DCa Continuous Distillation Pilot Plant Didactic Education Equipment for School Lab Chemical Engineering
The solution having to be distilled, stored in a glass tank, is sent to the distillation column by a metering pump after crossing a pre-heating exchanger. The column can be fed through 3 points at different height.
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:
- feed pre-heating temperature
- reflux ratio
- feeding flow rate
- 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. DCa, only)
- Plant supervision by P.C. (for mod. DCa, only)
TECHNICAL SPECIFICATIONS:
Mod. DCa
Besides being provided with all the technical specifications of mod. DC, this model also includes the following additional items:
- 2 pneumatic control valves of AISI 316 stainless steel,DN 15, Cv = 2.5
- 2 electropneumatic converters 4 to 20 mA/0.2 to 1 bar
- Flow meter of AISI 304 stainless steel for the flow rate tothe condenser: 4-20 mA output signal, range of 0 to 250 l/h
- Electronic absolute pressure transmitter (in column) ofAISI 316 stainless steel , range of 0 to 1000 mbar, 4-20 mAoutput signal
- 2 microprocessor multi-loop digital controllers, with 3 PIDcontrol loops (flow rate of water to the condenser, residualpressure and pre-heating temperature)
- Supervision software for Windows: it enables to controlON-OFF signals, analog signals coming from the PIDcontroller, real-time trend and historical trend
