Over 98% of sludge volume was salvaged as recoverable hydrocarbon
Hazardous waste reduced from 10,200 bbls (1,621 m3) to less than 100 bbls (15 m3)
The company had been pumping debris/sludge from previously cleaned surrounding tanks, into this tank. The exact contents of the tank were unknown, but were expected to contain paraffin, asphalt, and production sand. Approximately 10,000 bbls (1,589 m3) of sludge was expected.
The sludge removal was done by using roof-mounted circulation tools that carried a proprietary product chemical package (FQE™ Solvent-H) and cutter stock to facilitate the dissolution of the recoverable solids and oil. Over 98% of the sludge volume was salvaged as recoverable hydrocarbon.
The tank was washed and degassed using FQE™ LEL-V leaving the tank clean and vapor free. The insoluble bottoms were processed as non-hazardous solids for landfill application. The volume of hazardous waste was reduced from a projected 10,200 bbls (1,621 m3) to less than 100 bbls (15 m3) of non-hazardous waste.
