UDDB バッチ式蒸留装置



The Batch Distillation Unit, "UDDB", designed by EDIBON, is a powerful laboratory tool for the study of variables affecting the distillation process. The student can investigate the principles that govern the transfer of matter and energy, as well as determine the optimum operating point for carrying out a large number of separations.



The Batch Distillation Unit, "UDDB", is basically composed by a boiler on which different types of interchangeable columns can be adapted (plate columns and Raschig Rings column). An eight plate column, a reflux system and a tank for the distillation are included.

The steam that goes to the head of the column is sent to a total condenser. The cooling water flow that crosses the condenser is regulated and indicated in a flow meter.

The pressure loss in the column can be measured with a manometer.

The temperatures of the system are measured by temperature sensors placed in strategic positions.
