NOVEMBER 12 - 2007

Axens has recently been awarded several major basic engineering design packages and technology licenses for new, Clean Fuels Programs with IndianOil. The contracts are for the following refineries: Guwahati, Barauni, Mathura, Digboi, Panipat, and Paradip refineries. Commissioning of the units is scheduled for 2010 when the Euro IV equivalent specifications come into force in India.

The one million ton per annum (1 Mtpa) Guwahati, and 0.65 Mtpa Digboi refineries will install 45,000 tpa C5/C6 deisohexanizer (DIH) configuration isomerization units to provide a high octane component for the gasoline pool.

A major gasoline pool upgrading project will be undertaken at the 6 Mtpa Barauni refinery with the addition of a 322 000 tpa Prime-G+™ unit to desulfurize fluidized catalytic cracked (FCC) gasoline to less than 100 ppm sulfur, a 126 000 tpa C5/C6 DIH isomerization unit, and a revamp of the existing catalytic reformer unit to a capacity of 300 000 tpa of reformate.

The 8 Mtpa Mathura and 12 Mtpa Panipat refineries will add new 525 000 and 370 000 tpa Prime-G+ units respectively to treat their FCC gasoline stream to less than 100 ppm sulfur.

In addition, the new, 15 Mtpa grassroots Paradip refinery has selected HyC-10™ technology. This 105 000 tpa unit enables the desulfurization, with mild conversion, of vacuum gasoil (VGO) feed to an FCC unit with simultaneous improvement in the quality of the diesel fraction. The FCC VGO feed sulfur content is reduced to 700 ppm, which enables better operation of the FCC and higher gasoline yields. The sulfur content in the diesel cut is reduced to 10 ppm.
