GAS PUMPING UNIT Russian patent published in 2022 - IPC F02C3/00 

FIELD: gas industry.

SUBSTANCE: invention relates to gas pumping units (GPU) with high-temperature gas turbine engines as drives. The expected result was achieved in a gas pumping unit containing a gas turbine engine, an inlet device, a compressor, a combustion chamber with a heat pipe and fuel-air nozzles on a nozzle plate connected through a fuel collector with a fuel line, a turbine, a free turbine and an exhaust device, a synthesis gas system that contains a second gas extraction system and an ejector-mixer to which the outlets to the second gas extraction system and the ejector line are connected, a preheating heat exchanger is connected to the inlet to the ejector mixer, installed in the exhaust device, and a final heating heat exchanger with a catalyst is connected to the outlet, characterized in that the ejector line is made in the form of a fuel ejector line, the final heating heat exchanger is installed inside the heat pipe and equipped with synthesis gas nozzles, and the catalyst is installed in the outlet cavity of this heat exchanger, made with an output fairing.

EFFECT: task of the invention is increasing the efficiency of the unit.
