Thermodynamic and economic analysis of a geothermal trigeneration energy system, integrated with the Flash cycle, Kalina cycle and Stirling
Main Article Content
Abstract
In the present investigation an analysis of the thermodynamic and economic performance of the Kalina cycle, Flash cycle and Stirling engine, is made, integrated in an innovative way to take advantage of the geothermal resources in power generation. Setting up a model based on the first law of thermodynamics, with the objective of presenting the net power output of each cycle and the Stirling engine. The results indicate a net power output of 31.35MW from the system, which compared with other methods to obtain energy, in terms of power is relevant. On the other hand, through an economic model based on economic indicators, is concluded that the system has a favorable economic viability with a return of investment in 1.5 years, and a net value of 139,100,000 USD.
