Feb 01, 2002· Used lubricating oil from vehicles was treated with various types of chemicals to be regenerated. It was found that used lubricating oil could be reclaimed with sulphuric acid, sodium hydroxide, sodium phosphate, ammonium sulphate and rosin. Viscosity and pour point of the reclaimed lubricating oil were improved with the additive …

A used oil centrifuge is an industrial disc-stack centrifuge that exerts over 7,000 Gs of centrifugal force on the oil. This force is sufficient to separate all free water and sediment as small as 0.5 microns.The self-cleaning feature of the centrifuge allows it to eject out the separated solids intermittently while the separated water exits the centrifuge continuously.

Jun 01, 2018· Different recycling techniques have been proposed for refining of used lubricating oils. During refining, the chemical, physical and mechanical impurities are removed with the following processes: distillation, acidic refining, clay treatment and hydrogenation. Theses processes give different yield and product.

Jan 01, 1990· Several reclamation processes have been reported (NIPER, 1987), but the main industrial process used for hydraulic oils and straight (nonemulsifiable) metal working oils is the physical treatment technique (Cukar, 1976). This process generally involves oil dehydration, centri- fugation, filtration, clay contact/hydrofining and reduced pressure ...
