Units for solvent recycling (vacuum distillation)
Distillation principle
Our units work according to the distillation principle and afford a fast
and cost-efficient integration into existing production and/ or purification systems.
Dirty solvents or material mixtures are heated up by the employment of heat distribution media (Thermal oil, hot water, steam) bringing them to the boiling point where they then are allowed to simmer. Steams resulting from this are liquefied through condensation and then cooled in the radiator.
Thermal decomposition could be caused to sensitive material components during the evaporation process. In order to avoid this and reduce the power requirement at the same time, we use a careful more gentile distillation method.
The vacuum distillation method
Here the DesbaTec units are brought to a low pressure point, under the lower explosion limit by means of a vacuum pump. The vacuum pump sucks out the solvent steams through a condenser. This results in an almost inert gas free environment giving us an ideal heat transfer making a very efficient recuperation of the solvents or materials possible.
DesbaTec units can purify solvents with a boiling point of up to 290 °C (554 F/ 563,15 K) by insertion of individual designed vacuum systems.
The solved solids usually do not evaporate with this process, but remain in the distillation vessel and are then placed into specific containers planned for their removal.
