Blending of Miscible Liquids

Agitated and jet mixed vessels are used for blending duties. The choice of equipment will depend on the viscosity of the fluid, the desired blend time, and the size of the vessel. The chapter is divided into four sections that cover design rules for

BLENDING OF MISCIBLE LIQUIDS. Miscible liquids are blended in relatively small process vessels by propellers or turbine impellers, usually centrally mounted, and in large storage and waste-treatment tanks by side-entering propellers or jet mixers. In a process vessel all the liquid is usually well agitated and blending is... 

From the previous classification of mixing problems in section 1.1 it will be clear to the reader that the term mixing covers much more than processes in which non-uniformities in composition are reduced. This latter type of operation, e.g. the blending of miscible liquids or powder mixing, are both duties for which a method of evaluation of mixture quality is necessary to... 

Now that the fundamental principles have been reviewed, consider the apphca-tion of mixing miscible liquids. Related topics Stirred Tank Reactors, Sections 6.27-6.29. For the blending of miscible liquids the main characteristic is to create flow or pumping. However, there is a tradeoff between pumping and power.
