Total Pulp and Paper Mill Energy Evaluations

摘要

Pulp and paper manufacturing are energy intensive and the second most energy intensive industry group in the manufacturing sector. Energy cost represents ten to forty percent of total manufacturing cost and is an important factor in profitable mill operation. The industry has made large strides in reducing total energy use. A comprehensive approach to identifying energy reduction opportunities has produced excellent results in many pulp and paper mills. Common energy reduction discoveries in evaluations in pulp and paper mills and utilities departments are discussed in this paper. Use of a portable flow meter is a key factor documenting current mill performance and improvement opportunities. There are many unknown measurement surprises in every mill. Total mill energy evaluations include review of preliminary information submitted by mill personnel, separate one-week mill visits for the paper mill and utilities departments and the pulp mill and bleach plant. Recommendations are based and proven technology that has been implemented in other pulp and paper mills.
