DHAHRAN | April 09, 2025

Saudi Aramco and China Petroleum & Chemical Corporation (Sinopec) have taken a decisive step to elevate their joint venture, the Yanbu Aramco Sinopec Refining Company (YASREF), into a new era of petrochemical innovation and integration. Marking YASREF’s 10^th anniversary, the two energy giants have signed a Venture Framework Agreement (VFA) to advance a major expansion of the YASREF complex, strategically located on Saudi Arabia’s west coast in Yanbu.

A Strategic Leap in Downstream Integration

The expansion project is designed to transform YASREF into a fully integrated refining and petrochemical powerhouse. Central to the plan is the construction of a state-of-the-art mixed-feed steam cracker with an annual ethylene capacity of 1.8 million tons, complemented by a 1.5 million tons per year aromatics complex and associated downstream derivatives.

These new facilities will be woven into the existing YASREF infrastructure, maximizing operational synergies and enabling the production of high-value petrochemical products to meet rising global demand.

The YASREF expansion is part of Aramco’s broader $100 billion liquids-to-chemicals program, which includes the development of multiple mixed-feed crackers both within Saudi Arabia and internationally

A Decade of Progress, A Future of Opportunity

YASREF, a joint venture owned 62.5% by Aramco and 37.5% by Sinopec, has been a symbol of dynamic China–Saudi energy cooperation since its inception.

Since commencing operations in 2015 with a crude refining capacity of 400,000 barrels of crude oil per day—expanded to 430,000 b/d in 2020—YASREF has played a key role in Saudi Arabia’s industrial landscape.

The planned expansion is expected to further enhance YASREF’s ability to deliver high-quality petrochemical products, support the energy transition, and foster long-term industrial partnerships between Saudi Arabia and China.
