Normalistas No. 800, C.P. 44720 Guadalajara, Jalisco, Mexico; [email protected] (E.-E.M.); [email protected] (R.-P.M.) * Correspondence: [email protected] (P.-d.l.R.J.D.); [email protected] (P.-R.R.); Tel.: +33-33455200 (P.-d.l.R.J.D.) Received: 23 March 2019; Accepted: 6 May 2019; Published: 14 May 2019 Abstract: In this study, a new process of continuous horizontal distillation at a pilot level is presented. It was applied for the first time to the rectification of an ordinario fraction obtained industrially. Continuous horizontal distillation is a new process whose design combines the benefits of both distillation columns, in terms of productivity and energy savings (50%), and distillation stills in batch, in terms of the aromatic complexity of the distillate obtained. The horizontal process of continuous distillation was carried out at the pilot level in a manual mode, obtaining five accumulated fractions of distillate that were characterized by gas chromatography (GC-FID). The tequila obtained from the rectification process in this new continuous horizontal distillation process complies with the content of methanol and higher alcohols regulated by the Official Mexican Standard (NOM-006-SCFI-2012). Continuous horizontal distillation of tequila has potential energy savings of 50% compared to the traditional process, besides allowing products with major volatile profiles within the maximum limits established by the regulation for this beverage to be obtained. -

Modelling of Crude Oil Distillation
Modelling of Crude Oil Distillation Modellering av råoljedestillation JENN Y BEATRIC E SOUC K K T H C h em i ca l S ci en c e and E n gi n e e r i n g Master’s Thesis in Chemical Engineering Stockholm, Sweden 2012 " One never notices what has been done; one can only see what remains to be done" (Marie Curie, 1867-1934) 1 Sammanfattning Under de föhållanden som reservoarens miljö erbjuder, definieras en petroleumvätska av dess termodynamiska och volymetriska egenskaper och av dess fysikalisk-kemiska egenskaper. För att korrekt simulera bearbetningen av dessa vätskor under produktion, deras beteende modelleras från experimentella data Med tillkomsten av nya regler och oflexibilitet som finns på tullbestämmelser vid gränserna idag, har forskningscenter stora svårigheter att få större mängder prover levererade. Av den anledningen, trots att det finns flera metoder för att karakterisera de olika komponenterna av råolja, tvingas laboratorier att vända sig mer och mer till alternativa analysmetoder som kräver mindre provvolymer: mikrodestillation, gaskromatografi, etc. Mikrodestillation, som är en snabb och helt datoriserad teknik, visar sig kunna ersätta standarddestillation för analys av flytande petroleumprodukter. Fördelar med metoden jämfört med standarddestillering är minskad arbetstidsåtgång med minst en faktor 4. Därtill krävs endast en [24] begränsad provvolym (några mikroliter) i jämförelse med standarddestillation. Denna rapport syftar till att skapa en enkel modell som kan förutsäga avkastningskurvan av fysisk destillation, utan att använda mikrodestillationsteknik. De resultat som erhölls genom gaskromatografiska analyser möjliggjorde modelleringen av det vätskebeteendet hos det analyserade provet. Efter att ha identifierat och behandlat praktiskt taget alla viktiga aspekter av mikro destillation genom simuleringar med PRO/II, fann jag att, oberoende av inställningen och den termodynamiska metod som används, det alltid finns stora skillnader mellan simulering och mikro destillation. -

Computer Simulation of a Multicomponent, Multistage Batch Distillation Process
COMPUTER SIMULATION OF A MULTICOMPONENT, MULTISTAGE BATCH DISTILLATION PROCESS By BRUCE EARL BAUGHER /J Bachelor of Science in Chemical Engineering Oklahoma State University Stillwater, Oklahoma 1985 Submitted to the Faculty of the Graduate College of the Oklahoma State University in partial fulfillment of the requirements for the Degree of MASTER OF SCIENCE July, 1988 \\,~s~ ~ \'\~~ B~~~to' <:.o?. ·;)._, ~ r COMPUTER SIMULATION OF A MULTICOMPONENT, MULTISTAGE BATCH DISTILLATION PROCESS Thesis Approved: Thesis Advisor U.bJ ~~- ~MJYl~ Dean of the GradU~te College ABSTRACT The material and energy balance equations for a batch distillation column were derived and a computer simulation was developed to solve these equations. The solution follows a modified Newton-Raphson approach for inverting and solving the matrices of material and energy balance equations. The model is unique in that it has been designed to handle hypothetical hydrocarbon components. The simulation can handle columns up to 50 trays and systems of up to 100 components. The model has been used to simulate True Boiling Point (TBP) diagrams for a variety of crude oils. This simulation is also applicable to simple laboratory batch distillations. The model was designed to accurately combine data files to simulate actual crude blending procedures. The model will combine files and calculate the results quickly and easily. The simulation involves removing material from the column at steady-state. The removal fraction is made small enough to approach continuity. This simulation can be adapted for use on microcomputers, although it will require extensive computation time. ACKNOWLEDGMENTS It has been a great pleasure to work with my thesis advisor, Dr. -
Laboratory Rectifying Stills of Glass 2
» LABORATORY RECTIFYING STILLS OF GLASS 2 By Johannes H. Bruun 3 and Sylvester T. Schicktanz 3 ABSTRACT A complete description is given of a set of all-glass rectifying stills, suitable for distillation at pressures ranging from atmospheric down to about 50 mm. The stills are provided with efficient bubbling-cap columns containing 30 to 60 plates. Adiabatic conditions around the column are maintained by surrounding it with a jacket provided with a series of independent electrical heating units. Suitable means are provided for adjusting or maintaining the reflux ratio at the top of the column. For the purpose of conveniently obtaining an accurate value of the true boiling points of the distillates a continuous boiling-point apparatus is incor- porated in the receiving system. An efficient still of the packed-column type for distillations under pressures less than 50 mm is also described. Methods of operation and efficiency tests are given for the stills. CONTENTS Page I.

