These gases can be separated in an air separation process where the air is condensed, cooled and separated by molecular weight in a "cold box." Once separated, the gases are again compressed for storage, transportation or further processing. MSG® TURBO-AIR® and MSG® compressors have a long history of reliable performance in Air Separation applications. Ingersoll Rand has the technology ...

Air Separation into Oxygen, Nitrogen, and Argon Background The purification of various components of air, in particular oxygen, nitrogen, and argon, is an important industrial process. A feasibility study is to be performed to investigate the possibility of producing 1500 metric tons per day of 99.5% oxygen, 5000 metric tons per day of 99.5% nitrogen, and 58 metric tons of 99.9% argon from air ...

Non-cryogenic air separation plants are compact and operate at near-ambient temperature and pressure. Once installed, they can usually be brought on-line in less than half an hour. Unlike cryogenic plants which use the difference between the boiling points of nitrogen, oxygen and argon to separate and purify those products, non-cryogenic air separation processes use physical property ...
