This is because of the pos-, sible conversion of possible impurities in the used oil. The, This study aims to reclaim the base oil component of used lubricating oils for reuse. for recycling used lubricating oil, proceedings of RSCE98, Manila, Philippines. Top of Page. Isopropyl alcohol was used as a single solvent, while the composite solvent was made up of ethanol, isopropyl alcohol and toluene. We would like to thank all the members of theInternational Scientific Committee, LocalOrganizing Committee and the students involved for their great efforts in contributing to the success of the conference. Osman et al., Recycling of used engine oil. The whole mixture in a beaker was placed on a magnetic, http://dx.doi.org/10.1016/j.ejpe.2017.05.010. Then it was allowed to stand for, transferred to a rotary evaporator in order to separate the solvents, from the regenerated lubricating oil. To achieve this objective, firstly used oil was allowed to settled for (1hr), after being centrifuged at 1500rpm for 30 minutes then exposed to filtration on Buncher funnel with vacuum pump to remove impurities. Optimization of process parameters for the regeneration of used mobil oil by acid/clay method using sulphuric acid as washing agent was successfully carried out. Carbon dots obtained directly from the ionic liquids, in particular from methyltrioctylammonium chloride (MTOACDs) have demonstrated to be the best candidate as additive in different base oils (0.1% w/v) and lubrication regimes, reducing the coefficient of friction about 30% and wear scar in more than 60% in the most extreme of the tested conditions (120 N). Large quantities of catalysts are used in the Egyptian refining industry for the purification and upgrading of various petroleum streams. 2. You can download the paper by clicking the button above. The design, which use purity as the response of the experiment, considered three independent factors of acid concentration, settling time and bleaching temperature; and the effects of these factors on the response are significant since their P-values are less than 0.05. In 2017 alone, we recovered more than: 90 million. The oil is separated from sludge, then transferred to a evaporator to facilitate the separation of the solvents from the recycled oil. Lube oils are used to, decrease rubbing between surfaces in moving parts. During refining, the chemical, physical and. Contain the oil. Then, the best results were ob- served with isopropyl alcohol as a single solvent and an extraction temperature of 40 °C. oil waste is disposed of directly into the environment, it will cause turbidity, give o a pungent odor, and (some) will solidify and decompose slowly. Bitumen plays an important role especially in the community in terms of infrastructure where its properties are utilized. One of the experiments is to compare the combustion of the revitalized waste oil with the combustion of raw waste oil. In this paper, butanol was selected as an extractant, and monoethanolamine (MEA) as a flocculating agent. In this study, a new type of circulating three-phase fluidized bed reactor was conducted by adding a spiral path and was named as spiral three-phase fluidized bed reactor (TPFB-S) to investigate the possibility for removing engine oil (virgin and waste form) from synthetic wastewater by using Ricinus communis (RC) leaves natural and activated by KOH. Finally the results concluded that TPFB-S has a better performance than the traditional fluidized bed, where the removal efficiency was enhanced by about 23% and 17% for removing virgin oil emulsion from aqueous solution by natural and activated form of adsorbent, respectively. Recycling your used motor oil keeps it out of our rivers, lakes, streams, and even the groundwater. Solvent extraction followed by adsorption has been found to be one of the competitive processes for recycling of waste lubricating oil. The re-purification process for the purpose of dehydration is generally to first heat the waste oil to an appropriate temperature, and then either settle or centrifuge or filter, or combine two of the three separation means, or even use three in combination. Technol. Nevertheless, they show two main drawbacks: most of them are metal-based and, therefore, eco-unfriendly, and they are mostly hydrophilic and, consequently, unstable in organic media, which finally drives to aggregation/sedimentation and the loose of the good properties. Heat reactor by using fuel oil, LPG, natural gas, wood as well as pyrolysis oil. Academia.edu uses cookies to personalize content, tailor ads and improve the user experience. A. Abd, El. A variety of polystyrene‐divinylbenzene resins functionalized with such groups as SO3H, N(CH2COOH)2, and SH were tested in the slurry batch mode for the removal of transition metals from used motor oil. To learn more, view our, A method of predicting effective solvent extraction parameters for recycling of used lubricating oils, Re-Refining of Waste Lubricating Oil by Solvent Extraction, INVITED REVIEW PAPER Re-refining of used lubricant oil by solvent extraction using central composite design method. Step 2: Hydrofinishing. The-, ses processes give different yield and product. It’s easy. Rejection of inappropriate feedstocks. Moreover, it can acts as a cleaning, anticorrosive and cooling agent. Houssien A. Kheireddine, Mahmoud M. El-halwag, Nimir O. Elbashir, Clen In this study, a property-integration framework is used in the optimization of solvent selection for re-refining of used lubricating oils. The most common method for its manufacture is fractional distillation of atmospheric residue from vacuum distillation where waxy distillates are used. Thus, further investigations may be warranted in the future to compare the present studied parameters. Different parameters i.e. After oxida-, tion, most impurities are generated in base oil, during its applica-, tion in internal combustion engine. About 700 mLs of hot oil when pumped through a 37 × 0.9 cm column packed with the Duolite resin could be demetalized to the extent of about 80% if the column was first washed with hexane. It is clear that as the solvent oil ratio increase, the maximum, it is clear that there is a decrease in the oil loss and incre-, for density, carbon residue, ash content, pour point, water, Due to organic, inorganic acids, esters, phenolic com-. Further build up of temperature degrade the lubricating oils, thus leading to reduction in properties such as: viscosity, specific gravity, etc. Lube oil distillates result. Initially, WEO was chemically characterized and then, an optimization of the ECA production was assessed modifying WEO dosages, thermal Motor oil does not wear out—it just gets dirty—so recycling it saves a valuable resource. Therefore, the regenerated mobil oil at these optimal conditions is capable of meeting commercial expectations. Sadeek A. Sadeek, Hoda S. Ahmed, Ebaa A. ElShamy, Hussien A. El Sayed, Asma removal. 23 (2014) 53–60, lubricating oil, Oil Gas Sci. The chemical composition of WEO presents heavy metals dangerous to both then mixed with activated alumina at a proportion of 1:5 alumina. Thereafter, different properties including viscosity, calcium and zinc content, and total base number for determining the degree of treatment of the regenerated oil and waste oil were analysed. The first ISCSC event took place in 2012, and was a real success thanks to participants, speakers and organizers. The tests of FTIR and SEM explained that the adsorbent solid texture consists of negative valences that related to strong and active groups like carboxyl and hydroxyl groups. The more, percent of sludge removal means good efficiency of re-refining, oil, these process is cheaper than refining stages such as vacuum, distillation and finishing stage by alumina adsorption or hydro fin-, ishing stage. Production of Virigin Lubricating Oil from Used Engine Using Solvent Extraction and Adsorption Proce... Regeneration of Waste Lubricant Oil by Extraction–Flocculation Composite Refining. This may be, expressed as the percent sludge removal (PSR) which is the mass, The experimental results indicate that the more effect for, sludge removal capability of solvent mixtures A, B and C as shown, sludge percent (52%) followed by mixture B (36.7%) and mixture C, removed lower percent (18.9%). Dirts and metal parts worn out from the surfaces are deposited into the lubricating oils. An important experimental measurement of the solvent, It is found that mixture A removed maximum, . Motor oils can be re-refined many times. Recycling and reusing used motor oil is better than disposing of it – no matter how proper the disposal method is. The extent of sulphur removal increases in the sequence of Fe/SiO2–Al2O3