Distillation Handbook
I distillation terminology To provide a better understanding of the distillation process, the following briefly explains the terminology most often encountered. SOLVENT RECOVERY The term "solvent recovery" often has been a somewhat vague label applied to the many and very different ways in which solvents can be reclaimed by industry. One approach employed in the printing and coatings industries is merely to take impure solvents containing both soluble and insoluble particles and evapo- rate the solvent from the solids. For a duty of this type, APV offers the Paraflash evaporator, a compact unit which combines a Paraflow plate heat exchanger and a small separator. As the solvent ladened liquid is recirculated through the heat exchanger, it is evaporated and the vapor and liquid separated. This will recover a solvent but it will not separate solvents if two or more are present. Afurther technique is available to handle an air stream that carries solvents. By chilling the air by means of vent condensers or refrigeration equipment, the solvents can be removed from the condenser. Solvents also can be recovered by using extraction, adsorption, absorption, and distillation methods. S 0 LV E NT EXT R ACT I0 N Essentially a liquid/liquid process where one liquid is used to extract another from a secondary stream, solvent extraction generally is performed in a column somewhat similar to a normal distillation column. The primary difference is that the process involves two liquids instead of liquid and vapor. During the process, the lighter (i.e., less dense) liquid is charged to the base of the column and rises through packing or trays while the more dense liquid descends. -
Building a Home Distillation Apparatus
BUILDING A HOME DISTILLATION APPARATUS A Step by Step Guide Building a Home Distillation Apparatus i BUILDING A HOME DISTILLATION APPARATUS Foreword The pages that follow contain a step-by-step guide to building a relatively sophisticated distillation apparatus from commonly available materials, using simple tools, and at a cost of under $100 USD. The information contained on this site is directed at anyone who may want to know more about the subject: students, hobbyists, tinkers, pure water enthusiasts, survivors, the curious, and perhaps even amateur wine and beer makers. Designing and building this apparatus is the only subject of this manual. You will find that it confines itself solely to those areas. It does not enter into the domains of fermentation, recipes for making mash, beer, wine or any other spirits. These areas are covered in detail in other readily available books and numerous web sites. The site contains two separate design plans for the stills. And while both can be used for a number of distillation tasks, it should be recognized that their designs have been optimized for the task of separating ethyl alcohol from a water-based mixture. Having said that, remember that the real purpose of this site is to educate and inform those of you who are interested in this subject. It is not to be construed in any fashion as an encouragement to break the law. If you believe the law is incorrect, please take the time to contact your representatives in government, cast your vote at the polls, write newsletters to the media, and in general, try to make the changes in a legal and democratic manner. -
Batch Distillation of Spirits: Experimental Study and Simulation
Research article Received: 5 April 2018 Revised: 11 January 2019 Accepted: 15 January 2019 Published online in Wiley Online Library (wileyonlinelibrary.com) DOI 10.1002/jib.560 Batch distillation of spirits: experimental study and simulation of the behaviour of volatile aroma compounds Adrien Douady,1 Cristian Puentes,1 Pierre Awad1,2 and Martine Esteban-Decloux1* This paper focuses on the behaviour of volatile compounds during batch distillation of wine or low wine, in traditional Charentais copper stills, heated with a direct open flame at laboratory (600 L) and industrial (2500 L) scale. Sixty-nine volatile compounds plus ethanol were analysed during the low wine distillation in the 600 L alembic still. Forty-four were quantified and classified according to their concentration profile in the distillate over time and compared with previous studies. Based on the online re- cording of volume flow, density and temperature of the distillate with a Coriolis flowmeter, distillation was simulated with ProSim® BatchColumn software. Twenty-six volatile compounds were taken into account, using the coefficients of the ‘Non- Random Two Liquids’ model. The concentration profiles of 18 compounds were accurately represented, with slight differences in the maximum concentration for seven species together with a single compound that was poorly represented. The distribution of the volatile compounds in the four distillate fractions (heads, heart, seconds and tails) was well estimated by simulation. Fi- nally, data from wine and low wine distillations in the large-scale alembic still (2500 L) were correctly simulated, suggesting that it was possible to adjust the simulation parameters with the Coriolis flowmeter recording and represent the concentration pro- files of most of the quantifiable volatile compounds. -

In this paper we develop a measure of variety, based on Weitzman's maximum likelihood procedure. This measure is based on the distance between products, and indicates the degree of differentiation of a product population. We propose a generic method, which permits to regroup the products with very similar characteristics values before choosing randomly the product models to be used to calculate Weitzman's measure.
