The McCabe–Thiele method is a technique that is commonly employed in the field of chemical engineering to model the separation of two substances by a distillation column. [ 1 ] [ 2 ] [ 3 ] It uses the fact that the composition at each theoretical tray is completely determined by the mole fraction of one of the two components.
Fractionation at total reflux. The Fenske equation in continuous fractional distillation is an equation used for calculating the minimum number of theoretical plates required for the separation of a binary feed stream by a fractionation column that is being operated at total reflux (i.e., which means that no overhead product distillate is being withdrawn from the column).
The other bulbs can be used to collect the distillates sequentially, when the desired fraction is being collected the bulb is cooled with water or ice to aid condensation. A motor drive is often used to rotate the string of bulbs to reduce bumping , give even heating, and increase the surface area for evaporation.
Warren Lee McCabe (August 7, 1899 – August 24, 1982) was an American Physical Chemist and is considered as one of the founding fathers of the profession of chemical engineering. [1] He is widely known for the eponymous McCabe–Thiele method for analysis of distillation processes and his book, Unit Operations of Chemical Engineering , a major ...
For instance, in a distillation of ethanol and water, water will boil out of the remaining ethanol, rather than the ethanol out of the water as at lower concentrations. Overall the pressure-swing distillation is a very robust and not so highly sophisticated method compared to multi component distillation or membrane processes, but the energy ...
After completing his doctoral thesis on steam-carbon reactions, he developed (jointly with McCabe) a graphical method of design for fractionating (i.e., distillation) columns as a transformational publication in Industrial and Engineering Chemistry in 1925. This approach to the design of distillation columns was rapidly adopted in undergraduate ...

Countercurrent distribution, therefore, is a method of using a series of vessels (separatory funnels) to separate compounds by a sequence of liquid-liquid extraction operations. Contrary to liquid-liquid extraction, in the CCD instruments the upper phase is decanted from the lower phase once the phases have settled.
