Pumping System Assessment
The Department of Energy Superior Energy Performance Program in conjunction with ASME has recently completed a Standard for performing energy assessments for process heating, compressed air, steam and pumping systems. The Pumping System Standard (ASME EA-2-2009) should be available by early March 2010.
A guidance document was also developed to assist the “specialist” during the pump system assessment process. Said document provides technical background and application details in support of the understanding and application of ASME EA-2-2009, “Energy Assessment for Pumping Systems.” The guidance document covers topics such as rationale for the technical requirements of the assessment standard, technical guidance, application notes, alternative approaches, tips, techniques, and rules-of-thumb; and example results from fulfilling the requirements of the assessment standard.
ASME EA-2-2009 provides a standardized framework for conducting an assessment of pumping systems. A pumping system includes pump(s), driver(s), drives, distribution piping, valves, sealing systems, controls, instrumentation, and end use equipment such as heat exchangers. Assessments performed using the requirements set by ASME EA-2-2009 involve:
-
Collecting and analyzing system design, operation, energy use, and performance data
-
Identifying energy performance improvement opportunities for system optimization.
These assessments may also include additional information, such as recommendations for improving resource utilization, reducing per unit production costs, reducing life cycle costs, and improving environmental performance of the assessed system(s).
While this “Standard” and companion guideline is a huge step forward in developing some sort of strcture for pumping systems we are still missing the mark, that is a Pump System Standard for the design and specification of pumping systems.
My compliments to the DOE and ASME, lets keep the momentum and mitigate inefficiences at the source, in the design phase.
