Abstract
Acidic hydrocarbon sludge from a petrochemical refinery operation was prepared for addition to landfills by stabilization. The sludge consisted of nonhazardous PAHs and aliphatic compounds and contained semivolatile and nonvolatile organics. Poor results were obtained using the conventional technique of solidification with portland or pozzolanic (lime/fly ash) cements. When the cementing process was preceded by clay microencapsulation, contaminants became immobilized and mechanical characteristics improved. As a result, leachate reductions and dimensional stability increases were demonstrated. Two clay types were used for the microencapsulation process: a clay containing a large amount of silt, which was found at the site, and spent fuller's earth with high attapulgite content. Good results for permeability and compressibility were found with both types of clay matrix.
