It appears they just gave (article below) the Refinery Expansion PM/ED contract to CBI-Lummus who now also does coker technology licensing (they are doing coking unit for Colombia Reficar/Cartagena Refinery).
<FYI – note the Oman Sohar Refinery (current 116MBD expanding to 187MBD+coker?) is not on the OGJ WW Refinery Survey Jan 2011 Capacities & they did not update the Oman Mina Al Fahar Refinery for 2007 expanded capacity of 106MBD. >
This article follows the Jan 2009 presentation which shows a 42MBD Rose/SDA Asphalt unit (along with several others) and does not mention coker option however, the CBI-Lummus award is indication expansion might contain one or at least as a later option.
Past information around the Sohar Alumumin (Rio Tinto is part owner of Sohar Aluminum) smelter expansion/doubling (360MTPY to 760MTPY) indicated Sohar Refinery petcoke would likely be anode type and include a calciner to meet domestic demand. But this news still indicates a SDA asphalt unit instead of coker so perhaps it might be Phase 3 type thing?
