- Background: The statistics indicate high global energy consumption, the world oil outlook report issued in 2017 by OPEC anticipate an increase in oil demand over next 20 years despite improvements in the efficiency-enhancing field and the significant growth of renewable energy. As a result, the environmental impact will be severe. This idea supported with the IEA annual CO2 emissions report, which shows that stabilized status of emissions since 2014 has been broken in 2017. With the context, Iraq has faced enormous challenges within sanctions and local crises which destroyed the energy infrastructure leading to a sharp shortage of electricity. Problem: Iraqi refineries suffer from aging and accumulation of by-products, such as HFO which is burned at the power plants causing severe environmental and economic damage according to international and governmental reports. The thesis discussed the HFO properties based on the integrated analysis among the technical, environmental, economic and political aspects to develop south Baghdad site as a case study. Methodology: The current situation of Dura refinery and South Baghdad SPP have been analyzed regarding environmental impact and Productivity assessment through several published studies. The study work on the possibility of converting HFO into valuable fuel for gas turbine through the gasification theory to obtain a Syngas instead of the direct burning. Because of the difficulties in getting adequate studies and data for HFO and liquids feedstock gasification, the study applied the AHP modeling by using Expert Choice software to simulate the proposed case and to reach the optimal decision by comparing with analytical results depending on the specialized experts survey in this field. The results show that Supplying the syngas to the proposed South Baghdad IGCC will Prevent emitting VOCs, decrease SOx, NOx, and H2S emissions significantly, and decrease the water contamination. Also, Improve the efficiency of the GTs by stabilizing the maintenance period and increasing electricity production. The study recommends ensuring the energy security by investing in the integration between the traditional refineries and GTPPs; this operation is more feasible than deplete the national wealth by importing NG. Also Intensifying R&D on HFO converting to spread the project in other locations which suffer from the same problem.
