At its largest refinery, Replan in the 350,800 b/cd Paulínia complex at Sao Paulo, it started up a second coking unit with capacity of 31,000 b/d.
Petrobras also started up a 37,500 b/d diesel hydrodesulfurization unit at the 181,000 b/cd Presidente Getúlio Vargas (Repar) refinery at Curitiba in south Paraná state. The unit, with a hydrogen unit able to produce 270,000 cu m/day, reduces the sulfur content of diesel oil to less than 500 ppm.
