Bongaigaon Refinery & Petrochemicals Ltd (BRPL), a subsidiary of Indian Oil Corporation, has planned to invest Rs.800 crore, mainly to install a new diesel hydrotreater (DHDT.)

The DHDT would be used to help BRPL's petrol and diesel comply with BS-III norms that would come into effect from 2010. The project also involves motor spirit maximization and quality upgradation, besides some minor revamps.

Major portion of investment for these two projects will be from internal resources generation. The Board of Directors has already approved the "implementation methodology" of the project.

Background: BRPL processes Ravva Crude as well as Assam Crude. The diesel produced at BRPL from Ravva Crude meets BS-II specification, which has come into effect from 1 April 2005. The diesel produced from Assam Crude does not meet BS-II specification and is therefore further processed in the DHDT units of Guwahati & Barauni Refinery of IOCL.
