As the saying goes, “Power saved is Power generated” it is very essential for every industry to reduce andimprove in the field of power consumption as its one of the largest operating cost for any industry and in particular to anair separation unit where raw material is air which is available free of cost from the environment. By applying IndustrialEngineering tools it is aimed to reduce power consumption of an equipment named Main Nitrogen Compressor of an airseparation unit of an xyz company by identifying the scope of reducing power consumption. Main nitrogen compressor isused to increase the pressure of nitrogen by compressing it in three stage centrifugal compressor and this compressednitrogen is sent to booster nitrogen compressor along with medium pressure nitrogen also called Shelf gaseous nitrogen(ShelfGAN) clubbed. The flow of ShelfGAN into booster nitrogen compressor is determined such that net power saving of227.12 kW/hr is achieved for a main nitrogen compressor by adopting a problem solving methodology calledDMAIC(Define-Measure-Analyze-Improve-Control) which is a data-driven strategy, it is implemented by drafting indetail steps in order to shift our focus from the output performance (y) that is MNC power consumption to the rootcauses(x’s). Based on these steps, data pertaining to MNC power consumption is collected and is transferred into astatistical problem ( i .e., mapping x and y) and a statistical solution that is by solving y = f (x) by means of multipleregression analysis and then the statistical solution is transferred into a practical solution.
