The Mathura Refinery, owned by Indian Oil Corporation, is located in Mathura, Uttar Pradesh. The refinery processes low sulphur crude from Bombay High, imported low sulphur crude from Nigeria, and high sulphur crude from the Middle East.
The refinery, which cost Rs.253.92 crores to build, was commissioned in January, 1982. Construction began on the refinery in October 1972. The foundation stone was laid by Indira Gandhi, the former prime minister of India. The FCCU and Sulphur Recovery Units were commissioned in January, 1983. The refining capacity of this refinery was expanded to 7.5 MMTPA in 1989 by debottlenecking and revamping. A DHDS Unit was commissioned in 1989 for production of HSD with low sulphur content of 0.25% wt. ( max.). The present refining capacity of this refinery is 8.00 MMTPA.
In January 2009, the plant shut down for a period of time due to a strike.
The refinery was in the news for allegedly causing the white marble of the Taj Mahal to yellow. It is located about 50 kilometers away from the Taj Mahal. It is currently asking the Indian government to allow an expansion, raising the capacity to 11 million tonnes. The refinery also wants to create a new garbage disposal site, which has garnered new outrage from environmental activists because the site will be located even closer to the Taj Mahal and Mathura.The Mathura oil refinery releases toxic gases and disposes waste into the rivers making the area dirty and unhealthy. Even the Taj Mahal is getting affected because of this.  The India government hired a panel to examine the effects of the refinery on the Taj Mahal. The panel found that the air has high levels of suspended particulate matter, caused by factory emissions, dust, construction, and exhaust from automobiles. These are causing the Taj Mahal to change color.
In 1998 the plant was awarded the "Best of all" Rajiv Gandhi National Quality Award.
