Methodology for energetic and economic evaluation for the geothermal heat exploitation in an industrial facility

This work aims to analyse the use of low enthalpy geothermal heat in Bahía Blanca by evaluating different alternatives when using it in a specific project. In Bahía Blanca, Argentina, several boreholes with geothermal water have been used for many years. Although there are ageing wells in this area, many of which are proof of the existing considerable geothermal potential, only a few are deemed heat sources. The first section introduces general concepts for the contextualisation of the document. Then, the second section details all the performed methodology and an explanation about the selection of the industrial case is given. Then, the industrial system and pipelines are presented, followed by a description of the mass and energy balances. Later, the heat pump calculous, economic evaluation and CO2 footprint analysis procedures are presented. Finally, the fourth section presents all the obtained results in graphics and tables, and at the end, the conclusions are assessed.
