Our distillation units operate on the principle of evaporation and enable rapid and cost-effective integration into existing production and/ or purification systems.
The contaminated solvents or mixtures are heated and boiled using heat transfer media (themal oil, hot water, steam). The resulting vapors are reduced to a liquid state and cooled by a cooling unit.
Since thermal decomposition can happen when handling sensitive substances, our units operate on the gentle procedure of vacuum distillation. With this process the boiling point is significantly reduced as the process takes places on low pressure (vacuum). Thus, the decomposition is prevented and simultaneously the energy consumption and with this the operating cost are reduced.
Using vacuum the boiling point of the liquids to be separated is reduced as well as a possible foaming which can occur when water is present is clearly reduced. The components evaporate at a considerably lower temperature than under normal pressure.
The vacuum pump sucks the vapors through a condenser. Largely by the lack of confounding factors such as air or inert gas an ideal heat transfer is taking place, resulting in a very efficient recovery of the solvents or other substances.
Depending on the use case vacuum evaporators by DesbaTec can handle solvents having a boiling point up to 340°C (644F/ 613,15K) using individually designed vacuum systems.
The clean distllate can be recycled directly back into the production process or be collected in suitable containers.
Dissolved solids, also called residue, stay in the distillation vessel and are discharged after the process into suitable containers.
- Consistent quality of the solven (even after repeated distillation)
- Tailored systems depending on your requirements (e.g. processing rate of approx. 50 liters per day up to approx. 1.000 liters per hour)
- Flexible supply and removal of the solvents: from barrel-to-barrel distillation to hard piping or storage tanks very much is possible
- Minimization of fresh produce purchasing, storage and handling
- Significant disposal cost savings
