ABSTRACT:
Auxiliary gas is withdrawn from the heat exchanger during cooling or reheating at an intermediate temperature which is close to the vaporizing temperature of the oxygen or nitrogen high pressure product stream, then compressed by a cold compressor and reintroduced in the heat exchanger. The invention is particularly applicable to the production of gaseous oxygen at a pressure greater than about 15 bar.
