A pilot plant study of a process to recover the volatile constituents of the condensate derived from the evaporation of a sulfite spent wood pulping liquor has been made. The data from this one-year evaluation confirm prior work demonstrating that recovery of sulfur dioxide, furfural, methanol, and acetic acid (in the form of ethyl acetate) will yield reusable and salable materials, and provide 60 90% BOD reduction. The work reported covers four major sections: (1) Assay of condensate samples from supporting mills; (2) Operation and data of a pilot system comprising steam stripping, activated carbon adsorption, and fractional distillation; (3) Mass, heat, and BOD balances made according to the actual operating condition of the pilot plant at the Appleton Division mill of Consolidated Papers, Inc. to January 1973; and (4) Low temperature (200C) regeneration of carbon. Mass and heat balances, recoverable product values, and credits for BOD removal combine to show the process to be a favorable avenue for the elimination of the pollution potential of the sulfite condensate waste.
