India will switch to the cleanest gasoline and diesel in the world starting April 1
India will join the select league of nations that use gasoline and diesel that contain only 10 parts per million of sulfur, as it seeks to reduce vehicle emissions that are said to be one of the reasons for asphyxiation pollution in major cities.
Sanjiv Singh, president of Indian Oil Corp (COI), the company that controls approximately half of the country’s fuel market, said almost all refineries began producing BS-VI ultra low sulfur gasoline and diesel (equivalent to Euro-VI grade) by the end of 2019 and the oil companies have undertaken the tedious task of replacing every drop of fuel in the country with a new one.
“We are absolutely on track to supply BS-VI fuel since April 1. Almost all refineries have begun to supply BS-VI fuel and the same has reached storage warehouses throughout the country,” he said.
From the storage depots, the fuel began traveling to the gasoline pumps and in the coming weeks all of them will only have BS-VI grade gasoline and diesel, he said. “We are 100 percent sure that the fuel that will flow from the nozzles on all gasoline pumps in the country on April 1 will be fuel that meets BS-VI emissions.”
India adopted fuel equivalent to Euro-III (or Bharat Stage-III) with a sulfur content of 350 ppm in 2010 and then it took seven years to move to BS-IV that had a sulfur content of 50 ppm. From BS-IV to BS-VI it only took three years.
“It was a conscious decision to jump to BS-VI since the first update to BS-V and then switch to BS-VI would have extended the trip from 4 to 6 years. In addition, oil refineries, as well as car manufacturers, they would have had to make investments twice, first to produce fuel and BS-V grade engines and then BS-VI engines, “he said.
The state-owned oil refineries spent around Rs 35,000 crore to upgrade the plants that could produce ultra low sulfur fuel. This investment is above Rs 60,000 million spent on refinery improvements in the previous changes.
BS-VI has a sulfur content of only 10 ppm and the emission standards are as good as CNG.
Originally, Delhi and its adjacent cities would have BS-VI fuel supplies in April 2019 and the rest of the country would obtain the same supplies from April 2020.
But oil marketing companies switched to supply BS-VI grade fuels in the territory of the national capital of Delhi on April 1, 2018.
The BS-VI fuel supply was further extended to four contiguous districts of Rajasthan and eight of Uttar Pradesh in the National Capital Region (NCR) on April 1, 2019, along with the city of Agra.
BS-VI grade fuels were made available in 7 Haryana districts as of October 1, 2019.
Singh said the new fuel will result in a reduction in NOx in vehicles that meet BS-VI by 25 percent in gasoline cars and 70 percent in diesel cars.
The change, he said, is a tedious task since every drop of old fuel with higher sulfur content must be emptied into tanks, pipes and tanks before being replaced by BS-VI.
“We rely on the uninterrupted change to BS-VI supplies throughout the country,” he said. “What we are going to supply is the best quality available anywhere in the world. It does not have a better fuel than is supplied anywhere in the world. Perhaps our BS-VI fuel will be better than the equivalent fuel in some parts of the United States. and Europe. ”
India adopted a fuel improvement program in the early 1990s. Low-lead gasoline (gasoline) was introduced in 1994 in Delhi, Mumbai, Kolkata and Chennai. On February 1, 2000, unleaded gasoline was mandatory throughout the country.
Similarly, the emission standards for BS-2000 vehicles (Euro-I equivalent, BS-1) were introduced for new vehicles as of April 2000. The BS-II emission standards (Euro-II equivalent) for automobiles New ones were introduced in Delhi since 2000 and extended to the other metropolitan cities in 2001.
Benzene limits have been progressively reduced from 5% in 2000 to 1% throughout the country. The lead content in gasoline was phased out and only unleaded gasoline is produced and sold since February 1, 2000.
The gasoline octane number means the improved engine performance. The loss in the octane number due to the gradual elimination of lead was compensated by the installation of new facilities in the refinery and changes in the operation of the refinery. The RON (Research Octane Number) of gasoline for the BS-2000 specification increased to 88. Over time, it increased to 91.
Singh said the reduction of sulfur will reduce emissions of Particulate Matter (PM) even in diesel vehicles of previous generation in use.
