SULFUR REMVAL FROM BITUMEN WITH SUB-AND SUPERCRITICAL WATER TREATMENT
IntroductionThe current energetic crisis is mainly due to the energy increasing demand (India, China etc.) and politic instability of oil producing countries such as Iraq and Iran. Petroleum dependence could be avoided exploiting other fossil sources of fuel as coal, oil shales and oil sands. Oil sand bitumens have higher concentrations of higher molecular weight species and hetero atomic species containing nitrogen, sulfur and metals than conventional crude oils. Hence, bitumens must be upgraded before being integrated as feedstocks for refining processes. The bitumen from oil sands can be recovered using surface recovery and in-situ thermal processes. The mining recovery methods involve the mining of oil sands and the subsequent extract processing to recover the bitumen from the sand reservoir by aqueous separation 1. However, the severe pollution with water and solvent in bitumen recovery process hinder the wide use of alternate fossil fuel resource as the main energy source. These environmental problems could be reduced by the use of supercritical fluid extraction 2 such as ROSE (Residuum Oil Supercritical Extraction) process developed by Kerr-McGee advocates 3.
