2y Metal Plate Structured Packing custom fabrication layer height 200mm
1. metal plate structured packing use
Structured packing provides a large surface area per unit volume, which maximizes mass transfer performance and creates a lower pressure drop than conventional distillation trays. By reducing the pressure drop, structured packing increases energy efficiency. Together with our structured packing, we use our own demister / mist eliminators to maximize column performance.
Proven performance
Around the world, we have deployed our structured packing in chemical processing, steel, gas-to- liquid (GTL), gasification and a wide variety of other applications.
2. Compare: Packed columns offer multiple benefits
Packed columns | Trayed columns |
Lower pressure drop leads to significant power savings. (Greater than 5% reduction in power is possible.) | Higher pressure drop, but shorter columns. |
High turndown capability. (Down to 40% of design capacity is possible.) | Limited turndown for efficient operation. (60-70% of design capacity is typical.) |
Enables pure argon production by distillation, therefore eliminating need for a pure hydrogen source. | Can be used for high-pressure distillation. |
3. What is the role of structured packing in high vacuum distillation column?
Distillation is a method to separate liquid mixture with high
purity by using reflux. It is a widely used liquid mixture
separation operation in industry, and is widely used in petroleum,
chemical, light industry, food, metallurgy and other departments.
Distillation operation is classified according to different
methods. According to the operation mode, it can be divided into
continuous distillation and batch distillation; according to the
composition of the mixture, it can be divided into binary
distillation and multi-component distillation; according to whether
the additives affecting the vapor-liquid equilibrium are added to
the mixture, it can be divided into ordinary distillation and
special distillation (including extractive distillation, azeotropic
distillation and salt-adding distillation); if the distillation
process is accompanied by distillation, it can be divided into two
types Chemical reaction is called reactive distillation
In the operation of packed tower, the liquid drops from top to
bottom along the structured packing surface, and the rising vapor
contacts with each other. Therefore, the packing surface is the
place for mass exchange and heat exchange.
4. Classification of distillation packing
Packed tower is a kind of gas-liquid mass transfer equipment with a
large number of packings in the tower. Packed column was used in
industrial production in the middle of the 19th century. Since
then, it has developed with plate column, forming two different
types of gas-liquid mass transfer equipment.
The body of the packed tower is a vertical cylinder with a
supporting plate at the bottom. The packing material is placed on
the support plate in a integral way. A packing pressing plate is
installed above the packing to limit the movement of the packing
with the updraft. The liquid is added from the top of the tower,
sprayed onto the packing through the liquid distributor, and flows
down the packing surface. The gas is sent from the bottom of the
tower and distributed by the gas distribution device (gas
distribution device is generally not set for small diameter tower),
then it is countercurrent with the liquid and continuously passes
through the gap of the packing layer. The gas-liquid two-phase is
in close contact with the packing surface for mass transfer. Packed
tower is a continuous contact gas-liquid mass transfer equipment,
the two-phase composition changes continuously along the tower
height. Under normal operation, the gas phase is continuous phase
and the liquid phase is dispersed phase.
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!
