Available in PDF, EPUB and Kindle. Book excerpt: Cyclone separators have been described in detail and, although substantial research has been performed on solid / gas devices, the use of cyclones for gas / liquid separation has been comparatively ignored; this is particularly true for higher concentrations of liquid and for degassing applications. Consequently no generic models are available which will predict separation efficiency or pressure drop for all designs of cyclone. A novel design of axial flow cyclone called WELLSEP was examined for the purpose of degassing. This design was not believed to be optimal and no design criteria or performance prediction models were available for it. An experimental programme was therefore produced and executed to investigate changes in geometry and the affect of fluid dynamics. Changes to the length, vortex finder and swirl generator were examined first and then one design was selected and tested over a number of liquid flow rates, Gas Void Fractions (GVFs) and liquid extractions. Data was collected from the experiments which assisted in the development of semi-empirical models for the prediction of pressure drop and separation efficiency. These models could be used in the design of WELLSEP. Geometric and fluid dynamics changes have both been shown to influence the performance of the tested cyclone. The principal conclusions that have been drawn from this research are: " Of the tested designs, the design based upon a 30mm vortex finder diameter, settling chamber length of three times the diameter of the cyclone and a four start helix gave the optimum separation efficiency over the greatest range of conditions. 0 The separation efficiency is affected by the superficial liquid velocity and the liquid extraction but not the GVF." The dimensionless pressure drop coefficient (Euler number) is a function of liquid extraction and GVF. It may also be a function of the superficial liquid velocity but it is unproven by this research.

Available in PDF, EPUB and Kindle. Book excerpt: This book has been conceived to provide guidance on the theory and design of cyclone systems. Forthose new to the topic, a cyclone is, in its most basic form, a stationary mechanical device that utilizes centrifugal force to separate solid or liquid particles from a carrier gas. Gas enters near the top via a tangential or vaned inlet, which gives rise to an axially descending spiral of gas and a centrifugal force field that causes the incoming particles to concentrate along, and spiral down, the inner walls of the separator. The thus-segregated particulate phase is allowed to exit out an underflow pipe while the gas phase constricts, and - in most separators - reverses its axial direction of flow and exits out a separate overflow pipe. Cyclones are applied in both heavy and light industrial applications and may be designed as either classifiers or separators. Their applications are as plentiful as they are varied. Examples include their use in the separation or classification of powder coatings, plastic fines, sawdust, wood chips, sand, sintered/powdered meta!, plastic and meta! pellets, rock and mineral cmshings, carbon fines, grain products, pulverized coal, chalk, coal and coal ash, catalyst and petroleum coke fines, mist entrained off of various processing units and liquid components from scmbbing and drilling operations. They have even been applied to separate foam into its component gas and liquid phases in recent years.

Book excerpt: The paper considers the secondary-flow in a liquid-gas mixture in a cyclone separator. By means of a momentum integral method, an engineering approximation to the secondary (heavy fluid) flow rate is obtained which makes use of an experimental velocity profile determined by ter Linden. This flow rate approximation is physically realistic and is partially verified in the laboratory. Tests were run on a separator to determine the effect of the variation of certain operating conditions and geometric factors on the separation of a liquid-gas mixture. The effect of these variations on the efficiency of separation and pressure drop across the separator as functions of the Reynolds and Weber numbers is presented. (Author).

This book was released on 2013 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cyclonic separation is a method of removing particulates from an air, gas or liquid stream, without the use of filters, through vortex separation. Rotational effects and gravity are used to separate mixtures of solids and fluids. A high speed rotating (air) flow is established within a cylindrical or conical container called a cyclone. Air flows in a helical pattern, beginning at the top (wide end) of the cyclone and ending at the bottom (narrow) end before exiting the cyclone in a straight stream through the center of the cyclone and out the top. Larger (denser) particles in the rotating stream have too much inertia to follow the tight curve of the stream, and strike the outside wall, then falling to the bottom of the cyclone where they can be removed. Cyclone separators have been used successfully in cement; agro; oil and various other industries. Its simple design and easy constructability make them very popular. This work is aimed for utilization by researchers, industrialists' and traditional businesses. Apart from this it will be especially relevant and useful for the students of Metallurgy, Mining, Mechanical engineering and Chemical engineering for carrying out research.

Available in PDF, EPUB and Kindle. Book excerpt: Vapor Liquid Separation Author Contact: Ronald J. Robichaux 1522 Savannah Drive, Garland, Texas 75041 E-mail: [email protected] My experience with separators led me to compile design information for the precise design of this type of equipment. These devices seem simple in their operations. However I have seen a number of them fail to provide the performance required in the process. Working with consultants, their many suggestions and rules of thumb to resolve the issues, has left me with concern as to how to best approach a design for a proper operating separator. I studied the works of many Engineers and designers and collected information from all the manufacturers I worked with in designing separators for my projects. I have read and collected many articles on the subject of separator design. In 1984 I had the opportunity to accept a position with Perry Equipment Corporation in Mineral Wells, Texas. The range of designs, research efforts and field trouble shooting left me with the understanding that "rules of thumb" are useful in a limited set of circumstances. Fortunately for the industry these set of circumstances are sufficient at about 75 to 90 percent of the time. One of the tasks I was given, while in their employ, was to attempt to place a scientific approach as to why these devices proved so successful in most situations, but failed in other situations. In order to develop a better understanding of the design parameters I wanted to know the physical properties of the fluids and their effect associated with separator failures and efficiencies.

