Abstract

The area of the Cienega de Chapala is located east rift Citala which houses a geological system that results in the regional hydrothermal activity, mainly Pajacuaran and Ixtlan failures. The regional geothermics consists of a shallow hydrothermal activity consisting of springs and wells of hot water with temperatures between 48 and 94˚C in Ixtlan de los Hervores and San Juan Cosala well as mud volcanoes in Los Negritos. Water and gas hydrothermal manifestations have physicochemical characteristics that indicate the presence of geothermal fluids.

In this paper the Ixtlán de los Hervores geothermal area is studied, interpreting the hydrogeochemical characteristics of the water reservoir through diagrams Giggenbach, it was determined that are waters with high concentration in cation Na (sodium) therefore could be classified as soft water. The Ixtlan de los Hervores geothermal field is considered a reserve of geothermal energy with a potential of 15 MW (in agreement with conventional technologies). Understanding the need for the use of geothermal energy as clean energy to minimize global warming and reducing the impact of climate change globally, a binary thermodynamic cycle for electricity generation is proposed at the present work.

The temperature of fluids on the surface is 98˚C, based on which is proposed the basic engineering for a thermodynamic cycle binary type with a calculated efficiency of 87.67 % in order to give an utilization to the geothermal resource.

Key words: Geothermal field, Power generation, Binary Cycle Plant.
