ABSTRACT
The petroleum refining industry is required to operate under increasingly stringent environmental regulations. In the past decade, refineries have had to conform to new environmental regulations dealing with effluent quality, solids disposal, vapor emissions, hazardous materials containment, and remediation of contaminated areas. Addressing these requirements invariably generates an increased quantity of solids requiring disposal. In many cases these solids fall under the “hazardous waste” definition. Disposing of these hazardous wastes is becoming a critical issue for the refining industry.
