Emulsions

[Glenfiddich]

would you have a good article or reference to emulsions 101?

i'd like to understand how they are formed and the basics.

i have had experience with emulsions created in slop tanks. the emulsion had a viscosity of 10,000 cP, if i recall correctly.

are emulsions even pumpable, with that kind of viscosity?

Milk is a natural occurring emulsion. Viscosity is probably 1-10 cP. Very pumpable.

Sorry, I don't know a single good reference solely on emulsions. I'd look for a rheology referemce and an emulsion polymerization referemce and a mixing reference. They should have something on it. Remember, Google is your friend.

Good luck,
Latexman

Try Evans and Wennerstr[ö]m The Colloidal Domain where physics, chemistry, biology and technology meet, VCH

i'm looking for more information on oil in water emulsions and water in oil emulsions.

ps. about the "search google" reply...do you think i was born yesterday?

Just generally speaking some of the factors that can cause emulsions are densities approaching each other for some reason, vapor entrainment, particle sizes, pH, and of course agitation.

I don't have experience with slop oil tank emulsions but would guess the high viscosity you recall was actually caused by some of the material that was sent to the tank or some decomposition process.

Nothing personal was intended, just good advice. Even a hint of a flame war is NOT tolerated here, so chill.

Chapter six in James Y. Oldsue's Fluid Mixing Technology is titled Liquid-Liquid Emulsions. It covers some of the basics like particle size distribution, which phase is dispersed and which is continuous, the importance of impeller shear stress, stability, dispersion criteria, and scale-up.

Even Albert Einstein did some viscosity work that is pertinent to emulsions and dispersion!

Good luck,

If you really want to understand how emulsion is form,oil in water or water in oil emulsion,check introduction to oilfield chemicals by as well as water technology textbooks.Really you may not obtain data on their viscocity but with field expierience, you could determine when you see one.hope this will help else reply me
