Ethanol distillation : the fundamentals 269 Chapter 18 Ethanol distillation : the fundamentalsR. Katzen, Madson and Moon, JrKATZEN International, Inc., Cincinnati, Ohio, USAF undamentals of a distilling systemCertain fundamental principles are common toall distilling systems. Modern distillation systemsare multi-stage, continuous, countercurrent,vapor-liquid contacting systems that operatewithin the physical laws that state that differentmaterials boil at different in Figure 1 is a typical distillationtower that could be employed to separate anideal mixture. Such a system would contain thefollowing elements:a. a feed composed of the two components tobe separated,b. a source of energy to drive the process (inmost cases, this energy source is steam, eitherdirectly entering the base of the tower ortransferring its energy to the tower contentsthrough an indirect heat exchanger called areboiler),c.
Analysis of the ethanol-water distillation ... Considerations in preliminary design The engineer, given the assignment of designing ... For an ethanol stripper/rectifier, there are two operating lines: one for the rectification section and one for the stripping section. The operating lines represent the locus
