METHOD OF REDUCING FUEL GAS CONSUMPTION BY PARALLEL OPERATING GAS COMPRESSOR UNITS OF BOOSTER COMPRESSOR STATION IN FAR NORTH OF RUSSIAN FEDERATION Russian patent published in 2024 - IPC F04D27/00 

FIELD: gas industry.

SUBSTANCE: invention relates to control of successively operating gas compressor units (GCU) with gas turbine drive (GGCU) of gas compressor shop (GCS) of booster compressor station (BCS) of gas field (GF) of oil and gas condensate field (OGCF), providing mechanized extraction of natural gas. Method of reducing fuel gas consumption by parallel operating gas compressor units of a booster compressor station in the Far North of the Russian Federation includes controlling operation of parallel operating gas compressor units by an automated process control system (APCS) of the booster compressor station. APCS of the integrated gas treatment plant (GTP) continuously monitors in real time the difference in values between the setpoint, the plan of preparation Q_plan of dried gas at GTP for supply to the main gas pipeline (MGP) and its actual value Q_act. Purpose of the invention is to provide for automatic maintenance of the specified plan for preparation of the volume of dried gas Q_plan for the GP, to provide the internal consumers with the dried gas and to achieve distribution of pressure drop of raw gas created by bursts of booster compressor stations with due allowance for their energy efficiency, thus ensuring reduction of volume of fuel gas consumption. Positive effect.

EFFECT: disclosed method enables to automatically redistribute the required volume of compressed raw gas supplied to the inlet of the gas processing unit for preparation of the required volume of dried gas between parallel operating GGCU booster compressor stations in real time at various modes of its operation taking into account the current energy efficiency of parallel operating GGCU, which provides gas processing unit cost reduction for gas preparation for long-distance transport and reduction of carbon footprint during natural gas production.
