Compressed Air Savings

Plant has two industrial connections in adjacent sheds with two independent electrical connections. This plant has 22 kW @ 127 CFM compressors feeding independent ring main circuits. Several air leakages were observed during audit. Compressor loading on plant 1 was marginal and poor loading on plant 4 compressor. Percentage energy consumption share was 34 % and 82 % respectively.

Benchmark Energy Consumption

Plant I have observed 33 % and plant IV has 16 % of air leakages in the whole consumption, the air leakages are major source of energy loss. Plant should arrest all air leakages in the plant and it will be reducing the demand of air usage. After this arresting of air leakage plant can run the both plants only on one compressor

Loading on the both the compressor is marginally poor as we can see in Utilisation graphs, there is certain amount of unload in both the compressors. Plant IV compressor is majorly in unload condition and it is contributing more in the daily consumption of plant IV. This is due to the unload power of compressor. After arresting air leakages from both plants, Management can think of combining both compressor load on single compressor
