The upgrade will cost Rs 1,850 crore.
Besides, Bharat Petroleum Corp Ltd is spending Rs 390 crore on revamping its diesel/naphtha hydro-desulphurisation units, while Indian Oil is investing Rs 372 crore in petrol quality upgrade project at its Guwahati refinery.
Bongaigaon Refinery and Petrochemicals Ltd is investing Rs 1,431.91 crore in diesel hydrotreatment and Numaligarh Refinery Ltd another Rs 434.94 crore in diesel quality upgrade, he said.
He, however, did not give the timeframe for the investments.
