TURBO-GENERATOR Russian patent published in 2021 - IPC F25B11/00 F01D15/10 F01D1/02 B01D45/12 B01D45/16 

FIELD: machine building.

SUBSTANCE: invention relates to turbine generators intended for generation of energy at gas-condensate, gas and gas-oil wells due to formation energy, and in particular due to performance of gas produced in wells. Turbine generator is installed near the well in a line from the well to the gas for transportation preparation unit (GTPU). Turbine generator comprises turbine 2 and generator 3 mounted inside main pipeline 1 with high-pressure gas. In front of turbine 2 there are serially and axially arranged swirler 4, liquid separation section 5 and gas-liquid flow extraction section 6 inside main pipeline 1. Suction section of gas-liquid flow 6 is connected by additional pipeline 7 with main flow downstream of turbine 2, and control valve 8 is installed in additional pipeline 7.

EFFECT: invention allows providing independent power supply of oil and gas production facilities, as well as ensuring serviceability of turbine generator in the presence of liquid in gas flow, supplied to input of turbine generator, and when operating conditions of turbine generator change, such as flow rate of inlet flow and electric load connected to turbine generator.
