Patent ID: 6935096

Claim:
A gas compressor comprising: bringing means for bringing a low pressure entering gas at a high temperature; a convergent pressure reduction head (C 1 ) for increasing a gas speed of said gas toward a sonic speed, said head being placed after said bringing means; a convergent nozzle (C 2 ) placed after said convergent head (C 1 ), said convergent nozzle (C 2 ) performing a pressure reduction and cooling of said gas, wherein said gas is cooled and at the same time maintained at a high velocity; a cooling system (R) comprising a set of liquid spray diffusers for spraying a liquid in said convergent nozzle (C 2 ), said liquid spray diffusers having adjustable flow rates and adjustable positions and being distributed along a length of said convergent nozzle (C 2 ), enabling said gas speed to be maintained at a speed lower than a sonic speed along said length of said convergent nozzle (C 2 ); a divergent tube (D) placed after said convergent nozzle (C 2 ) for compressing the gas by reducing its speed to a normal subsonic outflow speed; and an evacuation line in which said gas is at a lower temperature and at a higher pressure.
