Economic technical determination of the energy conversion to Brayton cycle with heat recovery, of Ribaudo S.A.A., enterprise, to reduce electricity costs

Abstract

Ribaudo S.A.A is thermal dedicated to processes and export of fish oil, frozen, canning and fish meal, located in the province of Chimbote - Dept. of Ancash, irrespective to the SEIN, generating their own electricity through two generators consume a 1600KW useful net power. The generator group currently consists of 2 diesel engines with a total consumption of 73, 45gallón/hour, with a unit cost of fuel of 10.5 S/gallon, is the unit cost of electricity generation is 0.4820 S / KW-hour. The plant works in average 3960 hours/year, obtaining a total cost of 3 054 051 S/year. Due to this problem a turbine with the implementation of a regenerative gas was installed to generate their own electric power getting a lower cost of 0.047 KW-hour electric power generation feasible resulting conversion to brayton cycle thermal plant. With the installation of a gas turbine, a regenerator was implemented to increase the temperature of the compressed air, justifying your installation with a saving of 25.61 Kg new natural gas i.e. 40 0000 New Sun /year saved . The regenerator was designed to increase the temperature of the air at 100° C, in the combustion chamber of the turbine to gas, with 1.76 meters in length and 0.8 m in diameter.Gas turbine electric power production was 7 920 000 (KW-hour) year.The net benet of this project is 996 365.72 S/year, with an investment of S/ 1 644 259 recovered from 1.7 years. Then we can say that from the point of view technical, economic and financial, the installation of a turbine to gas with the implementation of a regenerator in the company S.A.A Ribaudo is viable.
