I have a question regarding air separation
Thread Content
I would like to ask: 1. What are the main uses of the oxygen produced by air separation units? 2. What to do with the remaining oxygen after it has been used up? 3. What is the concentration of residual oxygen? 4. Is the oxygen and nitrogen separated stored in liquid form or in gas form? What is the concentration?
For our company, oxygen is primarily supplied to Texaco Gasification for an incomplete oxidation reaction to produce syngas (the main components of which are CO and H2). The remaining oxygen is stored in liquid form and then sold at a purity of 99.5%.

It depends on the environment in which the air separation unit is used. In a steel plant, it is obviously used for steel production; in coal gasification processes, it serves as a gasifying agent. Companies in the aerospace industry produce liquid oxygen mainly as a fuel source! The oxygen produced by our company’s air separation unit is primarily used as a gasifying agent for the gasifier, to generate the raw gas needed for methanol production!
The excess oxygen is of course taken out and sold as a product. We store it in liquid form, which allows for a larger storage capacity!
Our oxygen is sold externally and is stored in liquid form, with a concentration of over 99.9%
