Abstract
A partially-oxidized spent pulping liquor is produced which is added to unoxidized strong spent pulping liquor prior, during, or subsequent to concentration to form a novel partially-oxidized, concentrated, high total solids spent pulping liquor. This novel, partially-oxidized, concentrated spent liquor is capable of being combusted in a spent liquor recovery furnace without the addition of auxiliary heating fuel with a resultant increase in the effective capacity of that furnace.
