AFT098 Continuous Rectification Trainer Educational Equipment Heat Transfer Lab Equipment
1 Description
Distillation is used to separate liquid mixtures made up of individual liquids that are soluble in one another. Rectification refers to distillation in a counterflow. Ethanol/water is recommended as the liquid mixture for it.
A sieve tray column, a bubble cap tray column and a packed column are available. The packed column is filled with Raschig rings. Each column has three connections at different heights for the feed. The top product 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. The reflux ratio is adjusted using valves. The bottom product can be collected in two tanks. A heat exchanger allows the feed to be preheated by the bottom product carried away from the column.
Relevant measured values are recorded by sensors. The composition of the feed and products is determined via an areometer based on the difference in density between ethanol and water.
The trainer is operated and controlled by the integrated PLC with touch screen. The measured values can be transmitted via LAN to a PC where they can be analysed using the software. By means of an integrated WLAN router, the trainer can additionally be operated and controlled via one end device and the user interface can be displayed on numerous end devices (screen mirroring). Menu navigation is independent of the user interface shown on the touch screen of the trainer. Different user levels with different functions are available on the end device. Data acquisition on end devices is possible via the network.
