Mixing viscous liquids in storage tanks
(OP)
How can you mix a 55 m3 atmospheric storage tank with a viscous liquid (different products are stored) in the range of 200 to 6000 cp without using a mixer with huge motor?

To a ChE, the glass is always full - 1/2 air and 1/2 water.

Could you sparge with a gas?
At this viscosity an eductor will be of little use.

Sparging might just punch holes through the product and not really mix anything...I'm not very familiar with sparging applications though.
Just curious, is there a particular reason you don't want to use an agitator?

Pumping from multiple places could be a solution.
Two reasons for not wanting a mixer:1. It is horizontal tank. Due to space and process limitations it is very difficult to fit a vertical tank. Mixing horizontal tank with such volume and using a mixer is not possible.maybe multiple mixers? 2. The available electricity in the plant is very limited.
Btw i expect much higher power such as 100-150 hp.

Thanks for the info. Very interesting. Do you mean the time to circulate the liquid in the entire tank is < 1hr ? Do you have recirculation in the tank separately ? Difficult question but can you indicate how good the mixing is ? Is is only to create fine particles in the liquid?
RE: Mixing viscous liquids in storage tanks
Do you have recirculation in the tank separately? Yes we have that capability in some cases, but I am discounting that because it is inferior where we have mixers.
Difficult question but can you indicate how good the mixing is? If we added water to adjust solids or viscosity, it will be 99.9% homogenous in < 1 hour.
Is is only to create fine particles in the liquid? No. Our products are stable emulsions for the most part. Few that sit for long periods of time (weeks) without mixing can have some settlement.

Please let us know how it turns out.
