normal pressure and pressurization operation.
Metal perforated plate corrugated packing is widely used in unit operations like rectification, absorption and extraction.
According to packing types, the applicable minimal tower diameter is 80-200 mm while maximal tower diameter reaches 13 m, liquid spray density ranges from 0.2 to 200 m3/(m2•h) and pressure ranges from vacuum to high pressure. For these reasons, it is a type of all-purpose efficient structured packing suitable for chemical industry, chemical fertilizer industry, oil refining, petrochemical industry and natural gas industry.
