125Y Metal Sheet Structured Distillation Packing 316L DN2400 * 150 mm
1. DN2400 mm * 150 mm height, 125Y metal sheet structured packing 316L.
Some of our customers use this type of structured packing as a "mist eliminator" on top of the spray tower.

3. Function of Metal Sheet Structured Distillation Packing in distillation column
Through the packing, the two-phase flow is upward and downward
convection. Gravity is the driving force of liquid flow, and
pressure difference is the driving force of gas flow. The two phase
flow is mass transfer and heat transfer through the two forms of
film surface and spray. The mass transfer and heat transfer of the
two phases in the plate column take place in the gas-liquid mixed
phase on the upper surface of the tray, on the liquid layer surface
of the downcomer and on the bubbling area caused by the mass
transfer elements.
4. factory Metal Sheet Structured Distillation Packing advantage
The advantages of corrugated packing are compact structure and large specific surface area. The specific surface area can be adjusted by the shape of corrugated structure. There are 125, 150, 250, 350, 500, 700 and so on. The two adjacent plates of packing are perpendicular to each other, which makes the upward flow change direction and the falling liquid redistribute continuously, so the mass transfer efficiency is high. The regular arrangement of packing reduces the flow resistance and improves the treatment capacity. The disadvantage of corrugated packing is that it is not suitable for processing materials with high viscosity, easy polymerization or suspended solids. In addition, it is difficult to load, unload and clean the packing, and the cost is also high.
According to the material structure, corrugated packing can be divided into mesh corrugated packing and plate corrugated packing, and its material can be divided into metal, plastic and ceramic.
5. Loading and shipping of Metal Sheet Structured Distillation Packing
every year we manufacture and supply hundreds of cubic meters of metal structured packing in different models. There are many popular types and materials for option. Custom order is welcome, too! We are happy to help with what you need!
