Agitator sizing in non-cylindrical tanks

Agitator sizing in non-cylindrical tanks

Agitator sizing in non-cylindrical tanks

(OP)
Dear All,

I'm trying to size an agitator for an horizontal tank (to be more specific, for an iso-container I'm using for batch production).

My problem is that in the literature (for instance Coulson & Richardson - vol.6) I am not being able to find anything to solve the question (apparantly the commonly used correlations are valid only to the conventional, vertical tanks)...

Does anyone know where I can find some documentation about this?

Thank you!

If your application is important, you should lets a mechanical mixing expert size the mixer.

Is jet mixing an option?  That's one way that has a chance of reaching the ends of the vessel if the nozzle (we use a reducer) can be properly placed and positioned.

Good luck,

Agree with Chance17. Contact a mixer manufacturer (Eg. Chemineer, Lightnin ... )

RE: Agitator sizing in non-cylindrical tanks

If it was me I would go with a pump around loop and eductor mixers.  you could do a top entry mixer but you are only going to get part of the vessel mixed, even with  a lot of horsepower, which will be hard to hold up.

Dears Hello/Good Afternoon,

I tend to second Stonecold

that the "dead" areas or pockets of any environment that requires mixing,can only be broken& transported into thorough mixing process through

withdrawal into a pump suction and then re-injection into the other mixed/under mixing bulk

That's three then.  "Jet mixing" is my terminology for "a pump around loop and eductor mixers.

Good luck,

There is an awful lot of mixing done in rectangular tanks out there. There is no problem at all when dealing with low viscosity liquids that don't contain something that will settle.
