- For a high number of theoretical stages per unit height
- Vacuum from 1 mbar to high pressure applications
Gauze packings
High separation efficiency at low pressure drop
BX gauze packing has been successfully employed in the industry for over 50 years, allowing difficult separation tasks to be accomplished. CY packing was developed for separations that require even a larger number of theoretical stages. BXPlus and CYPlus are the latest generation of gauze packings and offer the same efficiency as BX respectively CY with a 20% lower pressure drop.
- Monomers from plastics (MDI, DMT, etc.)
- Fatty acids, fatty alcohols, fatty acid esters
- Mono, di, tri, and tetra-ethylene glycols
- Pharmaceutical products (vitamins, etc.)
- Fragrances (menthol, geraniol, etc.)
- Separations of mixed isomers
- Fine chemicals
Key characteristics
- Large number of theoretical stages

- Where minimum pressure drop per theoretical stage is important
- Low overall height
- Batch and continuous columns
- Pilot columns (reliable scale-up)
Key characteristics
Suitability
Of only limited suitability for
- Fouling substances that form deposits
- Non-wetting liquids (e.g. reduced NTSM with water)
