Kurbanismayilova A.S., Akhmedov G.Ya. ENVIRONMENTAL ASPECTS OF THE USE OF GEOTHERMAL WATERS IN ARID CLIMATE // Arid Ecosystems. 2023. Vol. 29. № 2 (95). P. 128-135. | PDF
In this article we discuss the problems of inappropriate discharge of spent geothermal waters into the open ground and reservoirs, as well as the release of associated combustible gases with geothermal water into the open atmosphere by flaring. The assessment and possible ways of technical implementation of environmental pollution prevention caused by the use of geothermal waters in arid regions are given. Schematic solutions for the operation of geothermal systems in the mode without salt deposition in the conditions of utilization of associated combustible methane gas are presented. It is shown that the introduction of carbon dioxide into the spent geothermal water that was injected back into the aquifer ensures the durability of the injection wells.
Keywords: geothermal water, associated gas methane, power equipment, ecology, gas utilization, hydrocarbons.
