동해-삼척지역 석회석을 활용하여 습식배연탈황공정기술에 대한 적용성을 검토하기 위해 석회석의 물리화학적 특성이 탈황성능에 미치는 영향을 연구하였다. 실험은 ASTM 표준 시험방법인 염산적정법을 적용한 실험실 규모의 실험 장치를 이용하여 총중화능력을 측정하였다. 실험결과 총중화능력은 CaO 함량 등의 화학성분 보다 입자크기의 물리적 특성에 더 큰 영향이 있음을 알 수있었으며, 입자크기가 미립화 될수록 총중화능력의 값은 높아지는 것으로 확인되었다.
Abstract
It studies that effect of limestone of physicochemical characteristic on the performance of flue gas desulfurization (FGD) and application examination for technology of wet type FGD process and to utilize the limestone in Donghae-Samcheok. The experiment method was measured total neutralizing capability (TNC) using the lab scale experimental apparatus based on the HCl titration test. The results of TNC of limestone samples were more dependent on the physical characteristics including particle size rather than chemical compositions such as CaO content and particle size of limestone get smaller, TNC is increased.
