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.
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.
The design and operation of a fractionating column depends on the composition of the feed as well as the composition of the desired products. Given a simple, binary component feed, analytical methods such as the McCabe–Thiele method [5] [8] [9] or the Fenske equation [5] can be used. For a multi-component feed, simulation models are used both ...
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 ...
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 ...
"Short path" refers to the short distance that the vapors of the distillate need to travel, which helps reduce loss and speed up collection of the distillate.This type of distillation is generally performed under vacuum to prevent the compound from charring due to atmospheric oxygen, as well as to allow the distillation to proceed at a lower temperature.
Former FBI Deputy Director Andrew McCabe on Monday called for a “rethinking” of the methods used to protect former President Trump, in light of a second apparent assassination attempt this ...
Molecular distillation is a type of short-path vacuum distillation, characterized by an extremely low vacuum pressure, 0.01 torr or below, which is performed using a molecular still. [1]
