ABSTRACT
In the column model discussed in Chapters 3 through 13, the internal liquid and vapor flows were considered only from the standpoint of their effect on the thermodynamic performance of the column. The performance parameters that were investigated included quantities such as compositions, temperatures, pressures, enthalpies, and K-values. The column was assumed capable of physically handling any liquid or vapor flow rate, regardless of hydraulic effects or pressure drops. The only flow limitations that were taken into account involved minimum reflux ratio and conditions under which the liquid or vapor “dried up,” or approached zero flow in certain parts of the column.
