A feedstock hydrogen-enriched gas (3) is supplied to a PSA purification unit (1) which delivers pure hydrogen at a production output (4) and a hydrogen-deficient gas at a residual output. Said hydrogen-deficient gas is compressed (9) and injected into a line (10) wherein a gaseous combustible mixture circulates whose part (12) is extracted upstream of the PSA unit (1), compressed (13) and reinjected into said feedstock of the PSA unit (1). Said invention is used, in particular for petrochemical sites.
Un gaz de charge riche en hydrogène (3) est fourni à une unité d'épuration PSA (1) fournissant en sortie de production (4) de l'hydrogène pur, et en sortie de résiduaire (5) un gaz appauvri en hydrogène qui est comprimé (9) et injecté dans une ligne (10) dans laquelle circule un mélange gazeux combustible dont une partie est extraite (12), en amont de l'unité PSA (1), comprimée (13) et réinjectée dans le gaz de charge de l'unité PSA 1.
