Seasonal Variations in Wood: Percieved and Rea Impacts on Pulp Yield
Source abstract
Abstract
Over the course of a year, mills experience substantial variations in reported pulp yields per green ton of wood. In the spring, more wood must be consumed to produce the same amount of good-quality pulp. This paper examines the extent of seasonal changes and the seasonal reproducibility of wood moisture in chips. Seasonal changes in the amounts of bark, pin chips, and fines in the chips going to the digester are also examined. Other potential seasonal accounting impacts on reported pulp yield and costs are also considered. Assuming a 1000-TPD mill with a nominal wood cost of $45/green ton, these seasonal changes can account for a variance of almost $600,000/month between the best and the worst operating month. In the worst month, an additional 0.5 green tons of wood per ton of pulp must be processed.
