Reduction of Hydrocarbon Emissions Can Be Costly

摘要

The purpose of this paper is to share the Lone Star Greencastle Indiana Plant's, experiences with changing raw materials in the klin feed to reduce hydrocarbons emissions. The original change of the plant's kiln feed composition was made in July of 1995. The plant changed the kiln feed composition for the first time since the plant opened. Shale was replaced in the kiln feed composition with clay, mill scale, and foundry sand, solely to reduce hydrocarbon emissions. At the time it was something that had to be done to keep burning liquid waste, inon order to comply with the BIF Tier II limit of 20 ppm of hydrocarbon emissions. The change of raw materials did accomplish what it was supposed to by reducing the hydrocarbon emissions under the allowable limit. Plant presonnel did not want to change raw materials, but did not have much of a choice, and had no idea of the repercussions that would follow. I will disscuss the positive and negatives of the different raw mix compositions.
