1. Function of 350Y structured packing in distillation column

Through the packing, the two-phase flow is upward and downward convection. Gravity is the driving force of liquid flow, and pressure difference is the driving force of gas flow. The two phase flow is mass transfer and heat transfer through the two forms of film surface and spray. The mass transfer and heat transfer of the two phases in the plate column take place in the gas-liquid mixed phase on the upper surface of the tray, on the liquid layer surface of the downcomer and on the bubbling area caused by the mass transfer elements.

2. 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.

3. Hualai structured packing products list (part):

350Y corrugated perforated packing is one main type of Hualai structured packings made of metal sheets. The punched and grooved surface structure provides ideal contact between gas and liquid flow. 

Hualai has years of engineering experience with a variety of structured column packings in different industrial applications. Moreover, we have frequent co-operations with famous universities and technical engineering companies in China.

Resulting from these valuable assets, we have produced range of structured packings suitable for engineering systems that provide optimum column performance. As a general rule, new columns should be sized to operate at 80% of capacity at the maximum design loading.

For improved performance in new and existing towers. The uniform arrangement of structured packing provides many advantages compared to random packing or fractionation trays. Using structured packing can provide:

Higher capacity

Reduced liquid hold-up

Excellent liquid spreading characteristics

Lower pressure drop through the column

Higher efficiency in the same tower height
