NEW DELHI: State-owned Indian Oil Corp (IOC) today said it has made a technological breakthrough in commissioning a Octomax unit at its Mathura refinery that will help manufacture Euro-VI fuel emission compliant petrol.”The breakthrough technology developed by IOC’s R&D Centre converts C-4 streams from Catalytic Cracker and/or Naphtha Cracker units to high-octane gasoline (petrol) blending stream, thereby enabling compliance with stringent fuel quality norms,” a company statement said.The Octamax Unit has been completed ahead of the targeted schedule and without any cost overrun, IOC said.”The blending octane number of the sample drawn from the newly commissioned unit was seen to be 118, higher than the guaranteed 108, while meeting all other defined product properties,” it said.IOC said Octamax truly is a ‘Make in India’ venture where all activities, from concept to development of the technology, preparation of basic design engineering package, erection and commissioning of the unit, have been accomplished through indigenous efforts.
