Abstract: THE INVENTION RELATES TO A METHOD OF MIXING A GAS WITH LIQUIDS IN A TUBULAR REACTOR BY FEEDING THE GAS AND THE LIQUIDS TO A MIXING zONE. THE INVENTION ALSO RELATES TO AN SEPARATUS FOR CARRYING OUT THIS METHOD. RAPID MIXING ID EFFECTIVE BY FEEDING A STREAM OF LIQUID TO THE MIXING ZONE THROUGH ONE OR MORE NOZZELS WHOSE AXS EXTEND IN THE SAME DIRECTION AS THE AXIS OF THE MIXING ZONE, IN INJECTED LIQUID HAVING A VELOCITY OF FROM 5 TO 100 M./S., WHILST A SECOND STREAM OF LIQUID OF MUCH LOWER VELOCITY IS INTRODUCED INTO THE REACTOR INLET ZONE SURROUNDING SAID NOZZEL. THE GAS IS FED TO THE MIXING ZONE THROUGH ONE
OR MORE GAS INLETS LOCATED NEAR THE ORIFIECES OF THE LIQUID NOZZELS. THE MEAN CROSS-SECTIONAL AREA OF THE MIXING ZONE BEARS A SPECIFIC RATIO TO THE CROSS-SECTIONAL AREA OF THE ORIFICES OF THE LIQUID NOZZLES AND THE LENGTH OF THE MIXING ZONE BEARS A SPECIFIC RATIO TO THE HYDROLIC DIAMETER THEREOF. THE METHOD AND APPARATUS ARE PARTICULARLY SUITABLE FOR CARRYING OUT REACTIONS IN WHICH SHORT RESIDENCE TIMES ARE DESIRABLE AND THE REACTION PRODUCTS MUST NOT RECONTACT THE STARTING MATERIALS.-

Abstract: A method of rapidly mixing liquids which differ greatly from one another as regards their volume and/or density, to form emulsions or homogeneous mixtures. One or more jets of the liquid dispersing agent are passed through nozzles at a velocity up to 100 m/s to an impulse exchange chamber, which is located in the liquid medium and extends in the downstream direction, together with the liquid to be dispersed, which latter liquid is ejected in the immediate proximity of the orifice of the nozzles providing the propulsive jet. The average hydraulic diameter of the impulse exchange chamber is equal to from two to 20 times the diameter of that nozzle which is equal in cross-sectional area to all the nozzle orifices present, and its length is equal to from two to 30 times its hydraulic diameter.
Abstract translation: 快速混合液体的方法，其相互之间的体积和/或密度彼此大不相同，以形成乳液或均匀的混合物。 液体分散剂的一个或多个射流以高达100m / s的速度通过喷嘴，与位于液体介质中的脉冲更换室一起，并与待分散的液体一起沿下游方向延伸， 后者的液体在提供推进射流的喷嘴的孔口附近被喷射。 脉冲更换室的平均水力直径等于该喷嘴的直径的2至20倍，其横截面积与存在的所有喷嘴孔相等，并且其长度等于其液压的2至30倍 直径。
