In air separation plants, the oxygen is separated from the air as a liquid at substantially atmospheric pressure. The conventional system is to vaporize the liquid at this low pressure and correspondingly low temperature and to recover the remaining refrigeration by heat exchange of the gas with the incoming air. Oxygen gas at ambient temperature is then compressed to the desired delivery pressure. An example is shown in Fig. 1.
