Introduction

The concept of an equilibrium stage in distillation is based on the assumption that the vapour leaving the

stage is in equilibrium with the liquid leaving the same stage. The use of this concept in the design of distillation columns requires a description of how the components of a multicomponent mixture distribute between the two phases in equilibrium. This description is provided by phase equilibrium thermodynamics.

The equilibrium relationship for any component i in an equilibrium stage is defined in terms of the

Global warming is a huge problem which will significantly affect every country in the world. Many people all over the world are trying to do whatever they can to help combat the effects of global warming. One of the ways that people can fight global warming is to reduce their dependence on non-renewable energy sources like oil and petroleum based products.