Book excerpt: This practical guide is designed to help engineers and operators develop a "feel" for selection, specification, operating parameters, and trouble-shooting separators; form an understanding of the uncertainties and assumptions inherent in operating the equipment. The goal is to help familiarize operators with the knowledge and tools required to understand design flaws and solve everyday operational problems for types of separators. The most important gas/liquid separations that take place in oil field operation have been investigated. An inventory has been made of the conditions under which the separations have to take place and which requirements have to be fulfilled. The presently available separator types have been evaluated with respect to the suitability to fulfil the requirements listed above. It appeared that many separator types were not specifically designed for high pressure gas/liquid separation (rather for either atmospheric gas/liquid or high pressure gas/dust separation). It also appeared that in many cases the behaviour of the separator could not be reliably predicted under the conditions of the practical application.

Available in PDF, EPUB and Kindle. Book excerpt: It is with great pleasure and satisfaction that we introduce this volume which comprises the papers accepted for the 4th International Conference on Hydrocyclones held in Southampton from 23rd to 25th September 1992. As the name implies, this is the fourth Conference in the series, with the previous ones held in Cambridge in 1980, Bath in 1984 and Oxford in 1987. The papers cover a wide span of activities, from fundamental research to advances in industrial practice and, as in the earlier volumes, make a significant contribution of lasting value to the technical literature on hydrocyclones. Hydrocyclones continue to widen their appeal to engineers; besides their traditional role in mineral processing they now attract a lot of attention in chemical engineering, the oil and gas industry, power generation, the food industry, textiles, metal working, waste water treatment, pharmaceuticals, biotechnology and other industries. The reason for this continuously increasing attention is, as David Parkinson (General Manager of Conoco (UK)) said recently, that" ... a hydrocyclone is an engineering dream, a machine with no moving parts." Yet as this Volume clearly shows, the hydrocyclone can do so many things and do them well, whether the application is in solid-liquid, liquid-liquid or liquid-gas separation.

Download or read book Optimizing the Efficiency of Cylindrical Cyclone Gas liquid Separators for Field Applications written by Adedeji Adebare and published by . This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Problems associated with the use of compact cylindrical cyclone gas/liquid (CCGL) separators can be attributed to two physical phenomena: gas carry-under and liquid carryover(LCO). Inadequate understanding of the complex multiphase hydrodynamic flowpattern inside the cylindrical separator has inhibited complete confidence in its designand use, hence the need for more research. While many works have been done with a fixed inlet slot to predict the operational efficiency of the cyclone separator, very little is known about how separator performance can be influenced due to changes in fluid properties. During the operations of the CCGLseparator the complex flow situations arising from severe foaming within the separator has not been addressed. Also the effects of emulsion formation under three phase flow conditions on the properties of cyclone separators are yet to be studied. An understanding of liquid holdup and hydrodynamic nature of flow in a compact separator under zero net liquid flow (ZNLF) and zero net gas flow (ZNGF) conditions is necessary in many field applications, especially for the prediction of LCO and in the design of the CCGL separators. Also, ZNLF holdup is an important parameter inpredicting bottom-hole pressures in pumping oil wells. This research investigated the effects of fluid properties such as density, foam and emulsion formation on ZNLF, zero net gas flow ZNGF, and LCO in compact cyclone separators; this was achieved by replacing water, which is the conventional fluid used as the liquid medium in many previous research efforts with a foamy oil while maintaining air as the gas phase. Variable-inlet-slots that regulate the artificial gravity environment created by the separator were used to check for improved separator performance. Also experiments to check separator response to a range of water-cut in three-phase flow were performed. All experiments were carried out under low constant separator pressures. The ZNLF holdup is observed to decrease as the density of the fluid medium decreases. Varying the inlet slot configurations and recombination points does not haveany effect on the ZNLF holdup when changes in density of the liquid phase occur. Comparisons with previous work show that there exists a wide variation in the LCO operational envelope when severe foaming occurs in the CCGL separator. At high water cut (greater than 30%), the separator LCO performance was observed to be normal. However, at water-cut below 30%, LCO was initiated much earlier ; this is attributed to severe foaming in the CCGL separator.

Book excerpt: The paper considers the separation and containment of a liquid-gas mixture in a closed cyclone separator. A set of performance curves giving the measure of containment as a function of Reynolds number for various separator geometries is presented. Special attention is given to the effect of geometric factors on the development of secondary flows within the separator, and results are presented which give the pressure drop across the separator as a function of Reynolds numbers for various modes of operation.
