Abstract

The lime industry accounts for about 75% of greenhouse gases generated from process emissions, and because large amounts of fossil fuels are used, the intensity of greenhouse gas emissions per unit of product production is quite high. In order to respond more accurately and quickly to greenhouse gas regulations, including the domestic emissions trading system, it is necessary to establish a system for accurately identifying greenhouse gas emission sources and calculating emissions for each lime manufacturing process. In this study, in order for limestone processing companies to effectively respond to the domestic greenhouse gas emissions trading system, the operation method, input raw materials, and fuel differences for each type of limestone kiln were identified through field surveys, and the greenhouse gas emission intensity was analyzed As a results, it was confirmed that greenhouse gas emissions were reduced when using a Parallel flow regenerative kiln compared to an improved shaft kiln even when the same amount of limestone was used.

석회 산업에서 발생하는 총 온실가스 중 약 75%가 공정배출에서 발생하며, 이는 소성공정에서 석회석의 탈탄산 반응에 의해 배출되는 비율이다. 또 석회석 소성 공정에서 다량의 화석연료를 사용하므로 소성공정에서의 온실가스 배출 원단위는 매우 높다. 향후 국내 배출권거래제를 포함한 온실가스 규제에 보다 정확하고 신속하게 대응하기 위해서는 석회 제조 공정별로 정확한 온실가스 배출원 규명 및 배출량 산정을 위한 체계를 정립할 필요가 있다. 이에 본 연구에서는 석회석 가공 업체들이 국내 온실가스 배출권거래제에 효과적으로 대응하기 위해 석회석 소성로 유형별 운전 방식, 투입원료 및 연료 차이 등을 현장 조사를 통해 파악하고 온실가스 배출량 원단위를 분석하였다. 분석결과, 유체로를 사용하는 경우 토중로 대비 효율이 향상되어 같은 양의 석회석을 사용하더라도 온실가스 배출량이 감소하는 효과를 확인하였다.
