Dubai’s state-owned Emirates National Oil Company (Enoc) has received technical bids from several countries on the expansion of its Jebel Ali refinery, according to sources familiar with the project.

Engineering, procurement and construction (EPC) proposals were submitted in mid-January. The deadline for commercial bids on the estimated $1bn project is expected to be 20 June. 

The technical bid deadline was pushed back from an earlier cut-off date in late November 2015. 

The brownfield project will add 20,000 barrels a day (b/d) to the refinery’s existing capacity of 120,000 b/d to help meet rising domestic fuel demand.

The refinery currently has two trains of condensate. Enoc plans to add two new processing units – jet and diesel hydrotreaters, and an isomerisation unit – that will lead to the production of Euro V grade products such as high-octane gasoline, low-sulphur jet fuel and ultra-low sulphur diesel.

The front-end engineering and design (feed) study has been completed by US-based KBR, which won the contract for the study in March 2014.

Established in 1999, the refinery processes condensate to produce refined products such as naphtha, jet fuel, reformate, diesel oil, fuel oil and liquefied petroleum gas (LPG) for local and export markets.
