ABSTRACT:
A method and apparatus for making gaseous oxygen at a delivery pressure in a single column oxygen generator. In accordance with the method and apparatus, a column bottoms stream composed of the product is pumped to the delivery pressure and then vaporized. A liquid coolant stream used in condensing reflux is recompressed by a recycle compressor and then recycled back into the bottom of the column. Such recycled stream has a higher nitrogen content than the column bottoms. Part of the nitrogen tower overhead, not used in forming the reflux, is turbo-expanded by a turbo-expander coupled to the recycle compressor.
