Project Detail:
Digboi Refinery of Indian Oil Corporation Limited (Assam Oil Division) is the oldest operating refinery in the country. The original refinery at Digboi came up in 1901 and was rebuilt in 1923. It had an installed capacity of 0.5 MMTPA, which was enhanced to 0.65 MMTPA. After nationalization and merger with Indian Oil Corporation Limited in 1981, the refinery had undergone modernization through the Digboi Refinery Modernization Project (DRMP). In the first phase, crude distillation capacity had been augmented to 0.65 MMTPA with the commissioning of new crude distillation unit (CDU/VDU) in 1996 along with a captive power plant consisting of 3x8.5 MW Gas Turbine and associated offsite facilities. The catalytic reformer unit (CRU) was commissioned in 1997 for production of unleaded motor spirit fuel. In 1999, the new Delayed Coking Unit (DCU) was commissioned and the old Dubbs Coking Unit shut down. The old and outdated wax treatment plants like Acid Washing and Bauxite Filtration have also been replaced by Wax Hydro Finishing Unit (WHFU) in June 2001, and thereby generation of Acidic Sludge has been completely eliminated. The Solvent De-waxing / De-oiling Unit (SDU) and Kero /Diesel Hydro treating Unit (HDT) were commissioned in May, 2003 and December 2003 respectively. The Captive Power Plant was also augmented with a new 20 MW Gas Turbine (GT) and associated 105 TPH waste Heat Recovery Steam Generation (HRSG) facilities.
