Abstract
A process and an apparatus are disclosed for air fractionation by means of rectification. Nitrogen (16) withdrawn from the process is heated to an intermediate temperature, withdrawn, in part (30), out of the primary heat exchanger (17), and engine-expanded (31). The resultant expanded gas (32) transfers its cold in the primary heat exchanger (17) to air to be fractionated (1) and is then recompressed (33, 36).
