Tehran Refinery Enhancing Gasoline Quality to Euro 5

Tehran Oil Refinery will soon start producing gasoline compliant with Euro 5 emission standards, head of the refining company said.
“The refining is producing 7 million liters of unleaded gasoline with octane ratings of 87 (regular) per day. However, completion of a Continuous Catalytic Reformer (CCR) unit and a Reduced Crude Desulfurization (RDC) unit will enhance gasoline quality,” Hamed Armanfar was quoted as saying by ILNA.
Euro 4 and premium gasoline have octane ratings of 91 and 95 respectively. The two units (CCR /RDC) will help increase octane to above 96 and decrease benzene level to less than 1%.
The units are estimated to cost $240 million, he said.
