This study proposed simultaneous disposal and utilization process of desalinated reject brine and CO2, or brine-based carbon capture and utilization (CCU). Using metal cations in desalinated reject brine, the feasibility of amines with different structural properties as crystallization inhibitors, morphol. controller of calcium carbonate formation was investigated in this study. Ca2+ ions were separated from desalinated reject brine in a salt refining plant by using a pH swing method and used for CaCO3 formation. Through this process, disposal of the large amount of metal cations in the desalinated reject brine was achieved. CO2 was selectively captured by alkanolamine, alkylamine, and multi-amine CO2 carriers with numerous amino groups and carried into the separated Ca(OH)2 to generate CaCO3. X-ray diffraction (XRD), SEM (SEM), and Fourier-transform IR spectroscopy (FT-IR) were used to investigate crystal shape and polymorph of the product. Addnl., thermogravimetric/derivative thermogravimetric anal. (TG/DTG) was used for purity anal. The results demonstrated that crystallization inhibition depending on structural properties of amines was possible, leading to successful CaCO3 polymorph control. The results of this research can be applied to process where the industrial production of metal carbonates based on inorganic CCU and disposal of the desalinated reject brine were involved. In the part of experimental materials, we found many familiar compounds, such as 3-Aminopropan-1-ol(cas: 156-87-6Reference of 3-Aminopropan-1-ol)
3-Aminopropan-1-ol(cas: 156-87-6) belongs to anime. To avoid the problem of multiple alkylation, methods have been devised for “blocking” substitution so that only one alkyl group is introduced. The Gabriel synthesis is one such method; it utilizes phthalimide, C6H4(CO)2NH, whose one acidic hydrogen atom has been removed upon the addition of a base such as KOH to form a salt.Reference of 3-Aminopropan-1-ol
