PREDICTION OF MIXING TIME IN AIRLIFT REACTORS

Abstract A correlation was derived for prediction of the mixing time in airlift reactors in the air-water systems, using gas velocity and construction characteristics of the reactor only.

Minimum fluidization velocity of large particles in a draft tube airlift reactor

The effects of solids loading and diameter, liquid properties and draft tube to outer column diameter ratio (D D /D) on minimum fluidization velocity in a draft tube airlift reactor (DT-ALR) are presented

Mixing time in gas—liquid—solid draft tube airlift reactors

The results of an experimental investigation of the mixing time in three-phase draft tube airlift reactors are presented. The influences of the gas superficial velocity, draft tube to outer column diameter ratio, concentration and diameter of solid particles on mixing time and circulation time were studied

Flowing solids dynamic holdup in the countercurrent gas-flowing solids-fixed bed reactor

The effect of packing properties on the flowing solids dynamic holdup in the countercurrent gas-flowing solids-fixed bed reactor was investigated. The correlations for the prediction of flowing solids dynamic holdup in preloading and loading regimes were proposed.
