Essar Energy plc [LSE: ESSR], the India-focused integrated energy company, today announced that Essar Oil Ltd has successfully commissioned the Amine Regeneration Unit (ARU), which is a part of the Phase I expansion at its Vadinar Refinery.

When completed, the Phase I expansion will increase the Vadinar Refinery’s capacity from
14 MMTPA (300,000 bpd) currently to 18 MMTPA (375,000 bpd), as well as increase its
complexity from 6.1 to 11.8. The project is nearing completion and increased throughput of 18 MMTPA will commence by March 2012

An optimisation project is also under execution at the refinery to further increase the capacity to 20 MMTPA (405,000 bpd) by September 2012. The capacity expansion, complexity enhancement and subsequent optimisation will give the Vadinar refinery the capability to process nearly 87% ultra-heavy crudes, which are lower cost than light crudes. In terms of product yield, the expanded Vadinar Refinery will have the flexibility to produce higher value products, including pet coke.

Lalit Gupta, MD & CEO-Essar Oil, said, “After the commissioning of the Isomerization Unit
last month, the refinery team is working towards ensuring the commissioning of all the
remaining units that form a part of our Phase I expansion. The ARU commissioning is one
more step in that direction and will be followed by all the balance expansion units being
commissioned in the current quarter.”

The Amine Regeneration Unit (ARU) is a UOP-designed unit, with 8 MMTPA (million metric
tonnes per annum) design capacity. The ARU at the Vadinar Refinery is one of the largest such units in the world. The operational readiness of the ARU is essential to ensure smooth operations of the DHDT (Diesel Hydrotreater) and VGO-HT (Vacuum Gasoil Hydrotreater) units.

The hydrogen sulphide (H2S) generated from the removal of sulphur from diesel and vacuum gasoil is absorbed in a special amine solution in the DHDT and VGO-HT units, respectively.

It is then desorbed out of the amine solution in the ARU unit, rendering the amine usable
again in the DHDT and VGO-HT units.

Essar is the first refinery in India that will use UCARSOL in the ARU. UCARSOL is a
specially formulated amine from Dow Chemicals that helps achieve better efficiency in gas treating and reduces energy consumption
