DODGEN
Structured Packing
DODGEN provides a complete portfolio of structured packing solutions designed for a wide range of operating conditions, including high efficiency, low pressure drop, strong resistance to fouling, and heat-sensitive applications.
Structured Packing Equipment Introduction
Corrugated structured packing is one of the most widely applied separation internals in industrial mass transfer operations.
It is suitable for the full operating pressure range from vacuum to medium and high pressure.
Based on over 50 years of industrial application experience, DODGEN has carried out in-depth optimization of the packing geometry and developed the next-generation DG Plus™ series, which significantly reduces pressure drop while maintaining equivalent separation efficiency.
For conventional distillation as well as demanding services involving heat-sensitive media or fouling tendencies, DODGEN provides structured packing configurations tailored to specific process requirements and column constraints.
DODGEN Plus™ structured packing features innovative geometric optimization, achieving approximately 30% higher capacity at the same separation efficiency. The high-efficiency wire gauze structured packing adopts a special weaving method, ensuring low pressure drop and reduced liquid holdup, while delivering more than 50% higher efficiency compared with conventional wire gauze packings.
Equipment Configuration
DG™ Perforated Corrugated Structured Packing
This configuration combines a classic embossed surface with a perforated sheet design. The structure enhances liquid film turbulence, reduces HETP, and supports a broad range of separation applications.
DG Plus™ High-Efficiency Structured Packing
This series features smooth interlayer transition geometry that minimizes liquid accumulation and lowers flooding risk. Compared with conventional structured packing, operational capacity increases by approximately 30 percent under equivalent efficiency conditions.
DG™ Wire Gauze Structured Packing
This packing utilizes the capillary action of fine wire gauze to maintain stable wettability at extremely low liquid loadings, down to 0.05 cubic meters per square meter per hour. It is specifically suited for high-vacuum operations and heat-sensitive separation systems.
DG™ Grid Structured Packing
The grid-type structured packing adopts a rigid modular construction with smooth surface geometry. The design offers low pressure drop while providing strong resistance to coking, particulate blockage, and fouling, and supports simplified inspection and cleaning.
Equipment Manufacturing
DODGEN operates dedicated structured packing manufacturing facilities equipped with high-precision automated production lines.
The facilities support consistent fabrication of complex corrugated and woven geometries.
Processable materials include
- Stainless steel (304/316L)
- Duplex stainless steel
- Titanium
- Hastelloy alloys
- Copper
- Aluminum
These material options can meeting the requirements of corrosive operating conditions.
Manufacturing Advantages
Surface Treatment Technology
Proprietary metal surface texturing processes are applied to enhance surface wettability. This treatment promotes uniform liquid distribution and stable liquid holdup across the packing surface.
Complete Product Portfolio
Specific surface areas ranging from 100 m²/m³ to 750 m²/m³ are available. The portfolio covers conventional corrugated sheet packing, DG Plus™ corrugated packing, and high-efficiency wire gauze structured packing, with comprehensive model and size selections.
Strict Quality Control
Each production batch undergoes dimensional inspection of corrugation angle, corrugation height, and geometric tolerances. This ensures alignment between hydraulic performance, design models, and actual column operation, enabling predictable and reproducible separation performance.
