Couillard F. T. Tran Université du Québec Environmental Engineering Division, Asian Institute of Technology The process of hot water extraction of tar sand was modified and adapted for removal of heavy oil from bottom tank petroleum sludges, and was submitted to a laboratory feasibility study. This process can also be utilized to clean beach sands contaminated by accidental heavy oil spills. The process mainly consists of a hot-water extraction (digestion), extruding the oil particles from their support of sand or clay. In the case of oil contaminated sands, a single stage extraction yielded a total recovery of hydrocarbons of 99 percent and a clean sand (hardly containing 0.1% of hydrocarbons), thus safe to be returned to the environment. In the case of heavy oil from bottom tank petroleum sludges, it was necessary to proceed with a double stage extraction with the addition of wetting agents: the utilization of Na2 SiO3 aqueous solution of 1 percent in weight was proven efficient, allowing a 82 percent recovery of hydrocarbons, with only 0.5 percent hydrocarbons in the solid residues.
