Power consumption (Part I) and liquid phase mixing time (Part II) were measured in 0.57, 1.0 and 1.5 m i.d. vessels. A pitched blade downflow impeller (PTD) was used. Design details of the PTD impeller such as diameter (0.22T to 0.5T), blade width (0.25D to 0.4D) and blade thickness (2.8, 4.3 and 6.4 mm) were studied. The effect of …

Usually the move is from lab-scale to full-scale via a pilot-scale. The pilot-scale must be sufficiently large to provide representative information for the full-scale design. In this way, we minimise the risk of poor process performance and long commissioning times. Typically for a new agitated vessel we will operate at the litre …
