TY - JOUR. T1 - Separation of water - Acetic acid mixtures by cyclic distillation. AU - Pătruț, Cătălin. AU - Udrea, Elena Cătălina. AU - Bildea, Costin-Sorin. PY - 2018/1/1. Y1 - 2018/1/1. N2 - Acetic acid is a carboxylic acid, industrially produced for a large range of applications. All the processes include a water - acetic acid separation step which, due to the presence of a tangent pinch on the pure water end, is performed in practice through heterogeneous azeotropic distillation. The current paper compares the separation of the water - acetic acid mixture through conventional distillation, cyclic distillation, and azeotropic distillation with i-butyl acetate as entrainer. Cyclic distillation is a better technique compared to the conventional distillation. However, for applications in which the contamination of acetic acid with i-butyl acetate is allowed, the azeotropic distillation is economically a better candidate.. AB - Acetic acid is a carboxylic acid, industrially produced for a ...

In a pharmaceutical industry, batch extractive distillation (BED), a combination process between extraction and distillation processes, has been widely implemented to separate waste solvent mixture of acetone-methanol because of minimum-boiling azeotrope properties. Normally, water is used as solvent and semi-continues mode is proposed to improve purity of acetone. The solvent is charged into the BED column until the purity of a desired product is achieved. After the total reflux start-up period is ended, a dynamic optimization strategy is applied to determine an acetone distillate composition profile maximizing the weight of the distillate product (acetone). The acetone distillate composition profile is used as the set point of neural network model-based controllers: the neural network direct inverse model control (NNDIC) and neural network based model predictive control (NNMPC) in order to provide the acetone composition with the purity of 94.0% by mole within 9.5 hours. It has been found that ...

Acetone and methanol are organic solvents widely used in industry. Acetone with methanol forms a homogeneous minimum-boiling azeotrope which is not separable by conventional distillation processes. A common method for its separation is the extractive distillation in the presence of a selective solvent (such as water). In this paper, the use of an ionic liquid (1-ethyl-3-methylimidazolium trifluoro methanesulfonate [Emim][triflate]) for acetone-methanol separation by extractive distillation was designed. The aim of the design calculation was to obtain acetone with the purity of 99.5 mol % and methanol with the purity of above 99.0 mol %. Calculations were carried out in a proprietary program constructed in Matlab® by solving a set of material balances at individual theoretical stages of the distillation column combined with the vapor-liquid equilibrium (VLE) of the ternary system acetone-methanol-[Emim][triflate]. For the description of VLE of the above mentioned system, the NRTL equation was ...
If you want the best possible parting involving water from the required alcohol or spirit during distillation then you could surely obtain purer alcohols together with safe ethanol distillation column process. An easy container http://destillation.com distillation method might not exactly provide you with the desired outcomes therefore you may merely end up saddled having harmful alcoholic beverages that could be infused with toxic chemicals.. Even though the distillation method seems to be quite simple on paper, it is not merely a problem of boiling the fermented mash or perhaps mixture including water together with various other elements in addition to your selected grain, fruits, or even veggie. Since water vaporizes at above 100 degrees Celsius and also alcoholic beverages as well as ethanol vaporizes at around 78 degrees Celsius, it might seem like an easy method for merely boil the particular blend and look forward to the alcohol or ethanol to vaporize initially exactly where it is ...
What is Distillation Distillation is a way of separating substances which are mixed together. If you were to mix alcohol and water together you could separate the two substances by distillation. The process would work like this: -Heat the mixture when it reaches 78 °C the alcohol will boil. -When the alcohol boils it will turn to gas. -The gas will rise out of the mixture. Because water boils at 100 °C it remains a liquid. -The gaseous alcohol is then trapped and when the temperature is lowered it will turn back into a liquid. Observe distillation demonstration.

Garden sage (Salvia officinalis L.) is a medicinal, culinary, ornamental, and essential oil plant with a wide range of ecological adaptation. Garden sage essential oil traditionally is extracted by steam distillation from the above-ground biomass and has widespread applications as an aromatic agent in the food and pharmaceutical industries as well as in perfumery and cosmetics. The hypothesis of this study was that the steam distillation time (DT) may significantly affect essential oil yield and composition of garden sage and, therefore, DT could be used as a tool to obtain oil with different composition. Therefore, the objective was to evaluate the effect of various steam DTs (1.25, 2.5, 5, 10, 20, 40, 80, and 160 minutes) on garden sage oil yield and composition. Most of the oil in the garden sage dry herbage was extracted in 10-minute DT; extending DT up to 160 minutes did not significantly increase oil yields. Overall, 39 oil constituents were identified in the garden sage essential oil. ...

