CRESTEREA EFICIENTEI ECONOMICE IN SISTEMELE DE DISTRIBUTIE A GAZELOR NATURALE

Abstract

The work presents a techno-economic investigation for present solutions for natural gas network rehabilitation in order to find the optimal. There are proposed six representative variants of branched or annular network systems, of medium or reduced pressure realising real combinations having a complexity similar with the system of a medium city. The work performs an evaluation from the energy consumption needed for each variant realisation. It is obtained that differences between the analyzed variants, are bigger that the other from the economical valuation. It is demonstrated that by changing the actual reduced pressure branched network in annular network the maximum flow capacity increases two times and over, generalising the conclusion that by changing the low pressure network in medium pressure network is not necessary the duct sizing in order to take over the new consumers due to the economical development of the region. The proposed innovation consist in a high performance and competitive distribution system, having the final goal clients satisfaction, reliability energetic efficiency and environment friendly.
