An air separation apparatus and method in which a high pressure gaseous product is produced as a liquid, pumped to a delivery pressure and then vaporized prior to its discharge as product. In order to accomplish the requisite vaporization, a subsidiary stream of incoming air is compressed by a booster compressor and then passed into indirect heat exchange with the pumped liquid in a falling film evaporator. The falling film evaporator maintains an essentially constant temperature difference between the air and falling film, formed of the pumped liquid. As a result, a very small temperature differences can be maintained as compared with the conventional use of a thermosyphon reboiler. As a result, less booster compression is required for the subsidiary air stream over a prior art plant.
