GAS PUMPING UNIT Russian patent published in 2021 - IPC F02C3/00 

FIELD: gas industry.

SUBSTANCE: invention relates to gas pumping units - GPUs with high-temperature gas turbine engines as drives. Purpose of the invention: increase in the efficiency of the unit. The solution of the stated problems is achieved in a gas pumping unit containing a gas turbine engine, an inlet apparatus, a compressor, a combustion chamber with a heat pipe and fuel-air injectors on the injector plate, connected via a fuel collector with a fuel line, a turbine, a free turbine and an exhaust apparatus, a synthesis gas system containing a second gas collection system and an air collection system from behind the compressor, a mixer ejector, connected whereto are the outlets of the second gas collection system and the air collection system, connected to the outlet of the mixer ejector are two heat exchangers connected in series: preheating heat exchanger installed in the exhaust apparatus and final heating heat exchanger, and a catalyst, due to the fact that the final heating heat exchanger is installed inside the heat pipe and equipped with synthesis gas injectors, and the catalyst is installed in the outlet cavity of said heat exchanger made with an outlet fairing.

EFFECT: increase in the efficiency of the unit.
