Abstract

The present invention relates to an evaporation device with a housing 2, inside which a heat transfer surface unit 4 of a vapor compression evaporation plant and a heat transfer surface unit 3 on a multi-effect evaporation plant are arranged, both operating on the falling film principle. The black liquor, feed liquor or liquor from an earlier evaporation effect is fed via pipe 5 into the lower part of the evaporation device, wherefrom the liquor is. pumped by means of a pump 6 via pipe 7 into a distribution device 19 located above the heat transfer units. Liquor to be evaporated is discharged into a following evaporation effect via line 13. A heat transfer unit of the multi-effect evaporation plant receives vapor via pipe 8 from a preceding evaporation effect operating at a higher pressure. The heat transfer surface unit 4 receives a steam from compressor 9 via line 12.
