Technical & economic evaluation of a mineral carbonation process using southern Québec mining wastes for CO2 sequestration of raw flue gas with by-product recovery

Abstract

This paper focuses on an energy and economic analysis of a mineral carbonation process developed to treat raw flue gas issued from an industrial plant. The process uses Serpentinite based mining residues available in very large quantities close to an industrial center in southern Quebec. A model based on a mass balance obtained from laboratory scale experiments allowed the evaluation of the energy requirements of the process. The integration of these results to the particular situation of the Québec province showed the process feasibility. In addition, economic investigations illustrated the profitability of such plant because of the high potential sale value of the carbonates produced. This..
