The invention is directed to a process and a system to compress air. The process involves the following steps, (i) compressing air in a compressor, (ii) cooling the compressed air as obtained in step (i) (iii) further compressing the air of step (ii) in a second compressor, (iv) further compressing at least part of the compressed air as obtained in step (iii) in a booster compressor, wherein the compressor in step (i) is an axial compressor, the compressor of step (i) and (iii) are driven by a common first driver and the booster compressor is driven by a separate second driver and wherein the compressors of steps (i) and (iii) are split into two individual casings.
