IM231211S51 Double-effect Falling-Film Evaporation Pilot Plant

[2] Consists of two falling-film shell-and-tube evaporators and of a shell-and-tube condenser.
[3] Metering pump for feeding the evaporator and it works under vacuum thanks to a liquid-ring vacuum pump.
[4] Two PID controllers that enable to control the flow rate of steam reaching the evaporator, the vacuum degree in the system and the level of the first stage, automatically.
[5] Two graduated tanks of borosilicate glass for measuring the condensate
[6] Calibrated diaphragm of stainless steel with differential pressure transmitter stainless steel for measuring the steam flow rate
[7] Pneumatic valve of stainless steel for the control of steam flow rate and working pressure
[8] Liquid-ring vacuum pump provided with air/water separator and solenoid valve for feeding water
[9] Supervision software for Windows: it enables to control ON-OFF signals, analog signals coming from PID controller, real-time trend and historical trend
