Normal pressure operation
Distillation tower: stainless steel sieve tray, opening rate 5%
Total reflux: tray efficiency 30%-60%, single board efficiency 50%
Partial reflow: tray efficiency 40%-80%, single board efficiency 40%

The pipelines, valves and storage tanks of the experimental device are all made of stainless steel 304, which is beautiful in appearance, easy to operate, and has a safety alarm function.
Water: The device needs cooling water and has its own connection to the water pipe. Tap water enters the condenser at the top of the tower through the device interface and the rotor flow meter and is discharged.
Electricity: voltage AC220V, power 2KW, standard single-phase three-wire system. Each laboratory needs to be equipped with 1-2 ground points (safety ground and signal ground).
Experimental material: ethanol-n-propanol
