Download or read book Pulp Bleaching Today written by Hans Ulrich Suess and published by Walter de Gruyter. This book was released on 2010 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the most effective application of chemicals in bleaching. It starts with a brief overview of the history of bleaching and then focuses on recent developments. The ban of chlorine from bleaching pulp has shifted bleaching to environmentally sound procedures. Elementary Chlorine Free bleaching (ECF bleaching) and Totally Chlorine Free bleaching (TCF bleaching) are explained. The potential of different bleaching chemicals is exemplified in detail with a special focus on what to do and what to avoid. Very recent knowledge about the sources of yellowing is utilized to explain the ideal strategy for the removal of chromophores and their precursors. Emphasis is placed on applicable bleaching, in clear contrast to sophisticated, complicated or simply expensive pseudo modern bleaching. The target of this book is to explain the potential and the limitations of different chemicals and to demonstrate the necessity of comprehensive solutions for an environmentally sound use of the raw material wood, of chemicals, and of water in the production of pulp with top quality and yield. This book should educate students in the art of bleaching, assist mill personal in their continuous effort for process optimization, help research and technology managers to successfully select their targets, and be on hand as reference of the most recent bleaching technology.

Book excerpt: Report analyzing the status of chemical pulp bleaching technology in Canada in 1993, including overall chemical and energy usage and related emissions; new and emerging technologies for the reduction or elimination of elemental chlorine and chlorine containing compounds in chemical pulp bleaching; the anticipated status of technology in 1997 and 2002 based on the expectation that the current best economically achievable technology will be in widespread use at that time; the anticipated state of technology in 2010 based on an extrapolation of current trends in emerging technology; and specific areas of research and development required to bring technologies to implementation. The report also outlines the current practices and trends for pulp bleaching in Europe and environmental regulations for absorbable organic halides (AOX) discharges in pulp mill effluent that may be implemented in Canada, the United States, and Europe over the next 10 years. Bleaching data, taken from file data, specific information received from individual mills, trade directories, and regulatory agencies, was compiled for the 43 bleached chemical pulp lines in operation at the end of 1993.
