To raise gasoline production capacity to meet the ever-rising demand, some refineries blend harmful chemicals into gasoline, which severely impairs the fuel quality, the head of the Board of Directors at the Iranian Oil, Gas and Petrochemical Products Exporters Union said.
“Of the National Iranian Oil Company’s total gasoline production of 100 million liters per day, 60% are compliant with Euro-4 and 5 emission standards, but the rest [40 million liters/d] is low quality fuel and contains chemicals like benzene, raffinate, naphtha and other aromatic compounds,” ILNA also quoted Hamid Hosseini as saying.
Although adding such chemical products can increase the volume of the fuel, it adversely affects its quality and converts it to Euro-3 fuel that could have a detrimental effect on engine performance, human health and the environment, he added.
