Direct Applications of Geothermal Energy; Economic and Environmental Assessment: Meshkin-Shahr, Iran

摘要

The city of Meshkin-Shahr is located in Northwestern of Iran, in a region with significant geothermal energy potential. 11 wells (consist of 7 production, 1 reinjection and 3 monitoring wells) have been drilled in the field since 2002. This work evaluates the potential use of separated brine to supply the thermal power demand for the local district heating and industrial use. Separated liquid with 120 °C temperature and 150 kg/s flow rate will be utilized for direct use of geothermal energy. Food processing, district heating, greenhouse, geothermal tourist center and fish farm are the main consumers of this geothermal heating system. Energy and exergy analysis were performed to model the potential direct use. The Economic and environmental analysis was also performed to demonstrate the commercial viability of the project and reduced greenhouse gasses emissions.
