鉄鋼スラグからの溶出物によるCO<sub>2</sub>海洋固定化能に関する研究 [in Japanese] CO<sub>2</sub> Sequestration Capacity using Chemical Extraction from Steel Slags in Ocean Space [in Japanese]
Access this Article
The concentration of the atmospheric CO<sub>2</sub> has been increasing since the middle of the 21<sup>st</sup> century. The iron and steel industries have produced extremely large amounts of slag as byproduct of the iron making and steel making processes. The purpose of this study is to estimate CO<sub>2</sub> sequestration capacity using chemical reaction from steel making slags. The chemical extraction of Ca and Mg from steel slag was investigated and the relationship between the gas transfer velocity and turbulent mixing at the water surface was also experimentally investigated. Based on these experimental results, we developed a numerical model for computing physical-chemical processes and for estimating CO<sub>2</sub> sequestration capacity in ocean space.
