Effect of solids concentration on solid-liquid mass transfer in an agitated dissolution system

Suspension of solids in mechanically agitated vessels is important for many industrial solid-liquid processes such as dissolution and leaching. Although solid-liquid mixing in an agitated vessel has been studied extensively, mass transfer in such systems, especially under high solid loadings, has received insufficient attention. Also, the current knowledge on the effect of active to inert particle ratio on mass transfer is limited. This paper investigates the effects of solid concentration and active-inert particle ratio on solid-liquid mass transfer in an agitated dissolution system under baffled and unbaffled conditions
