Process and device for separating a solid residue from its solution in stirred material bed

摘要

A process for separating solid residues from a soln. of vaporisable prod. and/or solvents, in the presence of up to 20 wt.% of high boiling hydrocarbons, the prod. being inert under vaporising conditions, comprises heating the mixt. to vaporisation temp., under vacuum, so that the prod. vaporises and is removed and condensed. The soln. is heated to vaporisation temp. in the presence of a fluidised bed of particles. Also claimed is the appts. for performing the process.
