The case study of energy flow analysis and strategy in pulp and paper industry

The pulp and paper industry is a significant consumer of fossil energy in the Taiwanese manufacturing sector. The concentration of greenhouse gases (GHG) from manufacturing factory activities and vehicle emissions has increased remarkably. Notable energy savings can be achieved in the pulp and paper industry through energy flow analysis. The aim of this paper is to analyze the energy flow for three major energy consuming mills of the pulp and paper industry in Taiwan to make energy savings. In addition, potential technology options are examined for the capture of some of the energy that is currently lost in the processes and to identify the areas of energy saving potential that could have a large impact across more than one industry. The results of this study can serve as a benchmark for developing a quantified list in terms of energy savings potential and opportunities for improving the efficiency of the pulp and paper industry.
