CO2 mineralisation: Concept for co-utilization of oil shale energetics waste streams in CaCO3 production

摘要

An insight into an innovative approach for CO2 capture and beneficiation of alkaline waste streams originating from oil shale based power production in the form of a precipitated calcium carbonate (PCC)-type material is given. The main results of the study are highlighted including mathematical aspects and product characteristics. A technological concept for continuous mode co-utilization of waste streams is introduced and a pilot-scale reactor system is proposed. Also, several technological recommendations are given to come to an optimal process design.
