Abstract The effective disposal of ,oily, solid waste has received widespread attention due to its complex combination of various petroleum hydrocarbons, water, heavy metals and solid particles. Removal/recovering oil from such waste can be a feasible option. In this study, a subcritical water ,extraction, (SWE) process was used to remove and recover oil from oil-contaminated soil.

A bench-scale apparatus was used for the low-temperature thermal desorption (LTTD) treatment of oil-based drill ,cuttings, (OBDCs). The effects of treatment temperature, treatment duration, sand/OBDCs mixing ratio, and initial oil content on the LTTD treatment performance were investigated. It was found that the petroleum hydrocarbons (PHCs) were barely left in the high-oil-content drill ...
