    Abstract: The present invention refers to a method for the regeneration of used petroleum oils which comprises the following steps: (a) demetallization of the used mineral oil by means of chemical treatment of said oil with an aqueous solution of a chemical reagent containing anions which form low solubility salts with the metals of the oil, followed by the separation of the demetallized oil; (b) distillation of the demetallized oil obtained in step (a) at atmospheric pressure and in the presence of alkaline hydroxides; and (c) distillation of the bottom liquid obtained in the atmospheric distillation in step (b) under vacuum and in the presence of alkaline hydroxides to obtain lubricant bases.

    Abstract: Apparatus and process for improved contaminant removal from engine lubricating oil are provided. The invention is adapted for use with an existing engine oil lubrication system and continuously processes a side stream that after processing is returned to the engine oil. During processing, the oil is first filtered and then is deposited to form a thin film upon upper internal surface regions of a heated, generally conically configured platen whose average transverse internal diameter generally decreases with increasing downward distance from said upper internal surface regions. The platen internal surface regions preferably have a plurality of slope changes. Oil so deposited on the platen internal surface regions forms a thin film that flows downwards and preferably experiences a variable flow rate and variable film thickness. Volatiles produced from the thin film are separated and vented preferably from a chamber over the platen, while oil consolidated from the thin film at the platen bottom is collected and recycled.

    Abstract: The invention is directed to a process of reducing the chlorine content of oil as well as its propensity to foul during subsequent distillation processes. The process heats the oil to a temperature in the range of 400 to 700 F and contacts the oil with a non-oxidizing gas, such as steam, for a residence time of at least several minutes. Thereafter the oil may be distilled and/or finished to a base lubricating oil or other distillate product. The oil subject to the process may be used oil, and can be subject to a dewatering or removal of light contaminants treatment prior to being subject to the process.

    Abstract: A method of reclaiming usable stock from used lubricating oil includes passing the used oil through a bed of oil shale containing kerogen. The shale removes impurities from the oil. The shale is then heated to convert the kerogens to shale oil in the presence of hydrogen donor compounds contained in the lubricating oil remaining in the shale. These enhance hydrogen transfer during shale oil production.
