Abstract

A study on the influence of mass transfer on distillation column design is presented. The column design equations incorporating mass transfer effects are similar to the conventional design equations and are as easy to solve numerically. Evidence that the boundaries in nonequilibrium ternary distillation processes are the longest composition trajectories in a given region of composition space are given. The minimum energy design for a specified separation can be defined by the shortest feasible stripping trajectory. These properties of the distillation trajectories corresponding to boundaries and to minimum boilup/reflux are the basis for optimization based algorithms that can be used for the determination of energy efficient distillation processes when mass transfer effects are important. This is an abstract of a paper presented at the 2007 AIChE Annual Meeting (Salt Lake City, UT 11/4-9/2007).
