Abstract:
A system and process is disclosed for treating foul condensate such as foul condensate produced in a Kraft pulp mill. Foul condensate is directed through a steam stripper to produce a clean condensate that is partially evaporated by a volatile rich vapor stream produced by the steam stripper in the course of treating the foul condensate. Vapor produced by the evaporation of the clean condensate is directed to one or more electrically driven mechanical vapor re-compressors that produce the steam that is used in the steam stripper.

Claim (Index 1):
A wood pulping process and a method for treating foul condensate produced in the wood pulping process comprising:\n pulping wood and producing a liquor; concentrating the liquor in one or more evaporators to produce a concentrated liquor and at least a foul condensate; directing the foul condensate to a stripping column and directing the foul condensate downward through the stripping column; producing steam and directing the steam upwardly through the stripping column to strip volatile compounds from the foul condensate and producing a clean condensate and a volatile rich vapor stream that is vented from the stripping column; evaporating a portion of the clean condensate by heating the clean condensate with the volatile rich vapor stream and producing a vapor; and directing the vapor to one or more mechanical vapor recompression units and compressing the vapor to form at least a portion of the steam that is directed into the stripping column.
