An investigation is made into the net flow rate and fluid viscosity influence on backmixing in multistage, baffled and unbatlled, mixer columns. Results are correlated with reference to both interstage backflow rate and intrastage backflow rate, the latter being a new fluid-dynamic parameter introd

β¦ Synopsis
The equations describing solvent extraction equipment with differential backmixing have been applied to distillation columns. The results can be interpreted in terms of this type of backmixing but the existing correlations for the liquid phase Peclet numbers must be increased by a factor of eight.

SEVERAL investigations have shown that the performance of a distillation column appears to be a function of composition [1, 2]. This variation in performance has been observed for many different systems and column types, and the reason would appear to be one which is general to the process of rectif
