Publication number: 20170283734Abstract: A method for recovering base oil from waste lubricating oil by separating base oil range constituents from a waste lubricating oil mixture, thereafter separating higher quality base oil constituents and lower quality base oil constituents from the base oil recovered from the waste lubricating oil mixture and thereafter treating the lower quality base oil constituents to produce marketable base oil. The total base oil produced from a waste lubricating oil mixture by this process is greater than the quantity producible by previous processes using only base oil separation from the waste lubricating oil mixture or processes which use only treatment of the base oil recovered from the waste lubricating oil mixture to produce the product base oil.Type: ApplicationFiled: June 21, 2017Publication date: October 5, 2017Inventor: Martin R. MacDonald

Publication number: 20170275538Abstract: A method for producing ILSAC GF5 or higher compatible oils from used oil, comprising separating material having a boiling point less than about 350° F. from recovered oil to produce de-volatized fraction and light oil fraction. Separating material with a boiling point greater than about 350° F. and less than about 650° F. from the de-volatized oil fraction to produce fuel oil fraction and heavy oil fraction. Separating material with a boiling point greater than about 1200° F. from the heavy oil fraction to produce partially purified oil fraction and residual fraction. Treating the partially purified oil fraction to separate it into purified oil fraction and contaminant fraction. Hydrogenating the contaminant fraction to remove predetermined compounds, further saturating the fraction and thereby creating a saturated oil fraction. Fractionating the saturated oil stream to produce one or more of naphtha fraction, diesel oil fraction and base oil fraction.Type: ApplicationFiled: June 9, 2017Publication date: September 28, 2017Applicant: Gen III Oil CorporationInventor: Martin R.

Patent number: 6106699Abstract: 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.Type: GrantFiled: April 28, 1998Date of Patent: August 22, 2000Assignee: ProbexInventors: Martin R. MacDonald, Alexander D.B. Daspit, Thomas G. Murray
