Análise da eficiência energética do sistema de ar comprimido em uma planta de processamento de gás liquefeito de petróleo

Abstract

The energy efficiency of a compressed air generation system in a Liquefied Petroleum Gas (LPG) plant was analyzed and it was not possible to evaluate compressed air losses in the distribution network due to the inherent characteristics of the installations. The study focused on the possibility of replacing obsolete equipment with state-of-the-art equipment on the market. The electrical behavior of the equipment that was in operation was analyzed, making evident the wasted energy that it presents. Results have shown that there is an energy loss of approximately 30%. These analyzes, combined with financial analysis studies, simple payback and net present value, have demonstrated that the deactivation and replacement of equipment with more than 30 years of use, bring a financial return in a short time, thus making the project feasible both at the point of Technical view as economic.
