Product tanks that contain a stock produced by the blending of two or more components and/or additives should be
equipped with mixers. Mixing can be accomplished by a jet nozzle with a recirculation system or by SEP mixer.
The final selection should be based on economics. The mixing is required for the following reasons:
1. To prevent stratification of components within the tank.
2. To allow for re-mixing after the addition of a component to adjust an off-test blend.
3. To prevent temperature stratification in large hot oil tanks [above 265¡ÆF (130¡ÆC)]
