The US’ Kellogg Brown & Root (KBR) has signed up to provide engineering services on feasibility studies on the second phase of the Saudi/Japanese Petro-Rabigh petrochemicals complex on Saudi Arabia’s Red Sea coast.

According to a KBR statement issued on 8 December, it would work on the development of phenol production facilities during the front-end engineering and design (Feed) study process which is already under way. Japan’s JGC is the main Feed contractor on the scheme, and KBR will provide engineering and consultancy services.

The project involves expanding the existing ethane cracker and aromatics complex, which processes naphtha at Rabigh. These two units will produce the basic chemical components that feed the 15 specialist downstream chemical production plants planned by Petro-Rabigh.

According to company documents seen by MEED, Petro-Rabigh intends to process an additional 30 million cubic feet a year of ethane and 3 million tonnes a year (t/y) of naphtha after the expansion.

The first phase of the project, a $10bn integrated refinery and petrochemicals complex which started production in November, produces more than 20 million t/y of petroleum and petrochemicals products.
