Abstract
The Optimum construtions for gas-liquid agitation vessel have been determined as follows:
(1) The optimum submersion length of baffle plates is equal to half the liquid depth. Therefore, it is erroneous to use the baffle plates extending to the bottom of vessel as usually be found in Penicillin broth tanks.
(2) The optimum sparger loop diameter is equal to 80% of the paddle length.
(3) The optimum baffle plate width is equal to 18% or 12.5% of the tank diameter respectively, according to the number of baffle plates is 2 or 4.
(4) There is a certain minimum agitator speed needed, to absorbe gases effectively.
(5) Several types of agitators were compared each other.
