ABSTRACT OF THE DISCLOSURE The process is for the production of gaseous 02 at an elevated pressure by low temperature rectification of air, in which air is compressed, purified, and at least in part, is cooled in a first heat exchanger in heat exchange with a rectification product and is passed to the rectification. A second gas stream is compressed to a higher pressure, cooled in a second heat exchanger in heat exchange with the rectification product and is expanded and likewise is passed to the rectification. In the process, oxygen in liquid form is withdrawn from the rectification, pumped to the desired pressure, and , in heat exchange with the compressed gas stream, is evaporated and heated. A third partial stream of gas to be fractionated is cooled in heat exchange with the fractionation product.
