Transport Processes and Separation Process Principles (Includes Unit Operations) Fourth Edition

14.1. INTRODUCTION AND CLASSIFICATION OF MECHANICAL–PHYSICAL SEPARATION PROCESSES

14.1A. Introduction

In Chapters 10 and 11, gas–liquid and vapor–liquid separation processes were considered. These separation processes depended on molecules diffusing or vaporizing from one distinct phase to another phase. In Chapter 12, liquid–liquid separation processes were discussed, in which the two liquid phases are quite different chemically, leading to separation on a molecular scale according to physical–chemical properties. Also in Chapter 12, we considered liquid–solid leaching, ion-exchange, and adsorption separation processes. Again, differences in the physical–chemical properties of the molecules lead to separation on a molecular scale. In Chapter ...
