Deaeration of sea water

Typical water injection system circuit

The deoxygenation system for injection water, can be delivered in two different versions; Minox DeOx System – 2 Stages, or Minox Deox System –Compact Tower.

The MinoxTM DeOx System – 2 stages

This is the ultimate deoxygenation system configuration available in the market today. It gives extremely small and light units and requires a minimum of maintenance and utilities. 

Features:

• Extremely compact and flexible layout
• Significant weight and volume savings compared to conventional systems
• Low height, fits in-between decks
• Residual oxygen level less than 10ppb without the use of oxygen scavenger
• Elimination of booster pumps
• No need for fine filtration
• Easy installation and low maintenance frequency
• Can be located in hazardous and non-hazardous area

The first commercially sold MinoxTM Deoxygenation system (2-stage) was installed on Saga Petroleum's Snorre TLP in 1991. Today's edition is even more compact.

The MinoxTM Deox System – Compact Tower

By utilizing the MinoxTM process in conjunction with a tower and packing, the same technical features as the 2-stage system are achieved. It will however require more space and support than the 2-stage system, but still significant less than a conventional system. This means that overall, for most new installations, the 2-stage system will be more cost effective.

Features:

• Higher capacity compared to conventional towers (same size)
• Residual oxygen level less than 10ppb without the use of a scavenger
• Elimination of booster pumps
• Low maintenance frequency
• Proven technology
• Can be located in hazardous and non-hazardous area
