DCa Continuous Distillation Pilot Plant Didactic Education Equipment for School Lab Chemical Engineering

Description

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
