The refinery, adjacent to an older 660,000 bpd refinery at Jamnagar in Gujarat, has two VGO hydrotreaters of 110,000 bpd capacity each.
The shutdown is for catalyst replacement and will last for about two weeks, the sources said.
A VGO hydrotreater removes sulphur and nitrogen content from heavy feedstock to produce feed for units like fluid catalytic crackers, which produce value added products like liquefied petroleum gas and gasoline.
