| 摘要 |
The invention relates to a device for recovering solvents from a hydrocarbon mixture contaminated with impurities, comprising a container (12) with a jacket (12'), to which is assigned a heating device (18) for evaporating the solvent, a head (12'') covering the jacket (12') to which is assigned a cooling device (20) for condensing the evaporated solvent, and an inlet (22) for introducing the contaminated hydrocarbon mixture into the container (12). The head (12'') of the container (12) on its inner side has a surface (28) for condensing the solvent which runs upwards and is substantially shaped like a cone or has a similar shape, and, adjoining and situated below said surface (28), a collecting channel (30) for drawing off the condensed solvent. The invention also relates to a corresponding method. |
