Abstract
The bleached kraft pulp industry is a significant consumer of caustic soda, chlorine and sodium chlorate, the latter being reduced to chlorine dioxide at site.
The industry is now under considerable environmental pressure to reduce or eliminate its discharges of chlorinated organic compounds, including dioxins, which can be generated in the bleaching process.
This paper discusses the changes that are occurring in the industry in response to these pressures. It also analyzes the process options and the comparative process economics of these.
