The project aims to maximise refinery margins at least by $1 a barrel

Chennai Petroleum Corp Ltd (CPCL), a subsidiary of IndianOil Corp Ltd, has got environment clearance for its Rs 3,350-crore expansion project at the Manali refinery near here. Proposed two years ago, the project aims to maximise the refinery margins at least by $1 a barrel. It will produce more high value distillates and enable the company to process more of the cheaper high-sulphurous crude.
