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.

• Thorough and in depth coverage of scientific and technical advances in chemical recovery in pulp making.
• Discusses alternative chemical recovery processes, i.e. alternative causticisation and gasification processes.
• Progress being made in the recovery of filler, coating colour and pigments.
• Utilisation of new value streams (fuels and chemicals) from residuals and spent pulping liquor
• Discusses Environmental challenges (Air Emissions, Mill closure)
• Presents ways in which the economics, energy efficiency, and environmental protection associated with the recovery process can be improved
