At the Huajin Aramco fine chemicals and feedstock project — a joint venture between Saudi Aramco and Chinese partners — a 736,000-tons-per-year ethylbenzene unit and a 700,000-tons-per-year styrene unit reportedly held a mechanical completion ceremony on July 2 and have entered pre-commissioning, according to local government announcements and industry media.
The Huajin Aramco project is a large-scale refining and petrochemical complex located in Panjin, Liaoning Province, with total investment reportedly reaching RMB 83.7 billion (roughly KRW 15 trillion). It comprises 32 production units in total, including a 15-million-ton-per-year refinery, a 1.65-million-ton-per-year ethylene unit, and a 2-million-ton-per-year paraxylene (PX) unit. The newly completed styrene unit is reportedly among the largest single units in China, forming an integrated production chain of “pure benzene + ethylene → ethylbenzene → styrene” using upstream pure benzene feedstock and in-house ethylene. The original report does not specify any overseas licensor, so the source of the underlying technology has not been confirmed.
