Question: What is a popular means of recycling or disposing of sludge in hydrocarbon storage tanks?
Keywords: sludge,treatment
Answer: Nalco/Exxon Energy Chemicals has developed a patented process to clean sludge right in the tank. It uses warm water, specialty chemicals and an available diluent to recover 90-99% of the hydrocarbons with little or no hazardous waste; clean sludge is typically ready to be removed from the tank within a few days or weeks.
