摘要

To improve the efficiency of the bleach plant's process pumping system, engineers at the Boise Paper mill in Wallula, Washington, implemented a system improvement project in 2005. The plant's process pumping system was evaluated during a course taught by Don Casada, a U.S. Department of Energy (DOE) Qualified Pumping System Assessment Tool (PSAT) Specialist. This assessment was supported by the Northwest Energy Efficiency Alliance (NEEA), and results were later corroborated by Tim Dugan of Compression Engineering Corporation in an evaluation funded by the mill's electric utility, Pacific Power. This project greatly improved the plant's process pumping system efficiency. Based on measurements of the system's use, the project yields approximate annual electricity savings of 498,000 kWh, electricity cost savings of $15,157, and maintenance cost savings of $2,500. An incentive from Pacific Power brought total project costs to $74,000, resulting in a 4.2-year simple payback.
