• Integrated pulp and paper mill

In this study a mechanical pulp and paper mill is analysed using advanced composite curves. It is a graphical pinch-based approach that takes into account the existing heat exchanger network and the utilities actually used at the mill. The possibilities of making a cost-effective heat exchanger retrofit in an operating mechanical pulp and paper mill are discussed. The study also shows that the advanced composite curves can be used to describe the amount of nonisothermal mixing taking place in the process.
