MINOX DE-OXYGENATION SYSTEM

The Grenland Minox systems are based on a patented technology for nitrogen gas stripping. The nitrogen gas is effectively mixed with the water in static mixers (a two stage system) or in a packing (compact tower system).

This results in an extremely effective mass transfer and residual oxygen content of less than 10ppb in the water is achieved without the use of oxygen scavenger.

The oxygen is stripped from the water by the nitrogen. The nitrogen is then catalytically purified and recycled.

The Grenland Minox system is particularly well suited for de-oxygenation of water (Minox DeOx).

• Seawater for injection in oil wells and different types of open and closed industrial water circuits
• Avoid corrosion of pipes
• Avoid bacterial growth and clogging of the reservoir

Other possible applications:

• Units for removal of oxygen from lighter hydrocarbon feed in refineries
• Units for removal of oxygen from ethanol/methanol used for hydrate prevention in natural gas transport lines
• Units for removal of oxygen from ventilated produced water for re-injection

The Minox™ technology offers:

• Compact and economical systems compared to the competitors
• The compact Minox de-oxygenation process can be delivered in a wide range of capacities and for almost any process environment with regard to pressure, temperature etc.
• Low consumption of utilities
• Dry, robust catalyst
• No need for fine filtration of water
• No need for booster pumps
• Effective mass transfer
• Non-hazardous area classification can be obtained
• The Minox process is totally environmental clean
