Abstract
The principal approaches to reducing the effects of global warming seek to slow the increase in atmospheric CO2 levels as a result of fossil fuel combustion for energy production and transportation. A process for hybrid carbon capture and mineralization are disclosed. The process utilizes both flue gas from (e.g., power plants) and reject brine from (e.g., desalination process). The process includes providing flue gas to react with an amine solution to produce carbamate; processing the carbamate in a reactor to regenerate amine and to produce a carbonate; treating reject brine to provide a ready-made brine for carbonation reaction; and processing the carbamate with salt from treating the brine to produce a carbonate.

A process for hybrid carbon capture and mineralization, the process comprising:
- providing flue gas to react with an amine solution to produce carbamate;
- processing the carbamate to regenerate amine and to produce carbonates;
- treating reject brine to provide ready-made brine for carbonation reaction;
- processing the carbamate with salt from treating reject brine to produce a carbonate;
- precipitation of a solid carbonate from a liquid phase;
- separating the solid carbonate from the amine solution;
- and
- washing the solid carbonate and drying the washed solid carbonate to produce the carbonate.
A process for hybrid carbon capture and mineralization, the process comprising:
- providing flue gas to react with an amine solution to produce carbamate;
- processing the carbamate to regenerate amine and to produce carbonates;
- treating reject brine to provide ready-made brine for carbonation reaction;
- and
- processing the carbamate with salt from treating reject brine to produce a carbonate,
- wherein the carbonate comprises an alkali metal of Group #1 (Li, Na, K, Rb, Cs, and Fr) and a carbonate ion, and
- wherein an entrainer is added.
