Recognition, classification and waste management of shiraz oil Refinery based on RCRA method

AbstractThe management of Industrial solid wastes such as oil sludge and un industrial wastes is one of themost appropriate methods for reducing the adverse effects of industrial activities on the environment.The purpose of this study is identifying and classification of wastes in order to manage them until thelast stage of waste management in shiraz oil refinery. The field study has been accomplished in Shirazoil refinery. Based on the research, after studying production process, the points of waste production,and the period of waste discharge, the type and tonnage of waste production were recognized. Thenspecific codes allocated to the recognized wastes by RCRA and separated to dangerous and nondangerouswastes. After recognizing the productive residues specified by rule's RCRA the resultsshowed that 43% of productive industrial wastes in Shiraz oil refinery are dangerous. Of totaldangerous wastes recognized, 91% were in the list of F (lists of dangerous wastes with unknownsource) and of 9% in K list (lists of dangerous wastes with specified source) so that, 54 % of wastemass have toxic properties, 22% of flammability, 23% reactive and 1% were corrosive. Finally, thecorrect way of productive residues in Shiraz oil refinery should be based on the hierarchical presentedof Environmental Protection Agency of America, and it was offered to use the new methods forreducing the production of oil sludge and suggested a place with the appropriate specifications in orderto Maintain the special industrial waste.
