A process and installation for the separation of air by permeation, for the production of high purity nitrogen. The installation comprises in series an air compressor (2), a refrigerator (3) cooled by air or water, a unit (4) for filtering out oil and water, an air reheater (5) and a permeator (6). The air reheater (5) is provided with a device (18A) for adjusting the temperature as a function of the temperature of the final refrigeration fluid that cools the compressed air.
[ What is claimed is:] [1.] Installation for the separation of air by permeation, for the production of nitrogen, comprising in series an air compressor, a refrigerator, a unit for filtering out oil and water, an air reheater and a permeator, the reheater having means for adjustment of the temperature of air entering the permeator as a function of the temperature of a final refrigerant in the refrigerator.
