  2. Ethanol fermentation - Wikipedia

    en.wikipedia.org/wiki/Ethanol_fermentation

    Ethanol fermentation, also called alcoholic fermentation, is a biological process which converts sugars such as glucose, fructose, and sucrose into cellular energy, producing ethanol and carbon dioxide as by-products.

  3. Distillation - Wikipedia

    en.wikipedia.org/wiki/Distillation

    Carbohydrate-containing plant materials are allowed to ferment, producing a dilute solution of ethanol in the process. Spirits such as whiskey and rum are prepared by distilling these dilute solutions of ethanol. Components other than ethanol, including water, esters, and other alcohols, are collected in the condensate, which account for the ...

  4. Ethanol - Wikipedia

    en.wikipedia.org/wiki/Ethanol

    Ethanol (also called ethyl alcohol, grain alcohol, drinking alcohol, or simply alcohol) is an organic compound with the chemical formula CH 3 CH 2 OH. It is an alcohol , with its formula also written as C 2 H 5 OH , C 2 H 6 O or EtOH, where Et stands for ethyl .

  5. McCabe–Thiele method - Wikipedia

    en.wikipedia.org/wiki/McCabe–Thiele_method

    A McCabe–Thiele diagram for the distillation of a binary (two-component) feed is constructed using the vapor-liquid equilibrium (VLE) data—which is how vapor is concentrated when in contact with its liquid form—for the component with the lower boiling point. Figure 1: Typical McCabe–Thiele diagram for distillation of a binary feed

  6. List of purification methods in chemistry - Wikipedia

    en.wikipedia.org/wiki/List_of_purification...

    Distillation, widely used in petroleum refining and in purification of ethanol separates volatile liquids on the basis of their relative volatilities. There are several type of distillation: simple distillation, steam distillation etc. Water purification combines a number of methods to produce potable or drinking water.

  7. Fractional distillation - Wikipedia

    en.wikipedia.org/wiki/Fractional_distillation

    In this example, a mixture of 96% ethanol and 4% water boils at 78.2 °C (172.8 °F); the mixture is more volatile than pure ethanol. For this reason, ethanol cannot be completely purified by direct fractional distillation of ethanol–water mixtures. The apparatus is assembled as in the diagram.

    The BatchFrac is rigorous model used for simulation of batch distillation column present in the model library of the software. It also includes the reactions occurred in any stage of 'Figure 2 –process flow diagram of batch distillation column (for ethanol and water)' the separator.

  9. Still - Wikipedia

    en.wikipedia.org/wiki/Still

    The simplest standard distillation apparatus is commonly known as a pot still, consisting of a single heated chamber and a vessel to collect purified alcohol. A pot still incorporates only one condensation , whereas other types of distillation equipment have multiple stages which result in higher purification of the more volatile component ...
