Mumbai : Essar Oil has announced the completion of its 8,300-crore rupee expansion of its Vadinar oil refinery in Gujarat that will boost company’s turnover by 30 to 35 per cent, besides improving margins.

Vadinar Refinery is now India’s second largest single-location refinery, with an annual capacity of 18 million tons, up from 14 million tons currently.

The capacity expansion and complexity enhancement gives the Vadinar Refinery the capability to process much heavier crude, which is cheaper.
