Title: Global warming Case Study: Carbon Dioxide Emissions from Cement Industry in Atbara
Author: Awad, Nuraz Ahmed Mahmoud
Abstract: The objective of this research is to explore the contributions of cement industry to global warming with special reference to the flourishing and rapidly growing Cement industry in Sudan. International agreements were discussed and mathematical models for the representation of climate change were developed. As a case study, emissions of Carbon dioxide from Atbara cement factory were calculated and analyzed through collection of the necessary information on the productivity of the factory, fuel types and the properties of raw materials used in cement production. Molecular weights, used carbon fuel combustion equations and calcinations processes were utilized in the calculation of CO2 emissions. The second method has been used for recalculation with the assumption of pre-heaters addition and the utilization of fuel alternatives. The results obtained revealed that, using natural gas, five stage preheaters and raw materials with low organic subestances contributes the best to the positive performance. The study recommended continuing dissemination of global warming and climate change culture and information to different concerned parties. To reduce the influence and contribution of cement industry to global warming, it is recommended to add a pre-heater to kilns, use natural gas as an alternative fuel instead of furnace, develop alternative cement to replace the costly and pollutant Portland cement. It is also recommended to look for ways and means to minimize carbon dioxide emission or through absorption and use of absolute ethanol or blend thereof.
