1. Hualai 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.
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.
In Hualai, 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!
