ANÁLISE DA CAPACIDADE DA REDE NACIONAL DE GÁS NATURAL À LUZ DO PLANO DECENAL DE EXPANSÃO DE ENERGIA

Abstract

Brazil is the sixth worldwide economy and directs its energy matrix to use of energy with lower environmental impacts e.g. the natural gas. This study aims at identifying the capacity of the natural gas pipeline network comparing it with 2020 decennial energy plan issued by Ministry of Mines and Energy (2011). The linear programming was used to calculate the network maximum flow. The results show capacity of 213 and 227 MM m3/day at reception and delivery respectively. The current flow represents 75% of idle capacity. It was identified idleness in the Nordeste and Espirito Santo networks and lack of capacity in the Sudeste and Sul networks. Analyzing the 2020 target it was identified idleness in the Nordeste and Espirito Santo network, areas of Vitória, Recife, Rio de Janeiro, Maceió, Aracaju, Salvador, Natal and lack of capacity in the Sudeste and Sul network, areas of São Paulo, Belo Horizonte and Fortaleza. Index Terms - mathematical model, linear programming, network maximum flow, decennial energy plan, natural gas.
