NextGen motor oil is the culmination of years of research, technology and innovation from Valvoline scientists coupled with industry improvements in the oil re-refining process. In the past, recycled oil often meant passing used product through an acid clay treatment (think pouring coffee through a filter), a process that removed some ...

Increased use of additive packages in the formula on of lubricants and by consequence higher level of contaminants in the used oil. Increased amount of thermal degradation products due to longer mileage of the lubricants. Pollution problems related to the disposal of acid sludge and spent clay from the traditional acid/clay re-refining.

Acid/Clay Refining is the treatment of crude oil distillates (fractions) with sulphuric acid or their chemicals. The process initially improves the color and aging tendencies, and also increases the density and viscosity index of the oil. The use of acid/clay refining processes is limited to the manufacture of some white oils and sulphonates as ...

fresh oil is C and used engine oil is C. is decrease in pour point is because of degradations of additives, which were present in fresh oil as pour point depressants. Pour Point values of re ned engine oils by composite solvent, single solvent, and acid treatment are C, C, and C, respectively. ese results show that the two methods

Zealand Dominion Oil rerefines about 7 million litres per year, while an older acid clay method is used at Turua near Thames to treat 0.5 - 1 milion litres per year. Most of the sceptics regard the process as some sort of simple filtration. In fact, the re-refining process used at Dominion Oil is a highly sophisticated operation using the most

Abstract. This report compares the economics of acid/clay re-refining with the economics of the BERC solvent re-refining process. The costs of re-refining using the BERC process have been studied in a previous report entitled ''Predesign Cost Estimate for Re-refined Lube Oil Plant'' prepared for the Bartlesville Energy Research Center.

from 25.5 for used lube oil to 86.2 for distillation, 89.10 for acid/clay treatment and 80.5 is for activated/clay treatment. This is compared with 92.8 cs for fresh lube oil. Other results from the different tests showed varied degrees of improvement with the best …

Acid-clay has been used as a recycling method for used engine oil for a long time. This method has many disadvantages; it also produces large quantity of pollutants, is unable to treat modern multi grade oils and it is difficult to remove asphaltic impurities.

In terms of process, the re-refined base oil market can be segregated into acid & clay treatment, propane extraction, flash distillation, and de-metallization & hydro-processing. De-metallization & hydro-processing is a leading and sophisticated process known to achieve base oils of high API grades, usually group II and group II.

conversion of waste oil to a product with similar characteristics to those of oil. The process typically involves, but is not limited to, pre-treatment by heat or filtration, followed by either vacuum distillation with hydrogen finishing or clay, or solvent extraction …

The cleaned oil is then subjected to catalytic hydrogen treatment, affording a dried, regenerated base stock oil, to which a manufacturer can then add desired additives to produce a finished product. A "Down-Home" PROP Process. My grandfather once told me that motor oil never wore out, it only got dirty. He used to recycle his motor oil in the ...

This research investigated the effect of three different acids (sulphuric acid, hydrochloric acid and nitric acid), on three different clay deposit samples, to recycle used lubricating oil. To achieve this objective, filtration of the used oil was carried out first to remove impurities like: sand, metal chip and other micro impurities using: Buncher funnel, filter papers and vacuum pump.
