An improved crude oil tank-cleaning process can reduce hazardous waste generated from tank bottoms and allow the recovery of valuable hydrocarbons. The process uses chemicals, heat, water, and applications technology. Crude oil tank bottoms are typically high in hydrocarbons -- a valuable raw material if recovered and recycled back to the refining process. Nalco's patented program essentially separates sludge into its components: water, nonhazardous solids, and recovered hydrocarbons. The paper describes industry trends, sludge removal, mechanical cleaning, chemical cleaning, environment and safety, case history of a New Jersey refinery, testing, program design, the cleaning process, hydrocarbon recovery, and return on investment.
