"The Gujarat refinery is gearing up to meet the petrol and diesel quality improvement programme, in line with the government's auto fuel vision 2025 to supply BS-IV fuels from April, 2017," executive director of the refinery SK Dhar Gupta said.
"There has been no fatality; however there are five cases of injuries to employees of Gujarat Refinery," the company said in a statement issued on Sunday.
India has surplus refining capacity, but there has been maintenance at some plants and petrol demand has risen after a cut in diesel subsidies increased the attractiveness of petrol cars.
State-owned Indian Oil Corp (IOC) will invest about Rs 8,000 crore to expand capacity at its Koyali oil refinery in Gujarat to 18 million tonnes per annum by 2016-17.
State-run Indian Oil Corp, the country's biggest refiner, plans to expand capacity by 87% to 2.46 million barrels per day (bpd) by 2020-21, its head of refineries said.
