Abstract

This study analyzed the amount of carbon dioxide reduction and economic benefits of detailed processes of CO₂ 6,000 tons plant facilities with mineral carbonation technology using carbon dioxide and coal materials emitted from domestic circulating fluidized bed combustion power plants. Coal ash reacted with carbon dioxide through carbon mineralization facilities is produced as a complex carbonate and used as a construction material, accompanied by a greenhouse gas reduction. In addition, it is possible to generate profits from the sales of complex carbonates and carbon credits produced in the process. The actual carbon dioxide reduction per ton of complex carbonate production was calculated as 45.8 kgCO₂eq, and the annual carbon dioxide reduction was calculated as 805.3 tonCO₂, and the benefit-cost ratio (B/C Ratio) is 1.04, the internal rate return (IRR) is 10.65 % and the net present value (NPV) is KRW 24,713,465 won, which is considered economical. Carbon mineralization technology is one of the best solutions to reduce carbon dioxide considering future carbon dioxide reduction and economic potential.

탄소광물화 기술은 석탄재와 이산화탄소를 반응시켜 건설재료 등으로 활용이 가능한 복합탄산염 등의 부산물을 생산함과 동시에 이산화탄소를 탄산염에 고정화하여 온실가스 감축효과를 얻을 수 있는 기술로, 이산화탄소 감축 및 경제적 잠재력을 고려하면 국가 온실가스 감축 목표를 실현하기 위한 유용한 방안이 될 수 있다. 그러나 아직까지는 해당 기술의 이산화탄소 감축 성능과 환경적인 이점, 경제성 등에 대한 자료가 적어서 기술의 상용화 가능성에 대해서는 명확하지 않은 상태이다. 본 연구는 국내 순환유동층 발전소에서 발생되는 이산화탄소와 석탄재를 이용하는 이산화탄소 투입량 기준 6,000 tonCO₂/년 규모의 탄소광물화 설비에 대해 이산화탄소 감축량 및 경제성 분석을 수행했다. 공정 분석 결과 1톤의 복합탄산염 생산 시 실질적인 이산화탄소 감축량은 약 45.8 kgCO₂eq, 연간 약 805.3 tonCO₂로 산정되었으며, 경제적 편익 분석 시 비용편익분석비(B/C Ratio)는 1.04, 내부수익률(IRR)은 10.65 %, 순현재가치(NPV)는 24,713,465 원으로 나타나, 탄소광물화 설비가 어느 정도 경제성을 확보하고 있는 것으로 분석되었다.
