Abstract
A new technology for purification of oil from water, salts, and solid impurities with supercritical (SC) CO2 before refining at existing refineries is developed. The proposed technology, along with purifying oil from water, salts, and solid particles, accomplishes its deasphalting and demetallization. The process is implemented on a facility at a pilot plant of the Institute of Petrochemical Processes of the Azerbaijan Academy of Sciences. Preliminary technical-economical calculations show that the energy expenditures on oil extraction with SC-CO2 are significantly lower than for the existing processes.
