Abstract: A process for regenerating spent clay which includes: (1) an extraction stage wherein an organic solvent or mixture of organic solvents are thoroughly mixed with the spent clay thus separating the entrained oil from the spent clay, (2) a reactivation stage wherein the oil-free spent clay is treated with acid, and (3) a thermal polishing step wherein the acid-treated, solvent-extracted spent clay is heated at a high temperature from about 500 degrees F to about 1400 degrees F for approximately one minute to five hours, preferably 10 minutes to 4 hours.

Abstract: A process for significantly decreasing processing time, reducing capital costs, increasing yield, improving quality, and improving the safety of refining petroleum residues and sludges generated by the oil producers, refineries and re-refiners comprising the steps of heating under vacuum the petroleum residues and sludges with steam or inert gas injection or both until a temperature ranging from between 680.degree. F. to 1000.degree. F. is attained and holding the mixture at this temperature for a short residence time of from less than an hour to abut 6 hours while vacuum and sparging are being carried out to generate asphalt. Volatile products are condensed to produce fuel, waxy oil and can be further processed to produce refined fuel, wax and dewaxed oil.

Abstract: A process for significantly decreasing the acid sludge settling time in waste oil recovery processes comprising the steps of heating used oil to a high temperature above 725 degrees Fahrenheit, cooling the heated oil, adding an oxidizing agent to the oil, allowing the acid sludge to settle within a period of approximately 24 to 72 hours, separating the acid-sludge-free oil from the acid sludge which settles out of solution as a result of addition of the oxidizing agent, and adding a polishing agent and separating the re-refined oil from the spent polishing agent. The spent polishing agent is recycled, and the acid sludge which settles out after oxidation is converted to either hard, oxidized asphalt or soft asphalt or asphalt products such as emulsions etc. The process produces a high quality re-refined oil rapidly and economically with no acid sludge disposal problem.
