Abstract:
Process for feeding a gas-consuming unit (HF), in which:i) a feed flow consisting of a gas mixture is compressed in a compression unit (21);ii) a first part (28) of the compressed mixture is sent to the gas-consuming unit (HF);iii) a second part (23) of the compressed mixture is sent to a separation apparatus (25) which separates the mixture to produce two gas flows, one of which is at a higher pressure than the other;iv) the gas flow (24) at higher pressure is sent to the gas-consuming unit (HF);(v) the other gas flow at a lower pressure (26) is sent for compression to at least said compression unit (21), and the gas thus compressed is sent to at least one gas-consuming unit (HF, HF2, HF3); and(vi) the feed flow is air and said two gas flows are both enriched with the same one of nitrogen or oxygen.
