Abstract | Full Text

The aim. The aim is to develop the energy efficient technologies to explore hydro geothermal resources of different energy potential.Methods. Evaluation of the effectiveness of the proposed technologies has been carried out with the use of physical and mathematical, thermodynamic and optimization methods of calculation and the physical and chemical experimental research.Results. We propose the technology of integrated exploration of low-grade geothermal resources with the application of heat and water resource potential on various purposes. We also argue for the possibility of effective exploration of geothermal resources by building a binary geothermal power plant using idle oil and gas wells. We prove the prospect of geothermal steam and gas technologies enabling highly efficient use of thermal water of low energy potential (80 - 100 ° C degrees) to generate electricity; the prospects of complex processing of high-temperature geothermal brine of Tarumovsky field. Thermal energy is utilized in a binary geothermal power plant in the supercritical Rankine cycle operating with a low-boiling agent. The low temperature spent brine from the geothermal power plant with is supplied to the chemical plant, where the main chemical components are extracted - lithium carbonate, magnesium burning, calcium carbonate and sodium chloride. Next, the waste water is used for various water management objectives. Electricity generated in the binary geothermal power plant is used for the extraction of chemical components.Conclusions. Implementation of the proposed technologies will facilitate the most efficient development of hydro geothermal resources of the North Caucasus region. Integrated exploration of the Tarumovsky field resources will fully meet Russian demand for lithium carbonate and sodium chloride.
