Membrane Deaeration

Membrane degassing is an ideal solution for the quantitative removal of oxygen and carbon dioxide at ambient temperature.

In the membrane degassing process, water comes into contact with a purge gas stream through a semipermeable membrane. While water cannot permeate through the membrane, the dissolved gases are forced to flow through it with the low partial pressure in the gas phase as the driving force. According to each customer’s expected performance, the purge gas stream could be pure nitrogen, compressed air, vacuum conditions, or a combination.

Cannon Artes is qualified by 3M, the world leader in the field of membranes for degassing of liquids, for the implementation of membrane degassing in the Injection water treatment in offshore oil&gas projects.

Carbon dioxide is also a common issue in many deionization and Demineralization plants, as it contributes to the anionic load.

In an ion-exchange process, lowering the anionic load implies reduced operating costs due to lower consumption of caustic soda in the regeneration of the anionic resins. In reverse osmosis, CO2 removal reduces the dissolved solids content and specific conductivity.

We offer our clients the support to investigate, test, design, manufacture, commission, and start-up of water treatment systems based on membrane deaeration.

If you think membrane degassing is something new, you can talk to our engineers with more than twenty years of experience in this area!
