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.
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.
Design and operation of a distillation tower depends on the feed and desired products. Given a simple, binary component feed, analytical methods such as the McCabe–Thiele method [41] [50] or the Fenske equation [41] can be used. For a multi-component feed, simulation models are used both for design and operation.
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 ...
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.
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 ...
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 ...
Given a simple, binary component feed, analytical methods such as the McCabe–Thiele method [5] [6] [7] or the Fenske equation [5] can be used to assist in the design. For a multi-component feed, computerized simulation models are used both for design and subsequently in operation of the column as well.
