| Abstract;Gas dispersion characteristics of a single impeller in a fully baffled cylindrical pilot scale stirred vessel(T=0.72m) were studied for newly developed impellers, which are a 6-bladed hollow blade discturbine(6HB) and Lightnin A315(A315), in addition to the traditional 6-bladed Rushton disc turbine(6DT), under unarerated and aerated conditions in water. The power drawn, gas hold-up and kLa(oxygen mass transfer rate) obtained were compared with those for the 6DT reported in literature. As a result, it was found that the gas handling capacities of the 6HB and A315 are superior to that of the 6DT. (author abst.) |
