UDCC Computer Controlled Continuous Distillation Unit
The Computer Controlled Continuous Distillation Unit, "UDCC", 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 Computer Controlled Continuous Distillation Unit, "UDCC", is basically composed by a boiler on which different types of columns can be adapted (plate columns and Raschig rings column). An eight plate column, a reflux system, a tank for distillation, a vacuum pump and a feeding pump (for continuous feeding) 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 sensor. Distillation can be carried out at low pressures with the help of an adjustable vacuum pump. The pressure loss in the column can be measured with a pressure sensor.
It allows continuous operation and batch operation.
For proceeding to continuous feeding, a pump that can inject the substance directly into the boiler or in any of the plates is available.
The temperatures of the system are measured by sensors placed in strategic positions.
This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), and includes: The unit itself + a Control Interface Box + a Data Acquisition Board + Computer Control, Data Acquisition and Data Management Software Packages, for controlling the process and all parameters involved in the process.
