Abstract

A new sequestration process of anthropogenic CO ₂ using waste cement was proposed. The proposed process contains two main reactions. The first reaction is an extraction reaction of calcium ion (Ca ²⁺) from waste cement particles by pressurized CO ₂. The second reaction is a precipitation reaction of CaCO ₃. Ca ²⁺ extracted from waste cement was deposited as a CaCO ₃ when the pressure was reduced to the low CO ₂ pressure. CaCO ₃ was directly disposed or recycled as a raw material of cement production. Energy consumption for the operation was 25.9 Mw/100-Mw power generation, and the sequestration cost was ∼ $83/1 ton carbon sequestration.
