Abstract
- This paper is aimed at developing a systematic methodology for the cost-effective reduction of water usage and discharge in pulp and paper plants. As the industry moves towards increased system closure, the build-up of Non-Process Elements (NPEs) leads to serious consequences on the process equipment. In response, this paper achieves the following: • a mathematical model to track water and primary NPEs throughout the pulping process • rigorous targeting for water usage and discharge • a systematic framework for water reduction using mass integration strategies including no/low cost techniques as well as capital-based techniques • an optimisation model for the optimisation of allocation, recycle and separation of aqueous streams. A case study for water management in a kraft pulping process has been solved to highlight the usefulness of the devsied approach. [ABSTRACT FROM AUTHOR]
