How air separation works
At Messer, air is the raw material from which the individual gaseous components oxygen, nitrogen and argon, as well as the rare inert gases krypton and xenon are extracted in their purest form. We obtain these pure gases using air separation units. These are utilized in a number of industrial processes to make them both safe and profitable.
The air is drawn in large compressors for compression. The gas mixture is cooled until its liquid stage in heat exchangers. This occurs at extremely low temperatures of up to negative 196 degrees. Since the individual air components vaporize at different temperatures, they can be separated in tall separation columns and extracted in their pure form.
Pipeline gases
Gas supplies can be provided to industrial areas with several major companies, such as steel producers or chemical and pharmaceutical firms, via a system of pipelines managed by Messer.
Acetylene
Carbon monoxide
Compressed air
Hydrogen
Nitrogen
Oxygen
On-site
If it is not possible for a major customer to connect to our pipeline system, we will provide a production system on-site. It is often possible to operate these systems remotely from our locations.

Gases in road tankers and storage tanks
The most economically effective way to supply “medium” volumes is to transport and store them as cryogenic liquid and compressed gases in road tankers. We will bring our products to your site in insulated storage containers with vaporizers or in pressure vessels.
