Ethanol was first produced thousands of years ago by fermentation of carbohydrates and in some countries large volumes are still produced by this method. Synthetic alcohol was first produced industrially in the s by indirect catalytic hydration of ethylene but suffered from disadvantages such as corrosion from the large volumes of sulphuric acid handled and the energy required for concentration. This route has been superseded by direct gas phase hydration of ethylene. The reaction is carried out at high temperature and pressure in a fixed bed reactor containing a phosphoric acid catalyst.

The molasses required for the process is sourced from sugar industries located in the vicinity. The installed capacity of the unit is 40 kilo litre per day KLPD which generates approximately m3 per day of effluent called spent wash.
The MPPL has installed thermophilic biomethanation reactor based on anaerobic methanation process for treatment of spent wash. By extracting and capturing methane enriched biogas in the anaerobic digester the project reduces CH4 emission that would have otherwise emitted from the existing open lagoon system in the absence of the project activity.
The project activity is anaerobic treatment of distillery effluent spent wash and collection of methane enriched biogas in a closed digester system. This reduces methane emissions into the atmosphere that would have otherwise been emitted from the existing open lagoons. And secondly, combustion of methane enriched biogas captured and other biomass in a boiler for generation of power through steam, thus converting its methane content into carbon dioxide thereby reducing its greenhouse gas effect.
Distillery is the allied of the sugar industry, as the bye-product of sugar factory molasses is the raw material for distillery. In view of the above, distilleries are the sugar factories to facilitate easy transportation of molasses which is an important factor in the cost of production. Meerut-Muzaffarnagar region is quite rich in sugarcane. Nearly a dozen sugar factories are functioning in the Districts of Meerut and Muzaffarnagar, considering all the points for the Bijnor in the year He also maintains the hygienic condition of fermentation house to control the pH of prefermentation, regular sterilization of wort line to control the specific gravity desired and inoculation and transfer timing.
To see proper temperature is maintained in all distillation plant. In this way each chemist is responsible for their work. Invertase converts sucrose to invert sugar and Zymase converts invert sugar into Ethyl Alcohol. Fermentation is a dynamic process involving a series of reactions. The cycle is known as Glycolysis. The lactic acid bacteria produce small amounts of a variety of products, some of which are volatile and contribute to the congeners in the distillate.
Molasses is transported in the cells via specific carrier proteins called Permeases where it is hydrolysed into 2 molecules of glucose. The Permeases are substrate and require metabolic energy for operation. Theoretically conversion of 1gm of glucose via fermentation yields 0. This theoretical value is never obtained due to carbohydrate utilization for cell maintenance, growth and formation of small amounts of glycerols and higher alcohols.
Fermentation efficiency also depends upon factors such as yeast strain and environmental parameters. An increase in temp. During a normal Fermentation heat is produced from active yeast growth and metabolism which causes a rise in temp. Then this temp rise can drastically affect yeast metabolism and ethanol. Increased heat tolerances are obtained with media containing oleic acid. The maximum concentration of ethanol that yeast can produce depends upon the yeast strain used.
Alcoholic fermentation of cane molasses is carried out by adopting anaerobic fermentation process in India. Generally two types of fermentation performed in distillery i. Fermentation are of following types. Continuous Fermentation 2. This process recently following in India, due to high technology it is not working properly.
Whole period of cellular activity of yeast can be divided into three stages: 1. Multiplication 2. Production of alcohol 3. Other products Better yield is obtained when fermentation is carried out at optimum activity of all types.
Number of cells is wash is kept constant. Consequently the speeds of changes become nil. Single stage Single stage continuous fermentation is that in which the entire operation is completed under the steady6 stage conditions in one vessel only where the nutrients at the same continuous rate. This Process simple one and specially adapted to the process involving only cell growth.
Double stage continuous fermentation Here instead of carrying out the fermentation in single fermentation, it is taken to another fermentation, which allows the secondary fermentation to complete.
Multistage continuous fermentation It employs a better way of vessels in series. Fresh medium being feed into first the effluent from it passes to the second and so on through as many successively increased resulting in their more effluent us in substrate and higher yield in product.
In this fermentation, the components phase column be handled separately. The first one day is for growth phase, second and success ending one may be for production of product and so on.
A tank of fermenter is filled with the prepared mash of raw materials to be fermented. The temperature and pH for microbial fermentation is properly adjusted, and occasionally nutritive supplements are added to the prepared mash.
The mash is steam sterilized in a pure culture process. Growth of microorganisms during batch fermentation confirms to the characteristic growth curve, with a lag phase followed by a logarithmic phase. This, in turn, is terminated by progressive decrements I in the rate of growth until the stationary phase is reached. This is because of limitation of one or more of the essential nutrients. In this process, number of vats was charged with fresh yeast in column from prefermenters in the ratio These fermenters are separately filled with diluted molasses of desired sp.
