    Lactic acid separation by the liquid membrane at high pH

  • Popis výsledku v původním jazyce

    Mass transfer based processes are emerging in the biobased, chemical and food industry. For the processes with gas-liquid mass transfer rate as the controlling factor, the volumetric mass transfer coefficient, kLa, becomes the indispensable parameter. At the moment the volumetric mass transfer coefficient is commonly predicted on the base of literature correlations. Application of many correlations is limited by the way of their development (some of the correlation were established just only for one vessel size or one ratio between impeller diameter and vessel diameter). With an intent to create an appropriate correlation for kLa prediction in non-coalescent batch the broad experimental dataset was measured by Dynamic pressure method (DPM) which have been demonstrated to be physically correct in the past. Our previous works aimed at the kLa dependencies in a viscous and in the coalescent batch resulting in appropriate correlations that are viable for those process conditions. Our next target is to describe the relationship between various impeller diameters and transport characteristic (mainly kLa) in the non-coalescent type of the batch. The experiments were carried out in a multiple-impeller vessel equipped with Rushton turbines (of several diameters) and in both, laboratory and pilot-plant scale. Various impeller frequencies and gas flow rates were used for experiments. The experimental based correlation for kLa prediction in the non-coalescent batch is presented. Presented correlation should be applicable to industrial design of gas-liquid contactors with non-coalescent batch.
