Audited Supplier Since the first generation of structured packing arose in the early 1940s, It has undergone constant upgrades and modifications in several decades. Open honeycomb structure with inclined flow channels had provided a relatively high surface area but with very low resistance to gas flow. 452 Plus Structured packing's distinguishing features is curve channel of packing unit. This design has not only ensue air flow's smooth and steady change in innser structured packing bed, but also reduced the pressure drop and shear force, and overcome the flooding phenomenon at the joint of the packing.
Unlike random packing, which relies on a collection of loosely packed particles.Metal structured packing provides a well-defined surface area and flow path for the liquid and gas phases.Metal Structured packing consists of a series of specifically designed metal sheets or grids that are assembled in a structured manner to form a packing element. This structured arrangement enhances mass transfer efficiency and promotes uniform distribution of the fluids.
Due to those metal sheet has many small gill surface pitting, extending the vapor-liquid surface of the lag in filling time steroid that tower more fully vapor-liquid exchange and improve the separation efficiency.
Feature:
High efficiency: The precise design of the structured packing, with its specific surface area, promotes effective mass transfer between the liquid and gas phases, resulting in improved separation efficiency.
Low pressure drop: The structured arrangement of the packing promotes uniform distribution of the fluid, reducing pressure drop across the column. This can lead to energy savings and lower operating costs.
High capacity: Metal structured packing can handle high liquid and gas loads, making it suitable for applications requiring high throughput and separation efficiency.
Corrosion resistance: Metal structured packing is often made from corrosion-resistant materials such as stainless steel or special alloys, making it suitable for processes involving corrosive media.
Longevity: Metal structured packing is durable and has a long service life, making it a cost-effective option in the long run.

1:All packing must be lie in the carrying platform(such as wooden plate). Be trapped by rope is forbidden.
2:The lifting sequence must start gradually from the perimeter inwards based on the drawings.Strictly prohibited to the deformed packing,debris in the packing module during lifting. As soon as the similar phenomenon happened, On-site staffs should be shaped and treated promptly.
3:The packing tied with brown rope is fed from the manhole or the top of the tower in the order of the assembly diagram.
4:The packing is assembled from the top of the support and marked at a certain distance (e.g. 1 or 2 meters) in order to keep track of the height tolerance of the packing layer.As soon as damage to the tower wall is detected, stop and notify the relevant personnel to deal with it in a timely manner.
5:The first layer of Metal structured packing 's installation direction is refer to assemble diagram. As for the rest of Metal Structured packing, each layer is staggered at 90 degrees to the next adjacent layer. Each packing module will be lied by the drawing sequence.Perimeter Packing Modules must be tightly fitted to the tower wall without any gaps. Other Packing modules has not any gap. After installation of each layer, Using filling tool to adjust each module's the looseness and tightness ensure all modules' Loosen and tighten evenly. After then, remove the wire and packing tape and tread lightly with your feet. No clutter is allowed in the tower
6:Each layer of packing is assembled from the wall towards the center of the tower. If a large gap in the last piece of the installation's happened, we can use one piece or many piece to be filled in the gap. Strictly forbidden to kick or poke the packing.
7:The installer should hold the packing gently to minimize damage to the packing during installation.
8:In the case of special reason for not being able to install,Emergency treatment in accordance with the advice of our on-site instructors
9:If the tower roundness bias is very big(indirectly influence Module installation), inform our on-site instructor and and enter withdrawal and cut corrugated monoliths with his approval.No withdrawal and cutting without prior consent.
10:After each layer of packing is installed, it must be approved by our on-site instructor before the next tray of packing is installed.
Application:
1:Metal structured packing used in vacuum and atmospheric crude oil fractionators, FCC main fractionators and TEG contactors.
2:Metal Structured packing used in the separation of mono-, di- and triethanolamine, conducted under vacuum
3:Metal Structured packing used in Tall oil fractionation, the process of separating fatty acids from rosin acids and pitch obtained as a by-product of the Kraft process of wood pulp manufacture,
4:Metal Structured packing used in the manufacture of styrene monomer and the dehydration of glycol in natural gas processing
