The article discusses energy-saving technologies and the efficient use of secondary energy resources at the enterprises of the oil and gas industry. Calculations show that, due to the introduction of regeneration (plate regenerator), the heat of exhaust gases, fuel gas saving, compared with no regeneration, efficiency can reach 30-40% with a regeneration factor of 0.80-0.90. Increasing the efficiency by 5%, for example, for one unit of a gas turbine unit will save 140-180 m3 / h of fuel gas or 0.9-1.1 mln. m3 per year. For promising gas turbine installations, the coefficient of efficient use of fuel heat can reach up to 80% and higher; of them for the increase in power on the shaft of the supercharger 35-40%, and the rest due to the rational use of the heat of exhaust gases
