GHG Inventory for Opencast Coal Mining in India Based on Stoichiometric Combustion of Diesel and Simulation of Ethanol-Diesel Blend for Emission Reduction

Abstract

 Abstract —Use of HEMMs in mining is predominant key activity which results in increased CO 2 emission and thus contributing to the GHG due to diesel combustion in engine cylinder of HEMMs. This study involves the theoretical estimation of theoretical CO 2 emission based on the stoichiometric combustion of diesel consumed during the mining in India. Moreover, ethanol-diesel blending was simulated and reduction in theoretical CO 2 emission due to different blending fraction was estimated based on total fuel consumption by opencast coal mining industry in India. According to this study the increasing trend of diesel consumption and associated theoretical CO 2 emission was observed due to opencast mining as compared to present scenario in India. Average percentage reduction of theoretical CO 2 emission for simulated ethanol-diesel blending fraction E5, E10, E20, E25, E35 and E40 are 1.95, 3.95, 7.76, 9.79, 13.82 and 15.80 %
