FIELD: gas industry.
SUBSTANCE: invention relates to a method for obtaining a gaseous product (SNG), which includes the following steps: a) obtaining the first part (PF1) of the feed stream (FDS), b) obtaining the second part (PF2) of the feed stream (FDS), c) combining the specified first part (PF1) of the specified feed stream (FDS) with the specified the second part (PF2) of the specified feed stream (FDS) to obtain the specified feed stream (FDS), d) heating at least one of i. the specified first part (PF1) of the specified feed stream (FDS), ii. the specified second part (PF2) of the specified feed stream (FDS) to the stage c), iii. of the specified feed stream (FDS) after step c), e) direction of the feed stream (FDS) to the reactor (RCT), f) transformation of the feed stream (FDS) into a gaseous product (SNG). Step d) is at least partially carried out by compressing the corresponding flow (FDS) with an ultrasonic compressor (SCO) so that the corresponding flow is heated, while the specified ultrasonic compressor (SCO) is driven by a gas turbine (GT) generating exhaust gas (EXG), where the specified exhaust gas (EXG) is used to heat the specified second part (PF2) of the specified feed stream (FDS).
EFFECT: reduced investment and operating costs and a reduction in the area occupied by the device on the surface.
