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.  The aim of this work is the scientific and technical justification based on experimental studies of complex hydrodynamic processes at downstream and cross movement of gas-liquid and onthis basis to develop methods of calculating energy efficiency separation apparatus.The study of the gravitational motion of liquid film carried on the work site, which was the channel without mesh coating and coated.As a result of experimental studies of flow pattern obtained in the working area, which is the element separation device. To determine the field of a sustainable separation device for installation presented research was carried out hydrodynamic processes at work sites, which modeled element channel separationdevice.A separation process to intensify and expand the boundaries of the stable range, which remains the most effective plan of the two-phase flow using vertical channels of capillary-porousstructure.
