structured tower packing
High Capacity 252Y Distillation Packing
The impulse sections at the end of each packing layer decrease the local pressure drop at this point. This eliminates the sudden change in flow direction of the liquid and vapour phases at the packing layer interface.
With this special design the capacity of columns can be enhanced appr. 30%.
•Vacuum to over pressure
•Large scale production
•Increasing throughput on existing packed columns
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:
Lower pressure drop through the column
■Lower botoms temperature for heat sensitive systems
■Higher relative volatility for diﬃcult separations
■Lower energy consumption
■Reduced foaming tendency
Higher efficiency in the same tower height
■Large number of theoretical stages required
■Reduced reflux requirement
■Reduced vessel diameter
■Increased operating rates
Excellent liquid spreading characteristics
■Oﬀshore applications subject to permanent tilt and motion
Reduced liquid hold-up
■Smaller amounts of polymer inhibitor

1 General Provisions
1.1 This standard specifies the requirements for marking, specification and characteristics, materials, manufacturing requirements, inspection and acceptance, marking, packaging, storage and transportation of stainless steel orifice corrugated packing products, as well as the calculation of characteristic parameters of orifice corrugated packing.
1.2 The corrugated packing with stainless steel orifice plate is suitable for gas-liquid mass transfer separation tower equipment, and the applicable temperature of the packing is - 200 ~ 400 ℃.
1.3 The structured packing is suitable for the clean gas-liquid system without solid particles or suspended solids or easy to self assemble.
2. Reference standard: GB / T 4239 cold rolled stainless steel and heat resistant steel strip
Standard No. - year No. - packing model - inner diameter of tower Φ (mm)
For example, the inner diameter of packing tower is Φ 600mm, and p250i type stainless steel orifice corrugated packing is used, which is marked as follows: HG/T 21559.2—2005—P250I—600.
3.2 Specifications and characteristics
3.2.1 Stainless steel orifice corrugated packing is a number of corrugated plates pressed from stainless steel strip, which are vertically stacked and assembled into a disc-shaped structured packing according to the requirements of a certain diameter. The corrugations of the adjacent corrugated plates are inclined in the opposite direction, and the corrugations of the upper and lower adjacent packing plates are 90 ° crossed.
3.2.2 Before the corrugated plate is pressed, it is necessary to punch holes on the plate in advance and press the fine grain, or use the rolling grain equivalent to the fine grain.
3.2.3 Eight types of stainless steel orifice plate corrugated packing are listed in the table. The characteristic parameters of the type selection are the specific surface area of the packing and the angle of the corrugation, which can be selected according to the process design requirements.
