Raw Petroleum Coke.

With growing environmental consciousness, Guwahati Refinery, Indian Oil Corporation Limited has also ventured into ecologically friendly fuel and subsequently installed 3 new units: the ISOSIV, the Hydrotreater and the INDMAX. The ISOSIV unit produces Lead Free Petrol by the Molecular Sieve Technology, which separates Octane

rich MS components from feed naphtha. The Hydrotreater Unit (HDT) enables the Refinery to produce High Speed Diesel of very low sulphur and cetane number

Cetane number

Cetane number or CN is a measurement of the combustion quality of diesel fuel during compression ignition. It is a significant expression of diesel fuel quality among a number of other measurements that determine overall diesel fuel quality.- Definition :...

conforming to BIS specifications. The HDT also produces ATF, Superior Kerosene Oil with high smoke point

Smoke point

The smoke point generally refers to the temperature at which a cooking fat or oil begins to break down to glycerol and free fatty acids, and produce bluish smoke. The glycerol is then further broken down to acrolein which is a component of the smoke. It is the presence of the acrolein that causes...

and low sulphur. The Indane Maximization (INDMAX) technology developed by R&D Centre of IndianOil installed at the Refinery is designed to achieve LPG yield as high as 44% through Fluidized Catalytic Cracking of residual feed stocks like Reduced Crude Oil, Coker Fuel Oil and Coker Gasolene. The INDMAX unit also enables Guwahati Refinery to upgrade all its residual products to high value distillate products and make it a zero residue Refinery.
