ESTUDO DE AUTOMAÇÃO DE GASODUTOS DE PEQUENAS USINAS DE BIOGÁS

Abstract

The Biogás, also known as swamp gás, is a renewable resource of energy and naturally formed by anaerobic decomposition of organic matter, this process can be optimized by using special chambers that are called biodigestors. There are many processes that can use this and generate electricity, use as substitute for fossil fuel or even sell as carbon credit. But instead they just burn the gas and discard it. It`s low compressibility makes it being transported in gaseous form, unlike LPG, making it harder to occur explosions. This study`s main goal is to create a system of pressure and output control, by changing the rotation of a centrifugal compressor, for small and médium gás pipelines. To reach that goal, and mathematical modeling was elaborated and after that a computer simulation using MATLAB/ SIMULINK.
