BENEFITS OF THE FOUL CONDENSATE STRIPPER

In the Turpentine Recovery Area:

Cost Effective

• No prime steam required to drive this stripping system
• Inexpensive when compared to alternatives
• No extra labor or supervision required to operate this system
• Increases turpentine recovery
• Provides "clean" foul hot water for brown stock washing
• Cleans digester relief vapor of fiber and some liquid carry-over before the vapor reaches the turpentine recovery system
• Can be part of the original system or an easy retrofit/modification of existing system
• Fits easily into existing digester relief vapor line

   Reduces

• Cooling water supply requirements
• Condenser surface requirements
• Vapor load on existing condensing system
• BOD load to waste plant
• TRS emissions to the water and air

In the Multi-Stage Stripper Area:

In addition to many of the benefits above, the foul condensate stripper in the multi-stage area:

• Is a viable back-up for the typical multi-stage foul condensate stripping system whose primary unction is to remove methanol
• Cleans foul condensate feed thereby reducing (essentially eliminating) red oil formation in the stripping tower overhead
• Preheats multi-stage stripper feed
