Abstract:
A direct-fired evaporator includes a closed vessel into which a slurry feed of a slurry is provided. The vessel includes an outlet for concentrated product and an outlet for solvent vapor. A furnace extends through the vessel under a level of the slurry. A burner is positioned at an entrance to an interior of the furnace. An agitator is disposed in the vessel so as to agitate the slurry around an outer wall of the furnace. Flue gases from combustion are used as a heat-transfer medium for evaporating the slurry. The direct-fired evaporator can be used as a first effect in a multi-effect evaporation system.
