ENERGY-ECONOMIC RESULTS OF USING THE METHOD OF REDUCING ENERGY LOSSES OF MOBILE DIESEL COMPRESSOR STATIONS BY ADDITIONAL COOLING OF COMPRESSED GASES

The article conducts experimental studies of the use of additional freon cooling systems instead of water systems, which allows reducing the specific consumption of the coolant per kilogram of cooled gas by 2-3 times. For example, for the compressor unit KPU-16/250 the specific consumption of the heat carrier per kilogram of cooled gas when pumping nitrogen for the operating cooling system will be 1.71 kg/kg, and for the designed freon system - 0.69 kg/kg; the specific consumption of the heat carrier per kilogram of cooled gas when pumping air for the operating cooling system will be 1.76 kg/kg, and for the designed freon system – 0.72 kg/kg; When using additional freon systems of high-efficiency cooling for cooling compressed air with a decrease in the temperature of the working medium in gas coolers to -10 0С, the specific energy consumed by the compressor is reduced for diesel compressor units of the oil and gas industry, on average, by 14-17%. Thus, for the SD-9/101M compressor unit, when nitrogen is injected, the specific energy consumed by the compressor decreases from 315.21 kJ/kg to 263.34 kJ/kg or by 16.5%; when air is injected, the specific energy consumed by the compressor decreases from 320.74 kJ/kg to 275.46 kJ/kg or by 14.2%.
