Feed Pretreatment for Binary Distillation Efficiency Improvement

摘要

In this paper we discuss thermodynamic efficiency for cases where two feeds of the same composition but different enthalpy are fed to a binary distillation column. We present a quick method to determine for each of the feeds whether it should be a saturated liquid or vapor or two-phase. This study provides a process designer with a quick and reliable method for selecting thermodynamically efficient configurations through preconditioning of the feed streams and addition/removal of heat from intermediate locations of a binary distillation column.
