A chemical recovery process at the Permachem pulp mill in Lyons Falls, N. Y., employs a four-stage scrubbing system that uses waste heat from exhaust gases to conserve energy while removing particulate and sulfur dioxide from gaseous effluent. The recovered heat is used to concentrate process liquors in an evaporator. The system is more economical than using a supplemental boiler since a boiler would require fuel oil. Evaporating the liquor to 60 percent using an alternate source of energy would result in use of 300,000 gal of fuel oil per year, which would cost $75,000. In the recovery operation, spent cooking liquor from the pulping process is evaporated so that solids content is increased from nine to 60 percent. This material is then burned in a refractory-lined furnace. Heat from this combustion is used in the four-stage scrubbing unit before being discharged to the atmosphere. (MCW)
