Pulp and paper Industry: Chemical Recovery examines the scientific and technical advances that have been made in chemical recovery, including the very latest developments. It looks at general aspects of the chemical recovery process and its significance, black liquor evaporation, black liquor combustion, white liquor preparation and lime reburning. It also describes the technologies for chemical recovery of nonwood black liquor, as well as direct alkali regeneration systems in small pulp mills. In addition, it includes a discussion of alternative chemical recovery processes, i.e. alternative causticisation and gasification processes and the progress being made in the recovery of filler, coating colour and pigments. Furthermore, it discusses the utilisation of new value streams (fuels and chemicals) from residuals and spent pulping liquor, and the environmental challenges.
