METHOD OF ASSOCIATED OIL GAS RECOVERY AND POWER MACHINE TO THIS END Russian patent published in 2013 - IPC F02C1/02 

FIELD: machine building.

SUBSTANCE: proposed method comprises feeding air and associated oil gas into power machine, mixing them and igniting to obtain heated working body to convert its heat into pay load. Portion of air fed into power machine is heated in heat exchanger arranged inside said machine in its high-temperature combustion of associated oil gas, expanded in the turbine and directed in associated oil gas feed zone for mixing and combustion in medium of preheated air. Work of heated air expansion is exploited in turbine for compressor and pay load extra unit drive. Power machine comprises housing composed of discharge flue with inlet and outlet communicated with atmosphere, impeller machine articulated with pay load unit, combustion chamber and atmospheric air and associated oil gas feed elements. Additionally, power machine incorporates heat exchanger, extra impeller machines and pay load extra unit, all being articulated to make turbo compressor. Inlet of the latter is communicated with discharge flue inner space at its lower section while its outlet is communicated with turbine inlet via heat exchanger cold section arranged in high-temperature zone of combustion chamber. Turbine outlet is communicated with discharge flue inner space in zone of combustion chamber associated oil gas feed point.

EFFECT: higher efficiency.
