Air separation is used in a wide variety of industries such as Oil & Gas, Chemical, Paper, Metallurgy and others. Air separation plants are used to separate atmospheric gasses into its various primary components like oxygen, nitrogen, argon and other inert gases.

The main products from Air Separation Units (ASU’s)are oxygen and nitrogen. Oxygen & cryogenic valves are widely used in the air separation industry and Alliance can provide complete valve solutions for this critical service.
