Distillation of saline solution

Goal and requirements

The aim of the application was to distil only so much water that a pumpable saline solution remains in the flask. The saline solution should then be automatically removed from the evaporator flask.



The setup consisted of the Hei-VAP Industrial equipped with the glassware A1, in conjunction with the Automatic Module - Distimatic including residue extraction. Furthermore, the vacuum pump Rotavac 20 and the chiller Hei-CHILL 5000 were used.


Process and result

With the use of the Automatic Module Distimatic, a distillation rate of 4.5 liters / h was achieved at the first time. Thus, our system could meet the requirements and the result was positive. Further optimization of the process parameters will subsequently improve the distillation speed at the customer's site. A limiting factor is the rate of flow of saline solution into the flask. Due to the high salt content of the solution the flow rate is somewhat throttled compared to pure water.
