POTENSI PENGHEMATAN ENERGI KOMPRESOR MELALUI REPLACEMENT KOMPRESOR MENUJU TYPE AF OPC 55-10

Abstract

Compressors and compressed air systems are important areas for improving energy efficiency in industrial plants. The compressor engine is one of the machines that are included in the top 5 machines with the highest energy consumption. Based on the results of the analysis, the old compressor with a capacity of 90 KW only had a load of 70%, so another 30% wasted energy during the unload condition. The compressor engine which previously used high enough energy was replaced with a compressor engine type AF OPC 55-10 which uses more energy efficiently than the previous type because its capacity is only 55 KW. Through the use of this compressor, the compressor load can reach 90% and is more efficient in energy use. Thus, the potential for energy savings from the utilization of the compressor engine, reaches 306,600 kwh/year. or a potential cost savings of Rp. 442,945,020 per year. With a temperature of 50^oC when operating (load) the motor output power is 193 KW and when not operating (unloaded) at a temperature of 45^oC the motor output power is 186 KW from the nameplate data of 200 KW. The percentage of leaks in the compressed air system on the blow molding machine is > 10%.
