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).
