Mass transfer in a packed extractive distillation column

Abstract

The kinetics of mass transfer in the extractive distillation of the benzene–heptane mixture (which imitates the catalytic reforming product mixture) in the presence of N-methylpyrrolidone as the separating agent has been investigated. The separating agent exerts an effect on the overall efficiency of the process. The partial heights of transfer units in the vapor and liquid have been determined, and equations for calculating these parameters have been set up.
