Blending in above ground storage tanks with side-entering
Hemrajani (2004) has discussed mixing in storage tanks with side-entering agitators and gives recommendations for power input per volume for various grades of crude oils. For light to medium crudes he recommended that the power input per volume should be 0.4 HP/kbbl (1.87 W/m 3) and this level of mixing is required to keep sludge suspended.This new energy saving turbine agitator can be used effectively for many chemical and biochemical engineering.

Effect of Agitator’s Types on the Hydrodynamic Flow in an Agitated Tank
The aim of this paper is to study the effect of agitator’s types on the turbulent flows in stirred tanks without and with baffles. The hydrodynamics behavior induced by four different agitator’s types: a Rushton turbine (RT), a circular blade turbine (CBT), a diverging triangular blade turbine (DTBT) and converging triangular blade Mixing of substance in stirred tank just depend on free diffuses when there is no agitation in ST. But, besides to promoting substance mixing, agitation also changes the fluid flow and form various flow field structure in ST just like the Fig. 8 [30, 31] showing. The change of flow field means the direction and magnitude of the fluid velocityStudy on instability strengthening of flow field in stirred tank

Types of Agitators, Agitator's Design and Significance
Propeller Agitators : A propeller agitator is shaped with blades tapering towards the shaft to minimize centrifugal force and produce maximum axial flow. Propeller agitators are popular for simple mixing jobs. Turbine Agitators : Yet another type of process agitator is the turbine agitator.I am designing anchor type agitator. Tank Diameter is 2525 mm, Tank height is 2250 mm, Liquid Viscosity is 3000 Cp, Density is 1500 Kg/m3, Blade diameter is 2480 mm, Blade width is 50 mm, Blade thickness is 10 mm, Hight is 16oo mm.
