Abstract

A process for mixing or dispersing liquids is provided that includes introducing liquids to be mixed or dispersed into a mixing device having a cylindrical support. The cylindrical support includes an inlet nozzle having a bore which is in fluid communication through a turbulence chamber with a bore of an outlet nozzle, wherein the bores of the nozzles are axially spaced apart relative to one another. The liquids are then allowed to enter the turbulence chamber through the bore of the inlet nozzle where the liquids are mixed or dispersed. The mixed or dispersed liquid is then recovered from the outlet nozzle. Various devices for mixing or dispersing liquids are also provided.
