Investigation onEnergy Efficiency and Saving Opportunities ofIndustrial Compressed Air systemin ProcessIndustry

Abstract

n textile manufacturing compressed air systems constitute the bulk of energy cost besidesmotor, lighting, fans, pumps and boiler systems. Reducing energy cost through energy efficiency and conservation measures is the clear option for textile industry to reduce overall energy use in ordermake profits and remain competitive.In this research paperenergy efficiency and energy saving opportunities forindustrial compressed air system in process industry is presented.Energy investigation was done to determine power consumption, power factor, power ratings, operation time and other important details of the air compressor for the case study industry. Air leak test was also conducted to determine the extent of percentage air losses by air compressor.The study found potential savings in electric energy to be approximately 157,164 kWh/yearwith simple payback period of 0.3 years. Based on results obtained enormous energy savings could be achieved through implementations of low cost investments such as fixing air leakages and regular maintainance.
