Yanbu Aramco Sinopec Refining Company Ltd. is a joint venture between Saudi Aramco and China Petrochemical Corporation (Sinopec). The YASREF Refinery Project involves the construction and operation of a 400,000 barrel per day (bpd) integrated petroleum refinery in the Yanbu Industrial City located on the west coast of Saudi Arabia along the Red Sea. As a full conversion facility, the refinery will process 100 percent Arabian Heavy Crude, maximizing the resource and producing gasoline, high quality diesel, and liquefied petroleum gases (LPG) as well as byproduct sulfur and petroleum coke for export. The refinery will include process units for the separation and conversion of the feed crude into finished products, utility and offsite systems to support the refinery operation, and associated feed, intermediate and product storage facilities.

YASREF signifies the downstream portfolio added to Saudi Aramco, yet building and cementing on the strategic partnership with Sinopec – Saudi Aramco’s largest crude oil partner and buyer – Both companies bring commercial and technical expertise to the joint venture to enhance trade of transportation fuels between a significant energy producer and its consumer. In addition, YASREF represents a continuing step forward in the strategies of Saudi Aramco and Sinopec to drive growth further downstream to capture additional value along the hydrocarbon chain.


The total amount of product of a refinery process or of all products of all processes of a refinery compared with the equivalent amount of feedstock. A “Refinery Yield” for a given crude oil feedstock and refinery will include a table of amounts of all products derived from a barrel or ton(ne) of crude minus the refinery’s own usage for fuel, flaring and other losses. Since refineries commonly use several feedstocks simultaneously, such a yield is often measured or predicted on the basis of adding incremental feedstock to a fixed throughput.
