<p>A process for drawing in and compressing gases and mixing the same with liquid which comprises propelling a jet of liquid from a propulsive nozzle which is shaped to provide an outlet region of minimum cross-sectional area, causing the resulting jet to become premixed with the gas in a coaxially arranged mixing nozzle which is situated downstream of the propulsive nozzle and is shaped to provide an outlet region of minimum cross-sectional area and minimum hydraulic diameter, and introducing the resulting premix into a region of minimum cross-sectional area of a coaxial, open-ended tube located in a body of the liquid, whereby the premix becomes admixed with liquid in the tube and with liquid drawn into the open inlet end thereof as a result of the flow of the premix and whereby compression of the gas in the premix occurs, in which process (a) the liquid jet from the propulsive nozzle has a speed of 10 to 70 m/sec, (b) the distance between the regions of minimum cross-sectional area of the propulsive nozzle and mixing nozzle is from 1 to 10 times the minimum hydraulic diameter of the mixing nozzle, (c) the minimum cross-sectional area of the mixing nozzle is from 1.5 to 15 times the minimum cross-sectional area of the propulsive nozzle, (d) the minimum cross-sectional area of the tube located in the body of liquid is from 1.2 to 20 times the minimum cross-sectional area of the mixing nozzle, and (e) the length of the region of minimum cross-sectional area of the tube located in the body of liquid is up to 20 times the hydraulic diameter of the tube in that region.</p> |
