Energy management technology in pulp, paper, and allied industries

This paper reviews the state of the art and trends in paper and allied industry energy management. As a structural approach, the plant is first partitioned into unit operations convenient for the definition of multilevel control and optimization schemes: The applicable methods of control and system theory useful for energy management are presented. Problems and solutions at each level are identified and discussed. The process of implementation of energy management functions with computers is included along with a summary list of major energy mangement functions. Furthermore, some important optimization examples are presented and several methods are discussed. Although the paper emphasizes power generation and energy recovery area, the research on total mill energy management is reviewed and the main results are briefly presented.
