New Delhi: Nayara Energy has commissioned an upgrade of a key diesel-producing unit at its Vadinar refinery in Gujarat. The company said in a statement on Wednesday that the upgrade lets 100 percent of its diesel production continuously meet Bharat Stage VI (BS-VI) emission standards.

The project was a revamp of the refinery’s vacuum gasoil mild hydrocracker (VGO-MHC). A mild hydrocracker converts vacuum gasoil, a heavy intermediate stream from crude distillation, into lighter products such as diesel. Nayara said the revamp strengthens the refinery’s ability to reliably produce cleaner fuels and to support India’s growing energy requirements.
According to the company, the revamp extends the unit’s operating cycle by more than 150 percent. This allows longer periods between planned shutdowns and greater continuity in fuel production and supply, the company said.
Nayara said the project also improves efficiency and crude processing flexibility. It has raised the refinery’s Nelson Complexity Index (NCI) to 12.6, the company said. Nayara had earlier put the refinery’s NCI at 11.8.
Sergey Denisov, Chief Development Officer of Nayara Energy, said: “Despite a challenging global environment, the project was successfully commissioned through a more self-reliant execution approach. This included the installation of a 1,435-ton reactor in a live refinery environment, underscoring Nayara Energy’s ability to safely execute complex refinery upgrades at scale.”

Nayara describes Vadinar as India’s second-largest single-site refinery. It has a capacity of 20 million tonnes per annum. The company said its ongoing investments reinforce its role in advancing India’s energy self-sufficiency and ensuring uninterrupted supply.
