Fremgangsmåte og innretning for opparbeiding av stoffblandinger med minst to faser med forskjellige koketemperaturer

摘要

Two phase mixtures of materials with different boiling points are separated and at least 1 component is recovered in a process that treats the mixture at a pressure < 50 mbar and a temperature at which only the phase with the lower boiling temperature is vaporised. The vapour is condensed (K1) and the condensate collected in a receiver (B1) that can be shut off. As the temperature gradient varies as a result of the release of this phase, the receiver (B1) is shut off from the 1st condenser (K1). The remaining mixture is processed at an increased temperature and at least 1 of the phases with the higher boiling point is expelled and the vapour condensed. Also claimed is an apparatus for carrying out this process.
