Laboratory Structured Packing
Laboratory Structured Packing
Laboratory structured packing is a kind of structured packing with small diameter which is range from 20 mm to 100 mm. The metal wire gauze structured packing consists of multiple strands of very fine wire. It has a large surface area range from 900m2/m3-2500m2/m3.
For small laboratory column diameters we can offer specially designed packing types (900Y, 1100Y, 1700Y and 2500Y) for a preliminary assessment of a separation task. It can provide the highest number of theoretical stages while keeping a small pressure drop. The material could be stainless steel and different alloys.
Description

Application
- Where a high number of theoretical stages is required with low liquid loading
- Pilot plant columns.
- Laboratory columns from 20 to 100 mm.
- High purity separation task.
- Deriving of reliable scale-up rules.
