Abstract
Thermochemical conversion of oily sludge (OS) from refineries was investigated to evaluate syngas production and its potential use for electricity generation. A preliminary characterization of OS indicated that it has a Higher Heating Value (HHV) of 42.6 MJ / kg, a large concentration of Chromium and Cobalt, Quartz and Cristobalite between its identified crystalline phases, as well as that at a temperature of 80.5 °C it has a viscosity of 8550 mPa∙s. Simulation of an equilibrium model with air as gasifying agent using Aspen Plus 8.6® software was accomplished to analyze the effects of the gasifying agent on OS gasification parameters. As a result of an increasing trend of produced syngas Lower Heating Value (LHV) when equivalence ratio (ER) 0.3 and 10% moisture, reaching a maximum value of 5.1 MJ/Nm3. The OS gasification process could become an added value technological alternative for oily waste treatment from the crude oil refining.
