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 9):
A wood pulping system comprising:\n a pulping unit for pulping wood or wood chips and which produces a liquor; a concentration unit for receiving the liquor from the pulping unit and concentrating the liquor to form a concentrated liquor and at least a foul condensate; a stripping column for receiving and stripping volatile compounds from the foul condensate; one or more mechanical vapor re-compression units for receiving a vapor and compressing the vapor to form steam wherein the steam is directed through the stripping column; one or more conduits for directing the foul condensate to the stripping column where the foul condensate moves through the stripping column and is contacted with steam that is moving through the stripping column to produce a clean condensate and a volatile rich vapor stream; a reflux condenser; a conduit for directing the volatile rich vapor stream from the stripping column to the reflux condenser; and wherein the reflux condenser receives the clean condensate and the volatile rich vapor stream and through a heat exchanger associated with the reflux condenser transfers heat from the volatile rich vapor stream to the clean condensate to partially evaporate the clean condensate and produce the vapor that is directed to the mechanical vapor re-compression units for forming steam.
