    摘要： Apparatus for the crystallization and recovery of sulfur including a crystallizer vessel with inlet means for introducing a solvent with sulfur dissolved therein into the vessel at one level, and means for injecting an immiscible heat-exchange liquid at a different temperature from that of the solvent into the vessel at at least one other level different from the first level. The apparatus includes individual means for withdrawing heat-exchange liquid from the vessel, means for withdrawing crystalline sulfur slurry therefrom, and means for separating sulfur from this slurry.
