  2. Steam distillation - Wikipedia

    en.wikipedia.org/wiki/Steam_distillation

    Steam distillation is a separation process that consists of distilling water together with other volatile and non-volatile components. The steam from the boiling water carries the vapor of the volatiles to a condenser ; both are cooled and return to the liquid or solid state, while the non-volatile residues remain behind in the boiling container.

    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.

    In 1943 the University of Chicago Press published a book titled Food Chemistry and Cookery by the then University of Chicago Associate Professor of Home Economics Evelyn G. Halliday and University of Minnesota Associate Professor of Home Economics Isabel T. Noble. In the foreword of the 346-page book, the authors state that, "The main purpose ...

  5. Distillation - Wikipedia

    en.wikipedia.org/wiki/Distillation

    Distillation, also classical distillation, is the process of separating the component substances of a liquid mixture of two or more chemically discrete substances; the separation process is realized by way of the selective boiling of the mixture and the condensation of the vapors in a still.

  6. Short-path distillation - Wikipedia

    en.wikipedia.org/wiki/Short-path_distillation

    Short-path distillation is a distillation technique that involves the distillate traveling a short distance, often only a few centimeters, and is normally done at reduced pressure. [ 1 ] [ 2 ] Short-path distillation systems often have a variety of names depending on the manufacturer of the system and what compounds are being distilled within them.

  8. Herbal distillate - Wikipedia

    en.wikipedia.org/wiki/Herbal_distillate

    The science of distillation is based on the fact that different substances evaporate at different temperatures. Unlike other extraction techniques based on solubility of a compound in either water or oil, distillation will separate components regardless of their solubility. The distillate will contain compounds that vaporize at or below the ...

  9. Vacuum distillation - Wikipedia

    en.wikipedia.org/wiki/Vacuum_distillation

    Vacuum distillation or distillation under reduced pressure is a type of distillation performed under reduced pressure, which allows the purification of compounds not readily distilled at ambient pressures or simply to save time or energy. This technique separates compounds based on differences in their boiling points.
