Considerable attention has been given to carbon dioxide for its impact on climate change. Due to carbon dioxide being emitted from various chemical and petrochemical plants, the gases in geographically scattered places should be gathered, transported and sequestrated. The carbon dioxide disposal network resulting therefrom is a recently emerging issue that should be urgently addressed in the chemical industry in view of the continuously strengthened regulations. This paper proposes a mathematical modeling framework involving carbon capture and storage in order to obtain decision information such as how much captured CO2 to be held at which sites, and where to be sequestered. The applicability of the proposed framework is demonstrated with potential carbon dioxide networks in Korea, along with some remarks.
