Abstract
Technologies for the chemical recovery of nonwood black liquor are presented in this chapter. Nonwood plants contain a higher amount of silica than does wood. The maximum amount of silica gets dissolved during the pulping process and remains in the black liquor. The greater amount of silica in the black liquor from nonwood plants creates special operating problems during the chemical recovery process. Desilication of black liquor, and green liquor, soda recovery in the form of sodium hydroxide/sodium carbonate without heat recovery are discussed.
