Continuous Distillation Pilot Plant vocational training equipment

DCa Continuous Distillation Pilot Plant vocational training equipment  

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 to the condenser: 4-20 mA output signal, range of 0 to 250 l/h
• Electronic absolute pressure transmitter (in column) of AISI 316 stainless steel , range of 0 to 1000 mbar, 4-20 mA output signal
• 2 microprocessor multi-loop digital controllers, with 3 PID control loops (flow rate of water to the condenser, residual pressure and pre-heating temperature)
• Supervision software for Windows: it enables to control ON-OFF signals, analog signals coming from the PID controller, real-time trend and historical trend
