Abstract	The treatment and disposal of o i l sludge represents major challenges for oil industries and municipal ities. The oil sludge consumes high portion of oil industries' budget. Several destruction and conventional technologies such as incineration, landfill and biological treaunent have been used to treat oil sludge. However, most of these technologies have not been commercial ly practical due to some limitations including efficiency, ease of operation and cost or not being friendly to the environment. Supercritical Water Oxidation (SCWO) provides a powerful means to transform toxic organic materials into simple, relatively inert oxides. In this thesis, treatment of oil sludge by using SCWO was performed in a micro reactor via a continuous process system at reaction temperatures between 340-460oC and pressures between 200-300 bar in which 340°C and 200 bar are points near the critical point of water, flow rates between 1 -5 ml/min, which indicates reaction times between 21 0 minutes. The effect of operating conditions namely temperature, pressure, flow rate/residence time of the reaction, excess oxygen (02) and initial concentration of oil sludge in the sample were investigated to evaluate their influence on Total Organic Carbon (TO C) removal rate and find out an optimal operating conditions for such process. The results revealed that 99.6% removal rate of TOC can be achieved at both supercritical conditions and near the critical point of water. TOC removal rate remained constant with increase of al l above examined parameters at both
