Bío Bío Refinery (Chile)

Weather…

Bío Bío Refinery is located in Hualpén, near Concepción, and stands as the largest petroleum refinery in Chile. Commencing operations in 1966, it is managed by the state-owned enterprise ENAP. The facility is essential for the fuel supply of southern Chile, processing crude oil into a diverse range of products including gasoline, diesel, and heating oil. Its location within the industrial core of the Bío Bío Region allows for deep integration with local chemical and logistical sectors. Recently, ENAP has committed substantial investments to environmental technologies, notably a new wastewater treatment plant and advanced gas desulfurization units. The refinery also operates its own port facilities in San Vicente Bay, streamlining the import of crude oil and the export of refined goods. As a strategic energy hub, the plant ensures market stability and drives significant regional economic growth. Ongoing modernization efforts are focused on meeting and maintaining Euro V fuel standards across its entire production line.
