Grupo Ipiranga is intending to construct a refinery in Brazil in partnership with the Venezuelan PDVSA. The company plans to free the Brazilian petrochemicals complex from the naphtha supplied by state-owned company Petrobras. Currently, the refine capacity of the 11 units held by Petrobras are at their full capacity. The new unit would need investments of USD 1.5 billion and USD 2 billion. The naphtha is processed by Copesul (Rio Grande do Sul), Brasken (ex-Copene) and Petroquimica Uniao (Sao Paulo).
