Hi,

I am in design field.
Can you tell me how to design a agitator, which is used in sugar/ethanol plant?
Or give me some general idea about the design of agitator.

Dear,

If you are going to design the agitator you must know the following data:

physical properties of the fluid, ( density, viscosity, gravity )
Application ( gas dispersion, blending or suspesion etc. )
Pilot plant data ( Type of impeller, dimensions, power required per m3, if gas dispersion then gas hold up )


For the designing of the agitator we must know its application for the perpose we are going to use
Power no. is very important while designing and it is depends on the resistance to the flow by its shape

Foe eg.

If I want to design an agitator for the gas dispersion reaction the I must have to decide the right impeller ( like chemineer BT-6 ( curve blade disc turbine ), turbine-disc impeller etc.)

which having the power no. in the range of 3.5 to 5
then you can calculate the power requirement by:


Q = Np . row. N^3. Da^5

Np = Power no.
row = density Kg/ m3

N = RPM
Da = impeller Dia m

Q = KW
