In some cases, the separation efficiency of a single stage wiped film distillation unit is not sufficient to achieve decent product qualities. In such cases wiped film evaporators (as reboiler) combined with a rectification column with several separation stages (theoretical plates) are used to increase the separation efficiency.
Advantages to use a wiped film evaporator as reboiler for the column:
The wiped film distillation systems with rectification column are set-up modular and consist in the basic configuration as follows:
The main components are fabricated in Borosilicate glass to enable observation of product properties like foaming, fouling and film distribution on the heated shell during distillation.
With laboratory units along with 3-4 kg of crude material, proper and reliable tests can be performed.
Further technical features
The systems are customized to the customers’ needs based on product properties and frequency of use. Besides the basic configuration the following options can be selected:
