2017

This paper is a presentation of the CO2stCap project to be undertaken in the four year project period (2015 – 2019). The project focuses on partial CO2 capture in process industry and how this can be applied to reduce cost. By performing techno–economic analyses, the optimal capture rate, including optimal design, application and configuration for different industry sources can be obtained. Cost estimation methods are used as a basis to identify and verify potentials for cost reduction when applying different options for implementation of partial CO2 capture. CO2stCap. Industries studied in this project are pulp & paper, steel, cement and metallurgical production of silicon for solar cells.

Reducing Carbon Footprint of Energy-Intensive Applications by CO 2 Capture Technologies: An Integrated Technical and Environmental Assessment

Chemical engineering transactions, 2019

Reducing the CO2 emissions from energy production sector as well as from other energy-intensive industrial applications (e.g. metallurgy, cement, chemistry etc.) is of great importance today. Carbon capture, utilization and storage (CCUS) technologies are under development to be implemented in fossil fuel-based industrial applications to reduce the carbon footprint. The main aim of this paper is to present, through illustrative coal-based examples, the CO2 capture technologies used to reduce the carbon footprint of energy-intensive processes. The assessments are focused on conceptual design, modelling and simulation, process integration and technical and environmental assessment of CO2 capture with potential applications in industrial sectors with high greenhouse gas emissions e.g. power generation, metallurgy, cement, chemicals.Two reactive gas-liquid and gas-solid carbon capture technologies are evaluated through illustrative industrial size examples. The CO2 capture rate is set t...
