“60,000 ton per year stand-alone facility “

Project Description

The Hauser, Idaho Purcell Wood Pellet Plant is a stand-alone 60,000 ton per year facility. PES was the Engineer for the plant and the supplier for the many components, including the energy system and the dryer for the plant. PES developed the Greenfield 10 acre site, including the county building permits, site infrastructure and the State air quality permit. PES provided technical support to the original owners of the new plant by developing several equipment options for the plant design. Some equipment that was used was originally located in the Atlas Pellet Plant, a smaller pellet plant on leased property in Coeur d’Alene that was forced to relocate.

PES was first hired to evaluate the existing plant for potential use of any equipment that would perform at the new plant’s 60,000 ton per year design rate. Some of the existing plant’s equipment was utilized, but most of the plant was constructed from new equipment. Designed by PES’ experienced technical team, the plant is building on its performance and its reliability to be a long-term economic success.
