Technical Bulletin No. 0187: Reuse of Condensates from Kraft Recovery Plant Operations

  The attached Technical Bulletin notes that the kraft pulping industry had been moving steadily toward increased reuse of condensates from both black liquor evaporation and digester relief and blow heat recovery operations. In a number of cases it was found that reuse of condensates was dependent on first freeing them of odorous organic constituents. The study was therefore directed toward means for their removal through aeration stripping and chemical oxidation.
