Production of low-purity oxygen in the next millennium.

Author(s) : AGRAWAL R., HERRON D. M.


Low purity oxygen (concentration less than 97% oxygen) is used in a wide array of applications: gasification of hydrocarbon mass, metal production, etc. These applications require large quantities of oxygen, typically in excess of 500 tons per day. Economical production of oxygen in such large quantities requires a careful selection of the cryogenic process cycle. A new process is described, with double distillation column cycle.
