India’s top oil refiner, Indian Oil, has developed its own refining processes using catalysts and hydro-cracking for converting crude oil into fuels like gasoline, diesel and liquefied petroleum gas. This move may help the firm save at least $1.5 billion in terms of cost. The director of research and development at Indian Oil believes that the firm will soon turn into a technology provider in near future and would not have to be at the mercy of a few multinational suppliers.
