Abstract : The production of olive oil has a huge socio-economic significance in the Mediterranean region. However, the extraction of olive oil generates huge quantities of wastes which have negative impacts on land and water environments because of their phytotoxicity. Olive mill waste water sludge (OMWWS) is one of the major pollutants in olive oil industry. To prevent the severe effects arising from OMWWS, it is necessary to convert this pollutant into useful products such as bio oil, biochar and biogas. Pyrolysis is one of the most prominent thermo-chemical conversion technologies available today because it produces solids, condensable vapors and non-condensable gaseous products at the same time. In our work, pyrolysis of olive mill waste water sludge takes place at 450°C and the products are gradually cooled in two condensers connected in series. Bio oil is condensed in 1st condenser at 90 °C while water vapors are condensed in 2nd condenser at 10°C. A simulation model is developed for the pyrolysis of olive mill water sludge based on the experimental results using Advances System for Process Engineering (ASPEN) Plus. This tool is used here to conduct energy and exergy analysis of the process for each component used in pyrolysis depending upon chemical and physical properties of biomass and operating conditions. As high temperatures are involved in this process especially hot gases, there is a potential of heat recovery for the condensing system using an adsorption cooling machine. Exergy efficiency of the process shows that energy is conserved in the process. Keywords - Energy, Exergy, Pyrolysis, ASPEN Plus, Fluidized Bed Reactor
