25/9/2020, · Different physicochemical and biological treatments have been used to treat oil sludges, and oil recovery techniques are preferred such as oil ,sludge, washing (OSW) with surfactants and co-solvents. Toluene is commonly used as co-solvent, but it is non-benign to the environment. This study tested alternative co-solvents (n-pentane, n-hexane, cyclohexane, and isooctane) at 1:1 and 2:1 C/OS (co ...

Oil ,sludge, washing (OSW) with surfactants and co-solvents is used to recover the oil, and this process leaves some residuals (sediments and surfactant solution). Currently, there are no data on the ecotoxicological effects of these OSW residuals from different sludges. This study evaluated the toxicity of OSW residuals from washing four types of oil sludges with five surfactants (Triton X-100 ...

The advantage of using the ,supercritical, solvent recovery process is the reduction in utility costs. By eliminating the need to evaporate most of the ,extraction, solvent (93% of the ,extraction, solvent can be recovered as a ,supercritical, fluid) the ROSE process also reduces the size and complexity of the plant, saving capital costs.