Cane molasses is an important by-product in the manufacture of cane sugar. Molasses is a thick, viscous dark brown in colour and easily miscible with water. It is obtained in process of manufacturing cane sugar, Molasses is used in fermentation industries for the production of Ethyl alcohol, Yeast production, acetone, Acetic Acid production and some other organic acid production, but the largest utilization of molasses in India at present is in the Alcohol Industry.
Brix 2. Sugar as T. Moisture 4. Non Nitrogenous organic acid 6. Wax 7. Colour dark brown 3. Total dissolved solids 4. Dissolved Oxygen Nil Quality of molasses Quality of molasses is generally depends upon the brix, total reducing sugars invert sugar percentage and ash percentage. Based on this parameter I. Above above Transportation of molasses is done under type control of Excise Inspector posted at Sugar Factory and Distillery.
The quantity of molasses for at least 3 month is needed for storage according to the capacity of distillery and the quantity of molasses. For a factory producing gallons of rectified spirit per day quantity of 50 tones of molasses is needed per day. The storage tank i.
Production of industrial alcohol is an age old practice. But with time, the usage areas as well as production techniques have gone through a major transformation. Industrial alcohol is distilled ethyl alcohol C2H5OH , normally of high proof, produced and sold for other than beverage purposes. It is usually distributed in the form of pure ethyl alcohol, completely denatured alcohol, especially denatured alcohol and proprietary solvent blends. Ethyl Alcohol is the common name for the hydroxyl derivative of the hydrocarbon ethane.

The chances are that you have used or consumed a product containing renewable ethanol in the past week. While most renewable ethanol produced in Europe needs up being used in your fuel tank, it is also used by many other industrial sectors to produce countless consumer products. Significant volumes of renewable ethanol are produced for the beverage and industrial markets from agricultural feedstock, such as grains and sugar beet. Perhaps the best-known end-user of renewable ethanol — after the transport sector — is the drinks industry. Renewable ethanol is used to make many kinds of spirits, such vodka, gin and anisette. The ethanol used as an intermediary product by the chemical, pharmaceutical or cosmetics industry is in many cases of the highest and purest possible quality. These are premium markets due to the additional steps in the alcohol production process that are necessary to achieve the required purity. The same high standards and processes apply when alcohol is used for the production of spirit drinks. For more information about the beverage and industrial uses of ethanol, please click here. What Is Renewable Ethanol?
Industrial biotechnology takes the biotech tools developed to fight disease and cure illness and applies them to the greatest challenges in industrial manufacturing, chemical synthesis, and renewable energy production. Industrial biotech companies use micro-organisms microbes and specialized proteins enzymes to develop new "biobased" products from renewable agricultural sources, and to make traditional manufacturing processes cleaner and greener. Industrial biotechnology is the key enabling technology for production of ethanol from all renewable feedstocks:. Recent advances in enzymes and fermentation microbes have improved the efficiency of corn ethanol production substantially:. New "no cook" enzymes have now been developed to extract the sugars in corn at room temperature, greatly reducing energy inputs and further improving the cost and environmental profile of ethanol from corn starch. Ethanol production from cellulosic biomass such as corn stalks, wheat straw, or switchgrass is now on the cusp of commercial production thanks to dramatic advances in the development of cellulase enzymes.
In 5 continuously operating distillation plants, on more than days out of the year we produce highly purified neutral alcohol from grain, sugar beets and sugar cane. We in large part developed the plants on our own and build them with competent partners from the region. This allows us to ensure that our standards for sustainable and highly-efficient production can be fulfilled.
This page looks at the manufacture of alcohols by the direct hydration of alkenes, concentrating mainly on the hydration of ethene to make ethanol. It then compares that method with making ethanol by fermentation. Ethanol is manufactured by reacting ethene with steam. The catalyst used is solid silicon dioxide coated with phosphoric V acid.
Некоторое время он фантазировал о том, кто же еще может жить там, внизу, под этой невинной с виду ряской, которая так и звала опуститься на нее и пробежаться по ее упругой поверхности. -- Я мог бы провести здесь время с немалой пользой,-- заявил ему Хилвар, который, судя по всему, был совершенно зачарован тем, что он только что. -- Надо думать, эволюция в этих вот условиях пришла к очень интересным результатам. Да и не только эволюция, но и обратный ей процесс деволюции -- это когда высшие формы жизни начали деградировать после того, как планета была покинута разумными обитателями.
Вопрос явно вызвал некоторое затруднение, и ответ был дан очень неохотно. - Естественно, мы консультировались с Центральным Компьютером.
