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.
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.
A theoretical plate in many separation processes is a hypothetical zone or stage in which two phases, such as the liquid and vapor phases of a substance, establish an equilibrium with each other. Such equilibrium stages may also be referred to as an equilibrium stage, ideal stage, or a theoretical tray. The performance of many separation ...
Batch distillation. Batch distillation[1] refers to the use of distillation in batches, meaning that a mixture is distilled to separate it into its component fractions before the distillation still is again charged with more mixture and the process is repeated. This is in contrast with continuous distillation where the feedstock is added and ...
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] It is a process of separation, purification and concentration of natural products, complex and thermally sensitive molecules for example vitamins and ...
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.
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 ...
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 ...
