Petroleum Refineries, the financial impact due to steam energy leakage is negligible compared to the hourly production disruption. Thus, the steam leak jobs are given less priority than production optimization. However, fuel consumption and environmental impact due to steam leaks lead to new awareness. In a typical Petroleum Refinery, steam energy consumption is about 30% of the total energy mix. The several reports published on steam trap performance evaluation indicate that around 20% of the steam generated in a boiler unit is lost via leaking traps in the steam distribution network (U.S. Department of Energy, Advanced technologies for evaluating the performance of steam traps, federal energy management program). The steam distribution network’s overall effectiveness is vital for Refineries operations, safety, and product yield. The Refineries need proactive methods to minimize steam energy losses via the distribution network. The replacement of defective steam traps with identical ones based on periodic audit reports would not be the best option because of existing pipeline corrosion or previous water hammer effects, or both on the steam traps and pipelines. This paper presents an integrated method to maintain the overall effectiveness of a steam distribution network in a Petroleum Refinery. The integrated methodology consists of correct steam trap installation along with regular preventive maintenance of the steam network. This case study focused on frequent monitoring of high capacity traps and the root cause failure analysis of steam network elements. Finally, evaluation of the overall effectiveness of the steam distribution network has been done as per UNFCCC guidelines (CDM Executive Board, Rev to approved baseline methodology AM0017/Version 02, 22, 2005).
