Gasification of black liquor with subsequent production of for example electricity or biofuels is one of several biorefinery concepts linked to the chemical pulp and paper industry which is currently under development. The project aims, through a system analysis to compare black liquor gasification with other, both new and more proven, biorefinery concepts from economic and climatic point of views. First, mass and energy balances for the integration of different concepts are calculated, and then the effects on the surrounding energy system are investigated. The study will include different types of mills, with different steam balances, for which the applicability and performance of various biorefinery concepts will vary.
