    Abstract: Disclosed is a method for solidifying carbon dioxide into carbonate, in which carbon dioxide is stably converted into and solidified into carbonate (mineral facies) by using steel slag or natural mineral by extracting an alkali component by supplying an ammonium salt solvent as an extraction solvent to raw slag and injecting carbon dioxide into an extract solution supplied to a carbonation reactor to produce carbonate precipitate from the extract solution through the induction of a conversion reaction of the carbon dioxide into the carbonate precipitate. Then after the above two step are performed at least one an acetic acid solvent is supplied as an extraction solvent to the raw slag so as to finally extract an alkali component; and carbon dioxide is injected into an extract solution to produce carbonate precipitate from the extract solution through the induction of a conversion reaction of the carbon dioxide into the carbonate precipitate.

    Abstract: Disclosed is a method for recovering carbon dioxide from exhaust gas, more particularly, a method for recovering carbon dioxide from exhaust gas for saving the cost for recovery of carbon dioxide by decreasing energy required for recycling a carbon dioxide absorbent solution. In particular, a circulating solvent, whose heat of vaporization and/or sensible heat is lower than that of a solvent of an absorbent solution introduced to a recycling tower, is supplied to the lower portion of the recycling tower and mixed with the heated absorbent solution. As a result, the pressure inside the recycling tower is maintained so that carbon dioxide released from the absorbent solution is discharged to a storage tank/drum.

    Abstract: A method of fixing carbon dioxide is provided. After metal ion components are extracted from natural mineral or steel slag through acid treatment, carbon dioxide is injected to fix carbon dioxide by carbonating the same. Since the procedure of pH adjustment is unnecessary, the reaction is carried out effectively, and a continuous process is enabled. Further, since the used extraction solvent is recycled, the cost of fixing carbon dioxide is reduced. The disclosed method of fixing carbon dioxide enables effective removal of carbon dioxide produced from the steelmaking industry, thereby significantly reducing greenhouse gas emission and allowing recycling of the conventionally discarded steel slag.
