Influence of Petroleum-Refining Waste / Product Contaminated Soil on Properties of Porous Ceramic Article

Abstract

During the refining of crude oil, among other wastes, soil contaminated with oil products is produced. This is a viscous mixture of soil, various oil products and water. Every year more and more of this waste is accumulated, because there is no appropriate means for its utilization. The possibility for use the petroleum product contaminated soil in the production of ceramic articles was investigated. Thermographic investigations have shown that heating up to 140 °C causes a loss in specimen mass by 54 %, while the endothermic effect at 120 °C, is due to the evapourization of water. The material burns intensively at 300 – 460 °C temperature. The mass weight losses are correspondingly 15.7 and 7.4 %. The thermo-graphic investigation results show that waste burning occurs at higher temperatures, than for sawdust temperature. As a result, the CO emissions into the atmosphere are lower. The best results were achieved when this waste was added to the ceramic mass with sawdust at a ratio of 2:1.
