Energy system consequences when installing an advanced delignification process

Journal article, 2006

In the pulp and paper industry, during major modernization projects the overall energy system consequences are often not estimated in detail, usually only local energy consequences are taken into account when evaluating possible projects. In this paper, the effects on the overall energy system when installing an advanced delignification process (i.e., a "state-of-the- art" pulp digester and oxygen delignification process) will be presented. Also, the effect such an installation has on the potential for further energy integration is discussed. Furthermore, the CO2 consequences for both installing such a system and integrating the mill further energy-wise are presented.
