7.2.5 Special products in NER refineries<br />

Indian Oil Corporation Ltd (IOCL)<br />

Due to their smaller size, refineries in the Northeast face high operating cost compared with larger<br />

refineries elsewhere in India. To make these refineries more profitable, opportunities of producing<br />

value-added specialty products should be explored. Some of the areas that are being studied are:<br />

Digboi: Revamp of DHDT, paraffin wax, CRMB/hybrid bitumen, calcined petroleum coke/<br />

needle coke, naphthenic base oil<br />

Guwahati: CRU installation, petcoke fired boiler, needle coke<br />

Bongaigaon: IndMAX, revamp of ISOM unit, CRU/DHDT capacity expansion, calcium carbideacetylene-PVC<br />

and production of special boiling point solvents<br />

Production of value-added specialty chemicals will not only improve profitability of refineries, it will<br />

also help in setting up new downstream units, thereby helping economic development. Emphasis,<br />

therefore, needs to be given to these refineries for production of specialty products.<br />

In addition, Guwahati refinery’s installation of a pet coke-fired boiler of 80 TPH capacities for reducing<br />

power cost is under approval.<br />

Bioethanol<br />

Bioethanol is a bio fuel made from feedstock such as grains, sugar beets, bamboo, rice-husk, straw<br />

etc. It is one of the most frequently used biofuel that can be mixed with petrol in varying proportions<br />

depending upon norms in the country.<br />

The USA is the largest producer of bioethanol followed by Brazil and China. The figure below shows<br />

the major producers of fuel grade bioethanol and their production in 2014.<br />
