Abstract
The environmental impact assessment for the Miravalles Geothermal field establishes the limit for the emissions of hydrogen sulfide at 42 µg/m3 in populated areas and 940 µg/m3 at one kilometer from the power plants, therefore this gas is monitored at populated areas and also around the power plants. This paper compare the results of the computer model Industrial Source Complex (ISC) modeling the effect of the power plants Miravalles I, Miravalles II and Miravalles III simultaneously against the data obtained using electronic instruments for the measurements. The model dispersion can be as short as one hour with three hours being the average time.
