  • Which solvent is used in base oil extraction?
  • Solvent, either single or composite, is used as an extractant. Solvents from the alkane, alcohol, and ketones families are the most popular solvents in base oil recovery, utilized as single solvents or composite solvents [ 73 ]. However, this solvent should have very high purity because impurities in it aect the extraction process.
  • Can solvent extraction be used as a re-Rening technology?
  • This review focuses mainly on solvent extraction used as a re-rening technology, with adsorption as a nishing step. Although solvent extraction gives a well-rened oil, this setup is only useful on a commercial scale. Extracted oil also needs the re-addition of chemical additives to be reused in compatible systems.
  • Which solvent is used for oil recovery?
  • oil recovery, utilized as single solvents or composite solvents [ 73 ]. However, this solvent should have very high purity because impurities in it aect the extraction process. Supercritical ethane [ 74] and supercritical propane have also been used as extracting agents where the above-mentioned solvents do not work.
  • How much oil is recovered from supercritical ethane extraction?
  • The recovered oil ranged from 16% to 55% of the original sludge mass for supercritical ethane, compared to approximately 50% for dichloromethane. The recovered oil from the supercritical ethane extraction was found to comprise mostly saturated hydrocarbons, followed by aromatics, and less than 5 mass% polar compounds.
