Diseño de un sistema de cogeneración asociado a la central de generación eléctrica del bloque 18 de PETROAMAZONAS EP

Abstract

The growing global awareness of the efficient use of energy resources has forced governments to re-examine their energy policies and take measures to avoid wasting them. Our country is not the exception with the creation, according to Decree No.1048, of the "National Institute of Energy Efficiency and Renewable Energies", so the present thesis project is in order with this trend of national and global awareness, within a framework of protection to the environment; having as objective to propose a viable economic technical alternative to recover the thermal energy rejected in the form of heat through the exhaust gases of the three (3) Wartsila gensets W16V32 of the Generation Plant (PGE) located in the base ZPF of block 18 of Petroamazonas EP. It will begin by performing an exergy analysis of the exhaust gases of the Wartsila units, to determine the useful work potential that can be obtained from the heat coming from this heat source. Then the thermodynamic design of a HRSG (Heat Recovery Steam Generator) and its support systems, which would recover heat from the exhaust gases of Wartsila units. With the implementation of the proposed system, considering a 95% availability, it will be able to generate a power of 1621 kW and an average annual energy of 1'108.764 kW.h
