Abstract
A neutralization/sequestration process is provided for concomitantly addressing capture and sequestration of both COand SOfrom industrial gas byproduct streams. The invented process concomitantly treats and minimizes bauxite residues from aluminum production processes and brine wastewater from oil/gas production processes. The benefits of this integrated approach to coincidental treatment of multiple industrial waste byproduct streams include neutralization of caustic byproduct such as bauxite residue, thereby decreasing the risk associated with the long-term storage and potential environmental of storing caustic materials, decreasing or obviating the need for costly treatment of byproduct brines, thereby eliminating the need to purchase CaO or similar scrubber reagents typically required for SOtreatment of such gasses, and directly using COfrom flue gas to neutralize bauxite residue/brine mixtures, without the need for costly separation of COfrom the industrial byproduct gas stream by processes such as liquid amine-based scrubbers.
