A novel tank bottoms and sludge-treatment process, based on a one-of-a-kind three-phase decanter centrifuge, has demonstrated astounding success in treating tank bottoms and various petroleum sludges. The process separates wastes into three product streams: pipeline-quality oil, clean water, and clean, landfillable solids. The operation provides nearly total recovery of the emulsified oil found in the sludge and a complete clean-up of the waste, with no further treatment needed. Unlike other treatment processes, clean-up is often achieved without separation-enhancing chemicals. Revenue from recovered oil discounts the cost of the clean-up, so the venture often breaks even. The economics are more favorable still if the costs of waste liability are taken into account.
Benefits
The fuzzy advisor and control system will help make this technology affordable and available to many operators. The expanded use of this technology has the benefit to the industry and Nation of reducing oil industry wastes (and its associated liabilities) and of recovering salable oil in the process.
