Abstract
A mixing method and system for the thorough intermixing of liquids of widely different viscosities in which there is interposed at least one perforated plate in the line of flow ahead of a conventional static mixer.
Claims2
A method of mixing a low viscosity liquid with a high viscosity liquid where the proportion of said low viscosity liquid to said high viscosity liquid is in the volumetric flow ratio range of about 0.01 to 0.2, and where the ratio of viscosities of said high viscosity liquid to said low viscosity liquid is in the range of about 4 .times. 10.sup.3 to about 10.sup.6 comprising introducing said low viscosity liquid under pressure into a flowing stream of said high viscosity liquid, thence flowing said liquids through a perforated plate establishing a multiplicity of wakes of said low viscosity liquid on the downstream side of said plate, and then impelling said low viscosity and said high viscosity liquids through a static mixing element.
