The future carbon dioxide free Kraft pulp mill - Technoeconomic and environmental assessment

Short Introductive summary

While the Swedish pulping industry steadily has decreased its greenhouse gas emissions over the last decades, the decline has lately stalled. This means that for the pulping industry to keep reducing their greenhouse gas emissions to reach carbon neutrality, more measures need to be taken. However, the energy- and chemical recovery of a Kraft pulp mill is a complex and interlinked system. This makes it challenging to beforehand predict changes in material- and energy flows when changes are implemented. Consequently, this can lead to unintended negative effects from an environmental life cycle perspective in cases when changes were made to improve the environmental performance of the mill. A solution to this is the creation of a digital model of the plant, i.e. a so called “digital twin”. This enables the simulation of the effects of systems changes when altering production parameters in the digital model, and thereby helping to avoid erroneous process alterations in the real plant In this study, we define and model the future Kraft pulp mill with the aim of achieving carbon neutrality by adding novel technologies such as carbon capture and storage. To achieve this, a digital twin
