Abstract
The present invention concerns a process for the thin layer evaporation of liquid in which the thin layer to be evaporated is formed by centrifugation. It is characterized in that the pointed part of the said cone is immersed in a reserve of liquid to be evaporated and a communication is established between the external face of the said pointed part of the cone and the internal face of this cone, so that the thin layer subjected to evaporation is formed on the internal face and on the external face of the cone. It concerns a device and installation for the distillation by evaporation in thin layers, particularly for hydrocarbons, and process for operating this device.
