Difference Between Evaporation and Distillation

Introduction

The main difference between evaporation and distillation is that evaporation is a process that involves a change in the state of matter while distillation is a process of separation. Both these processes are used for various purposes. While the vaporization in evaporation occurs below the boiling point, the vaporization in distillation occurs at the boiling point. In this article, let us learn more differences between distillation and evaporation.

Evaporation vs Distillation

Evaporation Distillation The process of converting a liquid to a gas under the influence of heat is called evaporation. The process of obtaining gas or vapour from liquids through boiling and condensing to liquid is called distillation. Evaporation is a slow and gradual process. The process of distillation is quick and rapid. It occurs at the surface It doesn’t only occur at the surface It is used for removing impurities and for obtaining concentrated products. It is used for the purification of liquids from the mixtures and for separation also. In evaporation, no liquid bubbles are formed at the boiling point. In condensation, liquid bubbles are formed at the boiling point. In evaporation, the liquid vaporizes below the boiling point. In distillation, the liquid vaporizes at the boiling point.

From the listed differences between distillation and evaporation, we can conclude that the main difference between them lies at the boiling point. Evaporation happens below a liquid’s boiling point when distillation happens right at the boiling point. Both systems are based on certain variables that may be identical, but all in all, they are very distinct.
