  Technical Principle Of Structured Packing In Distillation Column
  
  Characteristics of Structured Packing
  1
  Compared with conventional structured packing, the pressure drop of DODGEN high-efficiency structured packing in distillation column is greatly reduced under the same efficiency, and the capacity can be increased by up to 40% under the same HETP
  
  2
  As one of structured packing manufacturers, DODGEN's high-efficiency structured packings is suitable for the separation case from vacuum to medium pressure, and even for the high-pressure case in some applications;
  
  3
  Low-pressure drop for DODGEN structured packing in distillation column, the pressure drop of each theoretical plate is only 0.3 ~ 1.0 mbar under normal conditions, and only 2.0 mbar at 70% ~ 80% flooding rate;
  
  4
  DODGEN high-efficiency structured packing has good operating turndown and can be applied to working conditions with liquid load range from 0.2 m3 / m2h to 200 m3 / m2h;
  
  5
  As one of the chemical reactor manufacturers, DODGEN high-efficiency structured packing can break the capacity bottleneck of existing trays and random packing.  less

The vacuum distillation is performed at a pressure well below atmospheric pressure. The vacuum distillation unit is widely used to separate substance that decomposed, oxidized or polymerized at a temperature far below the boiling point at CDU condition.
  
  
  Application of VDU:
  1. Widely used in oil refinery field.
  
  2. PCC's VDU have a high separate efficiency.
  
  3. The heavies are further separated to obtain a product of pure purity, so as to increase product yield.
  
  
  Advantages of VDU:
  1. Advanced manufacturing method and quality
  
  2. Professional services, economical price, short delivery time
  
  3. VDU equipment are inspected under ASME standard
