STRIPPING OF KRAFT PULPING PROCESS CONDENSATES: REGULATIONS, DESIGN AND OPERATION

• Basic regulations concerning the collection and stripping of foul pulping process condensates are included in this TIP.
• The strippers covered are those that remove Total Reduced Sulfur (TRS) and Methanol (MeOH) as required by the Cluster Rule.
• Fiber filters are a standard part of stripper system design , although their value is questionable. Many mills have operated for years with fiber filters bypassed.
• The potential for foaming is detected by measuring the conductivity of the foul condensate . A high conductivity indicates the presence of liquor, and the condensate can be dumped before it gets to the column.

It Provides information on:

• Safety precautions.
• Condensates for collection.
• Stripper system.
• Column operation.
• Control of contaminant removal.
• Stripper off gas (SOG) disposal.
