Araucária Nitrogenados S.A. (ANSA) is a Brazilian fertilizer producer and wholly-owned subsidiary of Petrobras, located in Araucária, Paraná, adjacent to the Presidente Getúlio Vargas Refinery (REPAR).
Founded in 1982 and acquired by Petrobras in 2013, the plant specializes in nitrogen-based products, utilizing refinery asphaltic residue for ammonia production. Its key capacities include 720,000 tons per year of urea, 475,000 tons per year of ammonia, and 450,000 m³ per year of ARLA 32 (Automotive Liquid Reducing Agent). Byproducts encompass CO₂, pelletized carbon, and sulfur.
Mothballed since 2020, ANSA underwent revitalization with a R$870 million investment, resuming ARLA 32 and ammonia output under contract before restarting urea production in April 2026, enhancing Petrobras' domestic urea market share.
