VADINAR (GUJARAT) — Nayara Energy said on Thursday that it has commissioned the revamp of its VGO-MHC (vacuum gasoil mild hydrocracker) unit at the Vadinar refinery, enabling 100 per cent of the plant's diesel production to continuously meet BS-VI emission standards.

Vadinar, in Gujarat's Devbhumi Dwarka district, is India's second-largest single-site refinery, with a capacity of 20 million tonnes per annum. The company said the upgrade strengthens the refinery's ability to reliably produce cleaner fuels and support India's growing energy requirements.

The project extends the hydrocracker unit's operating cycle by more than 150 per cent, allowing longer runs between planned maintenance shutdowns and greater continuity of fuel production and supply. It also improves efficiency and crude-processing flexibility, raising the refinery's Nelson Complexity Index to 12.6, Indian Chemical News reported, carrying the same company figures.

Sergey Denisov, Nayara Energy's Chief Development Officer, said the project was commissioned through a more self-reliant execution approach despite a challenging global environment. That included installing a 1,435-tonne reactor inside a live, running refinery — a step he cited as evidence of the company's ability to safely execute complex refinery upgrades at scale.

The Rosneft-backed company said it has also adopted a phase-wise asset development strategy for the Vadinar complex. The commissioning means one of India's biggest fuel suppliers can now keep its entire diesel output at the cleaner BS-VI grade without interruption, while spending less time shut down for planned maintenance.