TY - CHAP. T1 - Dehydration of isopropanol by batch heteroazeotropic distillation with toluene as entrainer. AU - Nemeth, Bence. AU - Hegely, Laszlo. AU - Láng, P.. PY - 2018/1/1. Y1 - 2018/1/1. N2 - The dehydration of isopropanol (B) by batch heteroazeotropic distillation (BHAD) is studied by dynamic simulation. The mixture also contains methyl ethyl ketone (A) and toluene (E) as pollutants. The water (C) content of the feed (ca. 2 mass%) is much lower than that of the B-C azeotrope. B can be obtained as residue by conventional batch distillation (BD) under a very high reflux ratio and considerable loss of B, only. The loss of B can be considerably decreased by BHAD. Toluene, already present in the mixture, can be a suitable entrainer (E), since it forms a ternary heteroazeotrope with isopropanol and water. Dehydration is feasible by Mode II, Strategy A of BHAD, that is, the two liquid phases of the condensate are separated in a decanter, and the whole amount of E-rich phase is refluxed, while ...

While they may seem like a new trend people have been flavouring spirits almost as long as they have been distilling them. One of the earliest and most common uses of distilled alcohol was as medicine and it was thought that flavouring alcohol with herbs, berries, flowers and similar could have a positive effect on your health (positive for that time, anyway!).. In terms of more modern products, people are often confused at the difference between flavoured spirits, such as Absolut Vanilla or Bacardi Razz, and liqueurs. The easiest way to think if it is the difference in the amount of sugar - flavoured spirits tend to have no (or very little) added sugar, so youre basically tasting more of the actual spirit while liqueurs are much more heavily… sugared (if thats a word).. .. Also, while liqueurs tend to get their flavouring added to the spirit after distillation, some (but not all) flavoured spirits actually get their flavour during the distillation process, by putting the flavour (whether ...
G. Wcisło, N. Labak. Full text PDF. Summary. The aim of the study was to determine the impact of the frying process on the fractional composition of AME Biodiesel in comparison to the AME obtained from unused (fresh) animal fat. The fresh animal fat was divided into two portions. One was used for frying chips at 63oC for a period of 4 hours. The study showed the AME biodiesel produced from unused (pure) animal fat generally has better distillation properties. The temperatures at the start of distillation were similar for both of the AMEs. Within the 45-60% mid-range temperatures, the AME produced from the used cooking animal fat was characterized by higher distillation temperatures for the same volume of fuel. The largest differences were observed for the 85% and 95% distillation temperatures and the final temperature of the distillation process. This may testify to lower purity of the AME produced from the used cooking oil. In such a biofuel may consist less volatile mono-diglycerides or other ...
A distillate sampling adapter (Figure 1) installed following a condenser or distillation column can provide this important capability without the need for cumbersome, expensive, and often unreliable fraction collectors. The flow of the distillate is focused to drop into a 0.05 mL "hammock" that is positioned directly below the flow path. The sampling port, equipped with a vacuum tight valve, allows access to the hammock with a standard chromatographic syringe, through a septum. To sample the distillate, one simply positions the chromatographic syringe, preferably equipped with a blunt tipped needle, in the well of the hammock. It is a simple matter to withdraw samples as the distillation progresses. The sample can then be directly injected into the gas chromatograph or spectrometer, or injected into an autosampler vial for analysis later. Indeed, any analytical technique that is applicable for liquid samples ranging in volume from 1 to 50 microliters can be used to characterize the distillate. ...
The diluted ethanol solutions and fermentation broth (Saccharomyces cerevisiae) were separated by membrane distillation (MD). Hydrophobic macroporous (pore size 0.2 μm) capillary polypropylene membranes, Accurel PP V8/2 HF and Accurel PP S6/2, were used for these studies. The MD process can be successfully applied to remove the volatile components from the fermentation broth. Besides ethanol, propionic and acetic acids were moved from the broth to the distillate. Therefore, the course of the fermentation carried out in a membrane distillation bioreactor considerably accelerate its rate and increase the efficiency by a selective removal of fermentation products. It was found that the broth subjected to the separation did not affect the hydrophobic properties of the polypropylene membrane assembled in the MD modules ...

