Nitrogen Production Units

Air Liquide Offers a wide range of nitrogen production systems to suit all applications.

With the increase in remote activities in both offshore and onshore fields, increases the demand towards having more nitrogen without dealing with logistics. Our offer is to provide an on-demand, low maintenance and reliable source of nitrogen, through our on-site membrane-based nitrogen systems.

The use of an onsite membrane-based nitrogen system helps reduce pressure to the supply chain, increasing efficiency.

How it works

Nitrogen Production Units (NPU) take untreated compressed air and convert it into nitrogen at purities from 95% – 99.9%. This untreated air goes through a selection of filtration methods (coalescing, moisture and carbon) to remove hydrocarbons (oils), moisture and particulates. After this filtration, the air passes through the membranes where the molecules are separated. The nitrogen flows through the membrane fibres from one end to the other, and the other gases dissipate through the sides of the membrane to form what is called permeate gases (waste). All systems are ergonomically designed to allow safe operation and maintenance.

Our own technology

Air Liquide designs, engineers and manufactures hollow fiber membranes and complete membrane systems for gas separation and purification. With over 30 years of experience in nitrogen membrane systems, we offer membrane generators for sale and rent to our customers.
