Distillation is the process of heating a liquid solution, or a liquid-vapor mixture, to derive off a vapor and then collecting and condensing this vapor. In the simplest case, the products of a distillation process are limited to an overhead distillate and a bottoms, whose compositions differ from that of the feed. Distillation is one of. necessary components along with distillation calculations. Distillation is a process that separates two or more components into an overhead distillate and bottoms. The bottoms product is almost exclusively liquid, while the distillate may be liquid or a vapor or both. The separation process requires three things. First, a second. Aug 11, This is a revised version of an article accepted for publication in the Encyclopedia of Separation. Science by Academic Press Ltd. (submitted in. ). This article gives some of the basics of distillation theory and its purpose is to provide basic understanding and some tools for simple hand calculations of.
Most of the processes in chemical industry are involved in purifying components. As a consequence, a large part of the energy use in many industrial sectors can be attributed to separation processes. Distillation is the dominant separation technology in chemical industries despite its huge energy consumption. Distillation. Distillation refers to the physical separation of a mixture into two or more fractions that have different boiling points. The general objective is to separate substances having different vapor pressures at any given temperature. If a liquid mixture of two volatile materials is heated, the vapor that comes out with a higher. Certain fundamental principles are common to all distilling systems. Modern distillation systems are multi-stage, continuous, countercurrent, vapor-liquid contacting systems that operate within the physical laws that state that different materials boil at different temperatures. Represented in Figure 1 is a typical distillation.
FROM a design standpoint, the field of distillation can be divided into two broad categories. Under such division, one category would contain those units where the feed stream is to be divided into a multiplicity of cuts. Highly effi- cient separation between cuts is normally not required. Examples of this type of distillation are. DISTILLATION IS ▻ a process in which a liquid or vapor mixture of two or more substances is separated into its component fractions of desired purity. ▻ based on the fact that the vapor of a boiling mixture will be richer in the components that have lower boiling points. ▻ a consumer of enormous amounts of energy.
