methanol for incineration. A few mills are "hard-piped'' to send this methanol-laden stream to bio-treatment ponds, thus avoiding incineration. It was estimated that, by the end of 2001, about 70% of the Kraft pulp mills in the United States would have stripping units for this purpose. Stripper overhead gas (SOG) comprises more than methanol.
