Abstract

The definition of Murphree point efficiency in distillation is critically examined. Characteristics of Standards stage efficiency definition are utilized to define a new point efficiency on a plate in a column. This new definition was shown to be consistent and symmetrical. for crossflow on a plate, the proposed point efficiency was found to be equal to Standart stage efficiency subject to only the assumption of a uniform value of the proposed point efficiency over the whole plate.
