Compressed Air Best Practices - March 2009 - (Page 12) ® | 03/09 Focus Industry ENERGY MANAGEMENT | COMPRESSED AIR AUDIT OF THE MONTH A Steel Cord Producer Manages Pressure Pressure Profile The pressure profile chart shows the pressure gradients that exist from supply to demand. The occasional pressure drops correspond to the HCL or LL pumps coming online. Later we will see that these pressure drops are due to the compressors not responding to the demand. Pressure in the FP area of the plant is consistently 7–8 psig less than the dry receiver pressure in supply. This is due to the flow traveling in undersized piping. The two loops, comprised of 1-inch and 11⁄2-inch diameter piping, are not capable of the flows required in FP. “The audit of this facility has discovered the source of the pressure fluctuations and recommends examining alternatives to the pumps being used that cause these demand events.” HP, which is fed with a 3-inch diameter header, is quite capable of handling all the flow requirements during all aspects of production. This would include all the diaphragm pumps that are used since they are all fed off the 3-inch from HP. Looking back at the chart, you will notice how the pressure gradient from dry receiver to end-of-line at the HP receiver, and even wastewater treatment, are all identical. Pressure draw-downs are felt plant-wide and not isolated to any area. 12 www.airbestpractices.com http://www.airbestpractices.com
