Univen Refinaria de Petróleo Ltda is a privately held Brazilian company that owns and has operated a small specialty petroleum refinery in Itupeva, São Paulo state. Established in 1991 as a limited liability company (Sociedade Empresária Limitada), it received ANP authorizations in the early 2000s for processing light crudes, condensate, naphtha, and fractions into fuels including gasoline and diesel, as well as specialty solvents.
The Itupeva facility, with historically modest authorized capacity of around 9,000 barrels per day or less, focused on niche products rather than large-scale fuels production. It is distinct from major state-owned operations and served regional markets in the Greater São Paulo area. Ownership is structured with Vibrapar Participações Ltda as a key shareholder alongside individual João Deguirmendjian, who serves as socio-administrador.
The company remains legally active per official CNPJ records with its registered address at Rua João Batista Pessini, 399, in the Chave neighborhood of Itupeva. However, refining and processing activities appear to have been idled or effectively closed, with no significant throughput recorded since at least 2024 according to regulatory data. The entity continues to exist as a corporate vehicle, though its primary refining operations have ceased.
As a minor private refiner in Brazil's post-monopoly petroleum sector, Univen occupied a specialized position producing solvents and limited fuels volumes before its operational wind-down. It maintains secondary CNAE classification for petroleum refining products alongside administrative services.
Also known as Univen Petroquímica Ltda and Univen Refinaria.
