Tiivistelmä
Pulp and paper industry globally accounts around 6% of total CO2 emissions worldwide. There is a new path for implementing carbon capture technologies not only power sector, but also to industrial sector due to changes in global energy policies, which are set to decrease greenhouse gas emissions. Carbon emissions from pulp and paper industry are treated as carbon neutral due to their biological origin, which transforms the conventional carbon capture technologies to biomass-based carbon capture technologies.
The objective of this Master’s Thesis is to integrate carbon capture, storage and utilization to a pulp mill. Amine-based carbon capture technology was taken as a base for the integration due to its applicability and commercial availability. There are several possible ways of carbon capture integration: after carbon capture there exists the option to store it, utilize it, or use both at the same time. The aim of the thesis was to evaluate these possibilities from technological and economical point of view.
The key results show that excess electricity and heat from the pulp mill allow the integration of bioenergy carbon capture and storage (BECCS) or bioenergy carbon capture, utilization and storage (BECCUS). Furthermore, with lower electricity and heat market prices, and higher carbon and green methanol prices, the scenarios with integrated BECCS and BECCUS become realistic and feasible.
