Suspension and Liquid Homogenization in High Solids Concentration Stirred Chemical Reactors

Solid particle distribution of moderately concentrated suspensions in a pilot plant stirred vessel

“…This phenomenon has frequently been observed in the past and was firstly discussed by Musil [21]. Further papers [4,[22][23][24][25][26][27][28][29][30][31] describe the effects on this phenomenon of particle size and concentration, impeller type and speed, impeller off-bottom clearance, stirrer and vessel size, mixing time and physical properties of the system. Several references are indirect, focused on the study of various suspension system parameters, e.g.…”

Internal annular wall jets: Radial flow in a stirred tank

“…Ž . as slurry catalyst reactors Bujalski et al, 1999. Bittorf 2000 has shown that the position of the interface can be determined using the decay of U in the wall jet.…”

Predicting Power for a Scaled‐up Non‐Newtonian Biomass Slurry

“…At this scale, a 45°PBT and an A310 hydrofoil were tested. These were chosen as they are widely used, even in non-Newtonian systems, and can provide a baseline impeller setup [26][27][28]. Additionally, since these impellers can function in both Newtonian and non-Newtonian regimes, they can be used in enzymatic hydrolysis reactions where the rheology of the slurry changes drastically during the course of the reaction where the solids content starts high and ends low.…”
