Distillation introduction ppt

This week we will learn how to perform a distillation, a method for purifying liquids. It is particu-larly well suited for high purity separations since any degree of separation can be The residue from the atmospheric distillation column generates two side streams, light and heavy vacuum gas oils, and vacuum residue from the bottom. About 80% of the refineries operating in the United States have a vacuum distillation unit (VDU), a secondary processing unit consisting of vacuum distillation columns. Valve arrangement offer more flexibility to cope with wider rangeof liquid and vaporflow rates. [1]. In the ‘once-through’ design, the DISTILLATION Distillation is a process in which a liquid or vapour mixture of two or more substances is separated into its component fractions of desired purity, by theapplication and removal of heat. The petroleum refining process is the separation of the different hydrocarbons present in the crude oil into useful fractions and the conversion of some of the The underpinning physical and thermodynamic phenomena of distillation result in its energy intensity.

Petroleum refining begins with the distillation, or fractionation, of crude oils into separate hydrocarbon groups. Liquid-liquid extraction (also known as solvent extraction) involves the separation of the constituents (solutes) of a liquid solution by contact with another insoluble liquid. Unique and distinctive flavour of the final spirits depends on their quantity and quality. It is composed of a complex mixture of acetic acid, methyl alcohol, acetone and a number of other chemicals.

Introduction to Multicomponent Distillation In industry, most of the distillation processes involve with more than two components. Fractional distillation is a process by which components in a chemical mixture are separated into different parts (called fractions) according to their different boiling points. Extractive distillation is one of the leading distillation processes for the separation of minimum- or maximum-boiling azeotropes and low-relative-volatility mixtures. Fractional distillation is the process of taking a chemical mixture and using heat to separate out the various components in that mixture.

This type of distillation is approximated by the laboratory A. The vapors condense in a cold collecting test tube to form a brownish liquid. Unlike azeotropic distillation, the entrainer is fed at a different location than the main mixture to be separated, inducing an extractive section within the column. For others, however, quantum cryptography also includes other applications of quantum mechanics related to cryptography, such as quantum secret sharing. Some of these compounds have important uses as medicines, perfumes, flavoring agents etc. The feed stream and a recycle stream from the second column are fed into the first column. Crude oil is made up of a mixture of hydrocarbons, and the distillation process aims to separate this crude oil into broad categories of its component hydrocarbons, or "fractions. Distillation appears to have been practiced throughout ancient times. Crude Because reactive distillation reduces the number of equip-ment and the number of connections between equipment it will havelessdiffusivegasemissions. Continuous distillation is a thermodynamically efficient method of producing large amounts of material of constant composition.


Full documentation can be found in the extensive on-line manuals, available via the Start Menu in Windows. When people, processes and technology work Distillation of crude oil is carried out in two units, first in an Atmospheric Distillation Unit (also known as Crude Distillation Unit, CDU), with further processing of the residue from atmospheric distillation in the Vacuum Distillation Unit (VDU), as illustrated in Figure 4. Reactive Distillation We offer full R&D, engineering design and support for your reactive distillation project. Sieve tray, is the most common arrangement used. CHE-396 Senior Design (Distillation) 3 Introduction This report examines the distillation process. Representative Sample Dissect both deer. Distillation is a common wet-chemical technique for separating organic compounds based on differences in boiling points. In this case simple distillation would not be enough to fully separate the two liquids. Distillation design and operation need to be based on a clear understanding of these phenomena, “energy efficiency” and the process economics of distillation processes and the associated energy-supply processes. 11 The Problem of Designing Distillation Units 38 2.


We cover the cycle of vaporization, cooling, and condensation that is the basis for the process. Fractional Distillation (Adapted from Mohrig, pp. This leads to the introduction of bound entangled states. A liquid stream containing several components is partially for more subscribe my channel 😄😃 !! This feature is not available right now. Figure 1. Lienhard,1,⁄ Mohamed A. 0 Introduction 1. how distillation systems are designed is essential. Figure 4 depicts the structure of the distillation process by dividing the vapor/liquid equilibrium information into three distinct zones of process and equipment requirements: stripping, rectifying and dehydration. com, find free presentations research about Steam Distillation PPT Distillation Experiment CHM226 Background The distillation process is a very important technique used to separate compounds based on their boiling points.


Mashue and H. Distillation is the process of separating the components or substances from a liquid mixture by using selective boiling and condensation. The process is the same; the difference is mainly one of iteration. , lower boiling point) components out of the mixture. This method can also be used in identifying a substance by determining its boiling point. Distillation Introduction Introduction Since organic compounds do not usually occur in pure condition in nature, and are accompanied by impurities when synthesized, the purification of materials forms an important part of laboratory work in chemistry. " Crude oil is first heated and then put into a distillation column, also known as a still, where different products boil off and are recovered at different temperatures. PETROLEUM REFINING AND THE PROD UCTION OF ULSG AND ULSD OCTOBER 24, 2011 Page 1 1. 1 . Fogler (UMich) Number of Trays q Website devoted to reactive distillation or Stages Factors Affecting Design Operation Crossword q McCabe-Thiele r Distillation column design using the McCabe-Thiele method (Stage 1 Other Introduction Although many people have a fair idea what distillation means, the important aspects that seem to be missed from the manufacturing point of view are that: distillation is the most common separation technique it consumes enormous amounts of energy, both in terms of cooling and heating requirements it can contribute to more than 50% Introduction to multicomponent distillation Most of the distillation processes deal with multicomponent mixtures Multicomponent phase behaviour is much more complex – A free PowerPoint PPT presentation (displayed as a Flash slide show) on PowerShow.

In Simple distillation condenses the liquid once, so the boiling points of the two liquids must be far apart to make it efficient. distillation introduction ppt
