Suggestion Petroleum Coke from Iraq Oil Mix. (T-21A+T-5) & PF2 as Alternative Fuel for Cement and Metallurgy

Abstract

The feasibility of utilizing petroleum coke as an alternative fuel for cement kilns and other industries was suggesting. The feedstock using in this study are mixture (T-21A+T-5) Tawke and Shekhan PF2 AT residues were obtained from two Iraqi-Kurdistan crude oils by removing distillates boiling point up to 350°C using the atmospheric distillation unit. The coking processing of AT residues at high temperatures to produce gas, coking distillates and petroleum coke. Coking of AT residues were carried out at temperature 450-460°C and atmospheric pressure, at this temperature, the duration of heat treatment of the feed was 2h. 45 min for Tawke and 2h. 15 min for Shekhan. The choice of temperature and time of the experiments was made on the basis that a lower temperature increases the duration of the process, and at a higher temperature a significant reduction in the duration of the process according to GOST methods, it becomes difficult to obtain the target product with the required content of volatile substances. An increase in the duration of the coking process about 3 hours and more in all cases leads to a decrease in the content of volatile substances. The study was suggested petroleum coke can be using instead of fuel oil on industry effectiveness in cost reduction when switched over from fuel oil to petroleum coke. in the last of this work, after all the measurements and characteristic obtained, two types of treatment scheme were proposed for how to refine these types of crude oils, which give petroleum products with a high sulfur content. The research proposed the technological, ecological and economic aspects of petroleum coke as fuel, including high sulfur content, use as energy in the electrical field (electro energy), and as an alternative fuel for cement production and metallurgical manufacture.
