Method and Apparatus for Controlling Residence Time Distribution in Continuous Stirred-Tank Reactors
Patent
Overview
Overview
abstract
The present invention includes an apparatus and method for narrowing the residence time distribution of a continuous stirred-tank reactor, or CSTR, which includes the optional procedures of: decreasing the vertical cross-sectional area of the reactor's agitator blades; decreasing the RPM of the agitator blades; and increasing the reactor's L/D ratio. The CSTR can be used in the production of monovinylidene aromatic polymers, such as high impact polystyrene.
