McCabe–Thiele method. 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column that is being operated at total reflux (i.e., which means that no overhead product distillate is being withdrawn from the column).
Continuous distillation, a form of distillation, is an ongoing separation in which a mixture is continuously (without interruption) fed into the process and separated fractions are removed continuously as output streams. Distillation is the separation or partial separation of a liquid feed mixture into components or fractions by selective ...
Distillation. Laboratory model of a still. 1: The heat source to boil the mixture. 2: round-bottom flask containing the mixture to be boiled. 3: the head of the still. 4: mixture boiling-point thermometre. 5: the condenser of the still. 6: the cooling-water inlet of the condenser. 7: the cooling-water outlet of the condenser.
Distillation Design is a book which provides complete coverage of the design of industrial distillation columns for the petroleum refining, chemical and petrochemical plants, natural gas processing, pharmaceutical, food and alcohol distilling industries. It has been a classical chemical engineering textbook since it was first published in ...
Modeling and simulation of batch distillation unit. Aspen Plus, Aspen HYSYS, ChemCad and MATLAB, PRO are the commonly used process simulators for modeling, simulation and optimization of a distillation process in the chemical industries. [1] [2] Distillation is the technique of preferential separation of the more volatile components from the ...
In chemical engineering, azeotropic distillation usually refers to the specific technique of adding another component to generate a new, lower-boiling azeotrope that is heterogeneous (e.g. producing two, immiscible liquid phases), such as the example below with the addition of benzene to water and ethanol. Common Equipment used in Azeotropic ...
Such vapor–liquid equilibrium information is useful in designing columns for distillation, especially fractional distillation, which is a particular specialty of chemical engineers. [ 1 ] [ 2 ] [ 3 ] Distillation is a process used to separate or partially separate components in a mixture by boiling (vaporization) followed by condensation .
