FIELD: power machine building. ^ SUBSTANCE: invention can be used in gas transporting systems for producing electric power, cold resource and liquid fractions of heavy hydrocarbons from natural gas. Feed-power set has vortex regulator to which high-pressure gas main is connected, turbo-expander with generator, condensate collector and mixer. Vortex pipe is made in form of phase-selected vortex pressure regulator. Vortex pipe has supply pipeline connected with screw channel to provide internal positive "hot"-circuit feedback. Height-adjusted tangential nozzle is connected with temperature selection cylinder and with main stream discharge pipeline through diaphragm. Discharge pipeline is connected with pilot unit where temperature selection cylinder is closed with brake chamber. It has cross-piece with profiled blades, which smoothly straighten gas flow and it also has "hot" gas pass-by unit to let gas flow after cross-piece into center of "cold" vortex at axis of temperature selection cylinder. There are phase selectors onto surface of cylinder made in form of adjustable slits disposed along its length according to higher efficiency of removal of heavy hydrocarbons. Cold" output of vortex regulator is connected with separating section and with turbo-expander connected in turn with generator, condensate collector and gas mixer. Output of phase selectors of vortex regulator is connected in series with other input of condensate collector and then with throttle. Output of throttle and the other output of condensate collector are connected with gas mixer. Outputs of liquid fraction of separating section and condensate collector are connected with liquid fraction mixer. ^ EFFECT: improved efficiency of usage of pressure drop energy. ^ 2 dwg |
