SS304 SS316 metal structured packing for air liquid filter and distillation tower
1. factory of 250Y structured packing.
Super Packing Mall Metal Structured Packing is a general type of packing, which is composed of several vertically arranged reticulated corrugated plates. Instead of welding, the metal wire gauze structured packings are fixed to the wall with nails or rings. Its structure can not only change the distribution of liquid, but also improve the transfer efficiency.
2.The role of structured packing in high vacuum distillation column
The main advantage of metal wire gauze structured packings is that even under very small liquid load, the separation efficiency is very high, the pressure is reduced, and the liquid retention is small, so it is very suitable for distillation of heat sensitive products. (including extractive distillation, azeotropic distillation and salt distillation) according to whether the additive in the mixture is added to affect the vapor-liquid balance. If the distillation process is accompanied by distillation, there are two types of chemical reactions called reactive distillation.
3. factory structured packing types:
Below are the main types we usually make. Each type has two styles, different in the wave clination angle to the axis, 30 degrees (X style) and 45 degrees (Y style). For example, 250Y structured packing, each wave has a 45 degrees angle to the axis, and the neighboring plates' waves are vertical to each other. We can also help make other types such as 450, 252, 452, etc. as per customer request.
| Type | Surface area | Void fraction | Wave height | Nt | ΔP | Max.F-factor |
| m2/m3 | % | mm | m-1 | Pa/m | m/s.(kg/m3)0.5 | |
| 125 | 125 | 98 | 25.4 | 1-2 | 150 | 3 |
| 250 | 250 | 97 | 12.5 | 2-3 | 200 | 2.6 |
| 350 | 350 | 94 | 9 | 2.0-2.5 | 300 | 2 |
| 500 | 500 | 92 | 6.3 | 4-5 | 400 | 1.8 |
| 700 | 700 | 85 | 4.5 | 5-7 | 650 | 1.6 |
4.Application
Fine chemical, flavours factory, isomer separation. The separation of thermally sensitive materials, testing tower and the improvement of tower.
5. factory structured packing cases
They are widely used in private refineries and some pilot projects. I was lucky because he knew a lot about structured packaging and came up with the type he wanted. To be honest, while I know the basic characteristics of each type of packaging and can do some simple calculations on it, it is far from enough to provide professional advice that is appropriate for the entire system.
structured packing refers to a ranges of specially designed materials for use in absorption and distillation columns and chemical reactors in order to improve separation.
structured packing typically consists of thin corrugated metal plates or gauzes arranged in a way that they force fluids to take complicated paths through the column, thereby creating a large surface area for contact between different phrases . it provides high capacity, high efficiency and lower pressure drop than any random packings and most trays. Because of the capillary effect, the wire gauze material provides an extremelly wettable surface, resulting in excellent mass transfer efficiency, particularly at very low liquid rates.
