Source-derived summary

The Vadinar Refinery is an oil refinery at Vadinar, Gujarat, India. It is owned and operated by Nayara Energy Limited, in which Rosneft owns a 49.13% stake. The refinery is India's second largest single-location refinery, with an annual capacity of 20 million tonnes (405,000 barrels per day) and a complexity of 11.8, which also makes it among the world's most complex refineries.

History

Construction of the refinery started in 1996 by Essar Oil. The refinery project was delayed several times due to environmental concerns and financial problems, including initial cost overruns and a shortfall in equity contributions. In 1998, when the refinery was 60% complete, a cyclone struck the plant and caused considerable damage. Construction was restarted in 2005, and the refinery was completed in 2006. It cost US$2.14 billion.

In May 2008, Essar Oil reported commercial production of 10.5 million tonnes per annum (mtpa). The units commissioned in the first phase were the CDU, VDU, sulfur gas unit, naphtha hydrotreater, catalytic cracker, and Vis breaker.
