Petróleo Brasileiro S.A. – Petrobras announces that it has started operations at a new Diesel Hydrotreatment Unit at the Paulínia Refinery (Replan), in São Paulo. The operation began three months ahead of the date originally scheduled in the feasibility study, and the project was executed within the approved investment level at the time.
With the start-up of the new unit, Replan increases its production capacity of S-10 diesel by up to 63 kbpd (thousand barrels per day) and jet fuel by up to 21 kbpd. This expansion prepares the refinery for the phase-out of S-500 diesel (500 ppm sulfur), enabling the complete conversion of its diesel production to S-10 diesel (10 ppm sulfur). Additionally, this conversion brings environmental benefits, improving the plant’s energy efficiency and reducing sulfur compound (SOx) emissions from the fleet, which will now use S-10 instead of S-500.
Petrobras remains focused on operational safety, improving energy efficiency, and reducing greenhouse gas emissions, while upgrading its refineries and ensuring competitiveness. Over the next five years, the company plans to invest approximately US$ 15.2 billion to expand refining capacity and position its refineries among the world’s best in efficiency and operational performance.
About Replan Inaugurated in May 1972, Replan is the largest refinery in Brazil in terms of processing capacity, with a throughput of 434 kbpd. The unit accounts for 24% of the diesel market in the country and was named “Refinery of the Year 2024” by the World Refining Association, a globally renowned entity that promotes integration among major companies in the sector. In addition to diesel, the refinery produces gasoline, jet fuel, asphalt, LPG and propylene, among other petroleum derivatives.
