Process for recovering crystals from a slurry |
摘要 |
<p>A process for recovering crystals from a slurry which comprises supplying a slurry comprising crystals and a solvent to a rotary vacuum filter and successively conducting filtration under suction, washing, filtration under suction and cleavage of a cake continuously by rotation of a cylindrical filter medium, wherein a vapor having a same composition as that of the solvent is supplied as a blowing gas for cleaving the cake. The crystals can be continuously recovered for a long period of time without clogging of a filter medium when the crystals are recovered from a slurry by using a rotary vacuum filter. <IMAGE></p> |
