Overview of Continuous Rectification

Continuous Rectification is included in the Interlabs Process Control Eengineering range. The product’s intended role, construction and suitability should be assessed using the manufacturer’s or supplier’s confirmed product information and the requirements of the task for which it is being considered.

Distillation is used to separate liquid mixtures made up of individual liquids that are soluble in one another. Rectification refers to distillation in a countercurrent.

Rectification refers to distillation in a countercurrent. Ethanol/water is recommended as the liquid mixture for the Continuous Rectification. It is fed into the column. It partially evaporates on its way to the bottom of the column where it is heated to boiling. The mixed vapour produced then moves upwards in the column. The mixed vapour contains a higher concentration of the component with the lower boiling point (ethanol). It leaves the top of the column and is condensed using a condenser and a phase separation tank. Part of this condensate is collected in a tank as product while the rest is fed back into the column. Here, on its way downwards, it undergoes further heating and material exchange with the rising mixed vapour. This exchange causes the vapour phase to become richer in ethanol and the liquid phase to become richer in water. The liquid phase moves to the bottom and can be collected in two tanks. A heat exchanger allows the feed to be preheated by the bottom product carried away from the column. A sieve tray column and a packed column are available. The sieve tray column has three connections at different heights for the feed. The packed column is filled with Raschig rings. The reflux ratio is adjusted using actuating valves. Relevant experimental parameters are recorded by sensors and displayed digitally and processed onto a PC. The software also allows adjustment of the evaporator and the reflux ratio using PID controllers.. It is fed into the column.
