A Study on the Batch Distillation Operation Method for Separating Heat-Sensitive Materials by Recycling Reboiler Holdup I. Basic Principle and Mathematical Simulation

Based on the theoretical analysis ot thermal stability of heat sensitive ma- terials and reliability degradation index of separation equipment, a new type of operation method of batch distillation by recycling reboiler holdup is investigated with a view to reducing the residential time ot thermally unstable substances in the heat zone of the column. A rule for choosing proper separation column according to the different thermal stability of heat sensitive materials has been proposed. An overall theoretical analysis of this operating system is made in this paper.