Optimization of the use of energy is of fundamental importance, particularly in view of the increasing tensions between energy supply and demand which the world now faces. Chemical processes in general, and distillation processes in particular, account for a significant fraction of the worlds energy usage. For example, distillation processes account for around 3% of the energy utilization in the US. There is thus a significant incentive to so design systems that energy utilization is minimized. Much progress has been made by the application of simple methods such as pinch technology (see for instance B. Linnhoff and R. Smith, Section 1.7 of the Heat Exchanger Design Handbook, also published by Begell House), but the problems encountered in complex distillation systems are such that a much higher level approach is needed. Both authors, Michael Georgiadis and Efstratios Pistikopoulos are from the Centre for Process Systems Engineering (CPSE) at Imperial College. CPSE is an international leader in the

Distillation does not produce alcohol, it merely concentrates it. To produce a distilled spirit you need to start with an alcoholic liquid (wash) to distil your spirit from. The majority of vodkas and all whiskies are distilled from a wash which is essentially beer made by fermenting cereal grains.
PRINCIPLE OF WORKING :. Flash distillation (or simple distillation) allows the separation from a feed solution of the compounds present in this solution by evaporation.. The more volatile compound is partially evaporated then, after condensation and cooling, collected separately from the solution; this solution, partially depleted in the volatile product, is itself collected in a specific circuit after cooling.. The solution is fed continuously into the evaporation chamber.. The solutions used are binary mixtures which are or are not ideal.. ...
Exergy analyses are essential tools for the performance evaluation of water desalination and other separation systems, including those featuring membrane distillation (MD). One of the challenges in the commercialization of MD technologies is its substantial heat demand, especially for large scale applications. Identifying such heat flows in the system plays a crucial role in pinpointing the heat loss and thermal integration potential by the help of exergy analysis. This study presents an exergetic evaluation of air-gap membrane distillation (AGMD) systems at a laboratory and pilot scale. A series of experiments were conducted to obtain thermodynamic data for the water streams included in the calculations. Exergy efficiency and destruction for two different types of flat-plate AGMD were analyzed for a range of feed and coolant temperatures. The bench scale AGMD system incorporating condensation plate with more favorable heat conductivity contributed to improved performance parameters including ...
An investigation has been made to develop a robust solar water purification system for remote areas without potable water or energy. Many stills have been studied, but few are practical due to low efficiency and water yield. A study of the global water supply and existing treatment methods has been made to understand the problem and to develop the design. Further analysis should lead to an apparatus that can supply potable water in remote, water or energy-deprived areas with minimal maintenance and long-term cost. Objectives for simple still design have been identified, as well as drawbacks in current designs. Employing active techniques such as spray evaporation, baffling, vacuum distillation, forced convection, separate chambers and membrane distillation are shown as areas of potential yield improvement.

The study aims at using of lignocellulosic residues of Cymbopogon martini to develop value added quality papers by eco-friendly pulping and bleaching techniques. C. martini grass is exclusively used to extract important geranium oil by distillation in crude direct fired stills. Anatomical, morphological and chemical studies indicate its similarities with hardwoods and its suitability for the production of chemical grade pulp. Molecular oxygen, which is specific oxidizing agent for lignin has an immediate drawback to its use, is the low solubility in cooking liquor. The diffusion problem of dissolved oxygen is reduced to insignificance because of looser and open structure in the lignocellulosic residues of C. martini after distillation. Distillation process makes the C. martini suitable for alkali-O2 delignification process by bridging over the problem of mass transfer of O2, which is far less than C. martini without distillation. C. martini produces 44.73% screened pulp yield at kappa number ...

The oldest, least expensive method for purifying water is through distillation. Like the earths hydrologic cycle, distillation works through the natural processes of evaporation and condensation.. As fluoride-concentrated water is heated, steam evaporates from the boiling water and condenses onto a surface. The condensation then collects into a new container, leaving the fluoride and other contaminants behind. The result is pure, distilled H20.. Like reverse osmosis, the process of distillation removes more than just fluoride but particles and ions altogether, leaving the water empty of minerals and slightly acidic. Remineralization is advised to raise the pH level and improve the quality of taste.. Home countertop distillation units can be purchased for convenient distilling whenever needed. Because of the relatively slow rate at which water is distilled, distillation units are more practical for individuals or small families. One drop cant fill an ocean, we all need to come together and ...
Steam distillation extraction kinetics regression models to predict essential oil yield, composition, and bioactivity of chamomile oil
Sustainability is what actually got me into the distillery industry. I was working on different projects surrounding aquaculture, agriculture, aquaponics, biomass energy, steam, pellet stove technology, which lead to water distillation, ethanol fuel distillation, and ultimately to our current endeavour, the distillery. The goal has always been to run a "green" business. Since we began operation of the distillery, I have been researching and experimenting with various ways to recycle the spent wash produced during the distillation process.. Historically, DSW (distillery spent wash) particularly from mollasses, has been difficult to recycle. It has a high BOD and COD, as well as a high pigment retention due to the dark color of the carmelized sugars in mollasses. Something important to remember is everything in the spent wash is non-toxic since it is just the remains of the sugarcane after processing and dead yeast cells. The BOD and COD can be alleviated through time spent in an aerobic reactor ...
