Abstract
A process is described for preventing plugging of distillation equipment when the distillable liquid comprises a mixture of different liquids containing a dissolved substance tending to precipitate from the distillate. An adjuvant is provided to the mixture to be distilled, which adjuvant forms a composition with the dissolved substance that, if isolated, melts at a lower temperature than the distillation temperature.
Claims8
In the distillation in a column of a distillable liquid component from a liquid mixture containing a higher boiling liquid component and a dissolved solid having a melting temperature higher than the distillation temperature used to distill said distillable liquid component from said liquid mixture, the improvement which comprises adding to said liquid mixture a normally solid adjuvant which forms with said dissolved solid a solute mixture that, if isolated, melts at a lower temperature than said distillation temperature.
