The first modern petroleum coke facility was found around 1930s in USA. Between 2007 and 2012 it's production rate increased by 2% in the USA and by 35% in the entire world. According to the 2013 data USA China India Venezuela and Brazil are important manufacturers. Petroleum coke with it's high heating value low ash content and relatively low price among it's competitors is widely used as an alternative fuel especially in recent years. Petroleum coke is primarily and mainly used in power plants and industrial facilities as fuel. Cement factories also use petroleum coke as fuel in their rotary kilns. According to the Turkey Cement Industry report in 2016 it has been used 70% as fuel in these factories. Turkey acts both as an importer and exporter in point of petroleum coke. The 55% of the petroleum coke produced in the world is used in cement industry. In the coming years it's been anticipated that the petroleum coke usage will rise as electricity production increases in countries like China Vietnam and India. Petroleum coke poses an important health risk with it's handling and storage operations. EPA is especially concerned about the particles smaller than 10 µm because those can go into the lungs through mouth and throat easily. Breathing only once these particles go into the lungs and cause severe issues. Thus particle concentrations smaller than 10µm have to be measured in the working area. Exposure to highly concentrated petroleum coke causes inflammatory diseases in the respiratory tract. Repeated exposure can lead to functional failure in the lungs. In the studies no effect on reproductive systems or any cancerogenic effects have been detected. Keywords : Petroleum coke industrial fuel environmental effects cement plants
