Distillation Methods Wiped Film Distillation Advantages Wiped Film Distillation A rotating wiper system distributes the crude product to a film on the inner surface of a heated pipe. The wiping system speeds up the evaporation process by keeping the product film turbulent so that the heat transfer and mass transfer are optimised. The lower boiling fraction of the raw material evaporates out of the product film within a short time; the residence time of the product at the evaporator wall is very short. The vapours are condensed on an external condenser. The concentrate is continuously...

Horizontal Thin Film Evaporators Advantages Horizontal Thin Film Evaporators In order to increase the residence time of the product in the evaporator, the possible evaporation rate or the percent distillate, it makes sense to use horizontal evaporators, so that gravity has less influence on the product stream. In this type of evaporator it is possible to vary the required residence time within wide ranges. ∙ Continuous distillation process ∙ Very high evaporation rates and high distillate splits possible ∙ Suitable for reactive distillation Heating Media By increasing the product residence...

Laboratory and Pilot Tests at VTA Laboratory and pilot tests For complex mixtures, theoretical calculations are often not sufficient to design an industrial plant or to determine the optimum process conditions for a distillation. In the VTA test centre, tests for every offered technology can be performed. Analytics A central analytical department is assigned to the VTA test centre and tolling facilities. Retained samples of all raw materials and purified products are kept for at least three years. In this way VTA obtains a completely documented data base for the evaluation of products and...
