15% Lime tank: Guidance..
15% Lime tank: Guidance..
(OP)
Hello all,
I'm looking for a decent reference for specifying a 15% solids content lime tank.. specifically,
1. mixing type of device..(top agitator or other)
2. Type of sloping on tank..
is there a reference or design guideline i can purchase for these kinds of systems? (outside of my normal chemical experience..)

RE: 15% Lime tank: Guidance..
One important question is whether the agitator impeller would be even partially buried if the unit is off and the solids are allowed to completely settle. Mechanically the torque loads on a buried impeller are very high, so if this is unavoidable you'll need to oversize the entire agitator, prevent the agitator from stopping, or jet water on the impeller to loosen things before startup.
If you're interested I can put you in touch with one of our mixing process experts.

hope this help.

or would you use a jet mixing system with a pump..?
it is only a buffer lime tank..

I am not very familiar with square tanks, it could be because there is no(?) famous standard for their design and in the oil industry we try to avoid them.
Hope this help

However the slurry can freeze at 80 deg (it is essentially like cement / mortar and is a main ingrediant in such).
You will need to know if it quick lime (CaO) or hydrated lime (Ca(OH)2) and follow some of the ideas here:

I've never seen a rectangular mixing vessel.
Good luck.
