OEM DN350mm BX500 Wire Mesh Tower Packing

Product Specification

DN350 - 200mm Tower Packing BX500 wire mesh type in carton

Applications of metal structured packing:

1. In ethylbenzene/styrene separation, after a sieve tray column was revamped with corrugated orifice packing. Under the same overhead operating pressure, the pressure of the reactor decreased from 32000 Pa (320 mbar) to 13500 Pa (135 mbar), and the pressure drop decreased from 24700 Pa (247 mbar) to 6200 Pa (62 mbar), the temperature of the reactor decreased from 104 to 83 degrees, and the reflux ratio decreased from 9 to 6.5. The treatment capacity increased from 16500 kg/h to 28300 kg/h (increased by 70%), the degree of polymerization decreased from 0.5% to 0.1%, and the steam required per ton of product decreased by 25%. The remarkable effect of increasing production and saving energy was achieved.
2. A 6500 t/a atmospheric distillation unit was revamped with orifice corrugated packing for propylene oxide separation.
3. Revamping of Lubricating Oil Vacuum Fractionation Tower, Replacing Tower Plate with Orifice Plate Corrugated Packing and Cascade Mini Ring.
4. Gas oil vacuum distillation column uses corrugated orifice plate structured packing instead of random packing.
5. Replacing original plate tray with corrugated packing of orifice plate in ethylene water quenching tower.
6. Ethylene/ethane high pressure distillation column was reformed with corrugated packing of orifice plate.
7. Cyclohexanone / Cyclohexanol Separation Column with Regular Packing with Corrugated Pore Plate
8. DMT Separation Tower, uses Corrugated Plate structured packing instead of Random Packing

Structure of packed tower using BX 500 wire mesh type packing

The packed tower is a continuous contact gas-liquid mass transfer equipment, which is composed of tower shell, packing, tower internals, gas-liquid inlet and outlet pipe fittings, etc.
The packing is the gas-liquid mass transfer element in packed tower, which determines the gas-liquid flow and contact transfer mode in the tower. Therefore, the material, structure and size of packing all affect the effective surface area and mass transfer coefficient of mass transfer, and determine the adaptability, effectiveness and economy of mass transfer process. There is a filler support under the filler to bear the weight of the filler. There is a liquid distributor above the packing, whose function is to evenly distribute the inlet liquid on the whole cross-section of the packing and keep a good initial distribution. Due to the wall effect of liquid in the packing layer and the formation of channel flow, the liquid redistributor should be set in the middle of the high packing layer to make the liquid redistribute evenly.
When the thin layer of high porosity packing is placed in the large diameter tower, the gas flow distribution on the cross section of the tower is not uniform, which affects the mass transfer efficiency of the packing. At this time, the inlet gas distributor should be set to make the high-speed gas flow in the feed pipe evenly distributed on the cross-sectional area of the tower.
In order to prevent the high-speed air from blowing or blowing up the packing layer, the top of the packing layer is provided with a packing pressing ring or a bed layer limiter. In addition, a liquid collector is required to lead out the side line.
