Fractional Distillation - The principle of fractional distillation is based on the establishment of a large number of theoretical vaporization-condensation cycles (theoretical plates): the apparatus of a simple distillation is modified by inserting a fractionating column between the distillation flask and the distillation head, Figure 4. the yield is greater than if several separate simple distillations had been done. Note however that even in a fractional distillation, some material is lost to evaporation and some is left behind in the apparatus ("hold-up"). Distillation is a sacrificial process in that some material is always lost, no Applications of batch distillation • Limits of separation. Subsequent distillations are needed. • When relatively smaller amount of feed have to be purified batch distillation is more economic than continuous distillation processes. • When composition of feed changes frequently, but distillation have to be performed in the same unit. Introduction to Column Distillation distillation cascade; note that the first column (or the feeding flash column) is denoted as "3" the higher-pressure column is denoted as "2" the lower-pressure column is denoted as "4" Note that a pump or a compressor is used to increase the pressure of the vapour product . 6 Figure 3.1: The configuration of a simple distillation cascade The Distillation PPT and PDF Download: Distillation is the method of separating the elements or substances from a liquid mixture by condensation and selective evaporation. Distillation might lead to basically full separation (nearly pure components), or it should be a partial separation that will enhance the concentration of designated elements or extraction, leaching , distillation, humidification, drying and evaporation. Objectives: To give the students a application of diffusion theory to simple mass transfer problems. Analysis of chemical engineering unit operations involving mass transfer. Design principles for mass transfer equipment. Solids/Liquids separation processes. liquids ORGANIC LABORATORY TECHNIQUES 10 10.1 DISTILLATION NEVER distill the distillation flask to dryness as there is a risk of explosion and fire. The most common methods of distillation are simple distillation and fractional distillation. Simple distillation can be used when the liquids to be separated have boiling points that are quite different. Distillation Process . Distillation separates . two . or more liquid components in a mixture using the principle of relative volatility or boiling points. The greater the difference in relative. volatility th. e greater the nonlinearity . and . the easier it is to separate the mixture using . distillation. The process involves production of Distillation lecture 1. Distillation Dr. Nasir Abbas 2. Definition • Distillation is a method of separating mixtures based on differences in volatility (vapour pressure) of the components in a boiling liquid mixture • It is a unit operation, or a physical separation KLM Technology Group Distillation History Practical Solutions A Kerosene Hydrotreater built in 1952 had one bubble cap per tray on the Stripper Tower, which was one meter in This introduction of Distillation is provided by Kolmetz.Com which is a chemical engineering web By 1976, distillation accoun
