Liquid Mixing in Agitated Vessels - RESI
MULTIPLE IMPELLER GAS- Liquid CONTACTORS1005 Liquid Mixing in Agitated VesselsTo express the degree of Mixing in a stirred vessel , an expression is desirable to showhow far the state of Mixing deviates from the ideal complete Mixing . The most simple andpopular index used in Mixing studies is so called Mixing time. Figure shows the processof Mixing in a stirred vessel . The termination point of this tracer experiment was taken whenthe reponse curve has reached%5%100 CCC)t(Co ( )where C , Co, and C(t) are tracer concentration as the detected point at equilibrium, t=0 andtime t respectively. The time needs to reach the termination state is known as Mixing time of the system under the given condition as shown as tM in Fig..Fig. Process of Mixing and definition of mixingThe role of baffles in a mechanically Agitated vessel is to prevent swirling and vortexingof Liquid and to stabilize the power drawn by the impeller, thus greatly improving the mixingof Liquid .
