Energy efficiency in pumping systems: Experience and trends in pulp and paper industry
Approximately two-thirds of all US industrial electricity consumption is by electric motors. Pumping systems account for an estimated 27% of this electrical motor consumption. A recent study funded by the US Department of Energy estimates that optimizing the energy efficiency of these pumping systems could reduce consumption by over 20,000 GWh/year using existing, proven techniques and technologies. This study suggests that 22% of the pumping systems savings potential lies within the pulp and paper industry. Energy use analysis being conducted by the US Department of Energy is leading to identification and quantification of savings opportunities within pulp and paper mills. Additionally, Lawrence Berkeley National Laboratory efforts over the past two years have involved extensive contact with the pulp and paper community on motor systems-related issues for the US Department of Energy's Motor Challenge program. This experience has provided an understanding of mill opportunities for improvement through contact with a mill operating personnel throughout the US. This paper examines the applications of pumping systems in the pulp and paper industry, and identifies the most common energy optimization techniques implemented to data. Options such as adjustable speed drives, impeller trimming and multiple pumping arrangements are discussed.
