The existing refinery is currently the largest operating refinery in Russia.

CB&I’s project scope includes FEED development for multiple new process units, including a two million ton per annum hydrocracker unit licensed by Chevron Lummus Global (CLG), as well as hydrogen, sulfur and other associated units.

"CB&I has been selected for this significant project following the successful delivery of a similar hydrocracker complex earlier this year for Gazprom Neft in Pancevo, Serbia," said Philip K. Asherman, CB&I’s President and Chief Executive Officer.

"CB&I appreciates Gazprom Neft’s confidence in our ability to deliver results and is fully committed to meeting our client’s expectations on this important project."
