Hualai OEM service CY 700 metal wire mesh structured packing data sheet

Materials of Construction

The most common material used for Hualai structured column packing is SS 304L and SS 316L. However Hualai manufactures this solely based on our customers’ requirements and can also be made from other materials based on special requests. Other materials like Titanium, duplex 2205, copper, etc. are also no problem with us.

Uniform Liquid Distribution

In order to achieve even liquid distribution over the packing it is a must to have a good liquid distributor to maximize the interaction of the liquid and vapor. However if the packing height exceeds 3 meters we recommend using an intermediate liquid re-distributor as well for even flow.

Hualai wire gauze structured packing is the preferred packing in distillation service for deep vacuum and low liquid rate applications. The characteristic of lowest pressure drop per theoretical stage makes wire gauze packing the preferred device for processing specialty chemicals, pharmaceuticals and temperature-sensitive materials.

Wire gauze packing is generally used in small to medium diameter columns to achieve the maximum number of theoretical stages in the minimum column height. Because of the capillary effect, the wire mesh material provides an extremely wettable surface resulting in excellent mass transfer efficiency particularly at very low liquid rates.

Projects applying wire mesh structured packing

• 700Y wire mesh structured packing is used in irisone refinery.
• Narrow fraction color ink solvent oil separation, about 50 theoretical plates are needed, uses 7 m 700Y corrugated wire mesh packing.
• Octanol and octanone are separated by 700Y corrugated wire mesh packing instead of Raschig Ring.
• Fusel oil recovery distillation column, using 700Y wire mesh packing instead of ceramic Raschig ring.
• Separation of Methanol from Edible Alcohol Solution.
• Propylene oxide distillation column.

• Methanol refining deetherification tower using 5.6 m 700Y wire mesh packing instead of floating valve tower with 18 m high and 60 plates.
