Refinery slop oil sludges are classified by Resource Conservation and Recovery Act (RCRA) regulations as a hazardous waste. Typical means of disposal include landfilling, landfarming and incineration. As these alternatives become more costly, volume reduction is imperative. Recently, some U.S. refineries have moved to slop oil pressure filtration as a method for sludge volume reduction. This paper examines belt press slop oil recovery, a method currently being practiced which reduces sludge volume while recovering high quality oil. A typical refinery wastewater treatment train usually begins with recovered oil separation tanks where, in the presence of heat, API and flotation unit slop oils can be separated. With time, free oil will be separated leaving a ''rag'' layer of unresolved emulsion of oil, water and suspended solids. This rag layer is treated with organic polyelectrolytes before being dewatered and deoiled on a belt filter press. Operating data from an ongoing application are presented. Chemical costs and recovered oil credits are reviewed, as is recovered oil quality. Monitoring techniques as well as bench modeling techniques are discussed.
