Для эффективной эксплуатации оборудования ГеоТЭС к рабочей жидкости геотермального источника (геотермального теплоносителя) предъявляются повышенные требования. Воз-никает проблема отделения от рабочей жидкости как твердого, так и газового балласта. В статье обосновывается технология использования низкопотенциального геотермальноготеплоносителя и оборудования для отделения растворенных газов и сепарации дисперсной жидкости. Для ефективної експлуатації обладнання ГеоТЕС до робочої рідини геотермального джерела (геотермального теплоносія) ставляться підвищені вимоги. Постає проблема відділення з робочої рідини як твердого, так і газового баласту. У статті обґрунтовується технологія використання низькопотенціального геотермального теплоносія та обладнання для відділення розчинених газів і сепарації дисперсної рідини.

Extraction of geothermal resources – is a complex technological and technical means that provide an output of geothermal energy sources, their transformation and their reinjection of cooled geothermal fluid.In these circumstances, to geothermal heat carrier are required increasing demands. The solid phase that comes from working fluid can cause the accumulation of sediment on the innerwalls of the heat exchanger and the resulting reduction in its performance or even failure. The gas phase in the geothermal fluids is in the form of dissolved gases that accumulate in the underground reservoir mixture of compressed air that is fed into the well for pumping coolant (gas-lift system). Debit geothermal wells, in the case of the gas-lift system increases, but at the same time as a result of reduced density. Therefore there is a need for separation equipment, which is a separate gas phase from the geothermal coolant.
