Title: Sequestration of CO2 in Mixtures of Bauxite and Saline Waste Water

Abstract

Batch and semi-batch experiments were conducted to assess feasibility of utilizing mixtures of caustic bauxite residue slurry and produced brine from the Oriskany sandstone formation to sequester CO2 • Bauxite residue/brine mixture of 90/10 by volume sequestered 9.5 g of CO2 per liter of mixture (100 psig of CO2 at 20 ºC) • Carbon trapping is accomplished primarily through solubilization • Solution of the product mixture was neutralized following carbonation • Flow-through carbonation at 25 ºC and 1 atm. demonstrates that carbonation rates are acceptable for proposed process applications
