THE MINOX PROCESS

Minox process for deoxygenation is a state of the art technology for removing oxygen from water before it is reinjected into reservoirs. We have more than 20 years operational experience in applying our technology in offshore projects and it is a proven technology. Our module has a low weight, small footprint and low height, and is flexible in design and capacity. Our process has a wide operational range, can be applied in non-hazardous areas, operates on positive pressure and requires no chemicals (oxygen scavenger) to meet required specifications.

During the last 25 years, Minox has continuously improved our technology and updated the system design to provide our customers with state of the art solutions. We have several generations of our systems in operation today.

We are actively working on upgrading all our systems to 4thgeneration systems which have the following features in place:

  • Cyclonic internals in the separator vessels
  • Improved compressor type and design
  • Improved control of the fuel injection
  • Improved chemical reactor control

Upgrading the older generation systems to 4th generation technology gives the following advantages:

  • Reduction of maintenance requirements
  • Quicker start-up times
  • Fully automatically controlled systems
  • Reduced chemical requirements

In order to “find the generation of your system“, please look into our reference list that you will find under Products and References.

Minox Compact

Minox®Compact

A key process feature of this Minox deoxygenation system is the method of contacting the nitrogen stream with the water. This is done in static mixers where co-current turbulent flow is achieved, producing highly efficient mixing of water and gas, simultaneously stripping the dissolved oxygen from the water – to very low concentrations. The Minox®Compact edition doesn’t require any scavenger chemicals.

The low system weight combined with flexible and skid mounted design allows for efficient tailoring in accordance to the customers’ specifications. Each unit can be tailor made to fit into a given space which makes it possible to install on existing platforms, or when conventional deaeration systems are being upgraded. In such cases, the process will not only enable injection water volumes to be increased with a reduced oxygen content, but the need for scavenger chemicals is eliminated or greatly reduced, as well as saving fuel gas for stripping.

The Minox®Tower

Based upon the same basic principle of cycling and purifying nitrogen gas, the Minox®Tower system offers a competitive alternative to vacuum and fuel gas deaerators, yielding a very low residual O2 content. In this system the contacting between the nitrogen stream and the water is done through counter–current flow over a packed bed of structured packing. The system can operate under atmospheric, or a few bar pressure. The danger related to using natural gas as stripping gas is removed. Reduced weight and lower operational expenditures are among the other product advantages.

It is even possible to convert existing vacuum or fuel gas towers into Minox®Tower. Vacuum tower conversion into a Minox®Tower makes it possible to increase water flow through the tower. The system allows for a residual O2 content down to 20 ppb or less, without applying scavenger chemicals. Next to that lower operational expenditures and increased discharge pressure are additional advantages. By converting a fuel gas tower into Minox the danger related to fuel gas as stripping gas can be removed, additionally unnecessary waste of fuel gas can be avoided.

Minox DryGas production platform equipment

The Minox®DryGas

One of our current new developments is Minox®DryGas, an innovative, compact and lightweight system for dehydration of natural gas. The new technology, based on static mixers and high tech separation, will replace the existing, old technology based on high and heavy contactor towers.
