Other Abstract<正> A graphical design method is proposed for estimating the number of theoretical contact stages for ternary separation operations under conditions of nonideality. The required thermodynamic data are arranged for constant pressure operations to give the equilibrium relationship and enthalpies of the vapour and liquid mixtures. Graphical constructions are made on charts containing these data starting from material and enthalpy operating points, for which generalized formulae are given, valid for such separation devices as the rectifier, stripper, absorber, distillation column, with any number of feeds and/or side drawoffs.The method takes into account nonidealities arising from changing equilibrium constants and changing molal flow rates with composition, and is rigorous to the extent of the limit of readability of the chart. In general the usual algebraic computation for a theoretical stage is reduced to the construction of three straight lines.A discussion is given on the trial-and-error procedure involved in assigning proper terminal conditions to actual design problems for ternary separation operations from the viewpoint of analysis of variables. The condition existing at the feed plate is described in relation both to compositions of the streams in the adjacent sections and to the thermal condition of the feed.The graphical construction and the discussion on variables are illustrated with examples on the separation of liquid air, including the case of a double distillation column.
