Technical study - economic power generation - Brayton cycle using biogas for self-sufciency of energy and reduce the boiler fuel company Danper S. A. C.–Trujillo

Abstract

The present study aims to minimize dependence Sein by the company DANPER SAC, installing a turbine Brayton cycle, which exploit the energy contained in the (preconditioned) biomass discarded by the company while reducing the industrial oil consumption No. 6 in the four boilers that currently owns the company. The average annual consumption of S.E. is 4'477,750.00 kwhr The energy contained in the agro-industrial organic waste is refined through biodigesters and purifiers. Biomethane mass now needed to meet US demand was calculated He obtained a now of 0.168 kg / s, then proceeded to select a gas turbine with a power of 2 MWe; It was sized and selected electrical conductors - 1x3x70mm2. After performing energy analysis in the turbine we proceeded to design an air preheater to increase the temperature 80 ° C intake air to the boilers; saving industrial oil No. 6 and reduction of CO2 and SO2 which involves the implementation of the preheater it was determined. The biomethane storage tank was dimensioned for a capacity of 1240.2 ft3, then biomethane purier was selected for a now of 460 Nm3 / h then the type and dimensions of anaerobic lagoons is determined. Finally, the investment costs for fixed assets and the total net profit is calculated by executing the nancial analysis NPV and IRR lar tools; where it was shown that the project is viable.
