Minox® De-oxygenation
The fundamentals
 Henry’s Law: the solubility of a gas in a liquid is directly proportional to the
partial pressure of the gas above the liquid
 Stripping process using ultra pure nitrogen gas
 Stripping gas regenerated and re-circulated
Ultra compact Minox 2-stage edition
Contacting through co-current turbulent flow

Minox® Deoxygenation Systems
Key advantages
1. The most efficient and compact de-oxygenation solution available

Purity < 10 ppb without oxygen scavenging chemicals

Up to 70% weight savings compared to vacuum system

Small footprint, low building height and low weight

Energy saving, compared to vacuum system
2. Operates on positive pressure (inlet pressures up to 20 barg are
acceptable)
3. Pressure drop over the systems: 0,5-2,0 bar, can eliminate booster
pumps upstream WI pumps
4. Highly flexible in design and capacity (1500 – 378 000 BWPD single unit)
