Batch Distillation Pilot Plant Technical Educational Equipment

DISa Batch Distillation Pilot Plant Technical Educational Equipment

The distillation column is completely made of glass and it consists of a reboiler, of a column with steel mesh packing and of a condenser with reflux valve and head.
Training program
This unit enables to deepen the following issues:
• Distillation of different mixtures (water / ethanol, water / methanol, methanol / propanol, etc…) versus the variation of the following operational parameters:
• reflux ratio
• reboiler heating power
• feeding composition
• residual pressure
• Mass balance
• Energy balance
• Flooding

• Calculation of the number of theoretical trays
• Automatic flow, pressure and temperature control by PID controller (for mod. DISa, only)
• Plant supervision by P.C. (for mod. DISa, only)
TECHNICAL SPECIFICATIONS:
Mod. DISa
Besides being provided with all the Technical specifications of mod. DIS, this model also includes the following additional items:
• Flowmeter of AISI 304 stainless steel for measuring the flow rate to the condenser, 4-20 mA output signal, range of 0 to 250 l/h
• Pneumatic control valve, DN 15 of AISI 316 stainless steel, Cv = 2.5
• Electropneumatic converter 4 to 20 mA/0.2 to 1 bar
• Electronic absolute pressure (in column) transmitter of AISI 316 stainless steel, range of 0 to 1000 mbar, 4-20 mA output signal
• 2 microprocessor multi-loop digital controllers, with 2 PID control loops (flow rate of water to the condenser and residual pressure, input and output signals of 4 to 20 mA
• Supervision software for Windows: it enables to control ON-OFF signals, analog signals coming from the PID controller, real-time trend and historical trend
