Cost‐Saving Opportunities in the Energy Management of Papermaking Processes

Abstract

Energy consumption optimization belongs to the main agendas in sustainable industries. Here, cost-saving opportunities in the pulp and paper industry as one of the largest industrial energy consumers worldwide are in the focus. Energy-saving measures are proposed employing a large-scale mathematical model of a paper machine based on mass and energy balances supported by real-time experiments in paper machine operation. The presented measures are based on the optimization of paper stock pumping and a drying section operation. The total energy-saving effect of the four proposed measures accounted for a reduction in specific heat and electricity consumption by more than 2 %. The proposed procedures require no or low investment costs with the overall simple rate of return of less than one year.

A Novel Methodology for Developing an Advanced Energy-Management System

“…As proved above, the use of the OC analysis compared to the more conventional Cost-Benefit Analysis [34] or the simpler cost=saving approach [35] can lead to a significantly higher rate of project implementation, as it shows to the top management/decision-makers the loss of monetary gain caused by past lack of action, whilst also indicating the estimated gains that can be obtained if the project is implemented now.

Possibilities of Reducing the Heat Energy Consumption in a Tissue Paper Machine—Case Study

“…Mobarakeh et al [24] developed a model to analyze energy consumption (heat and electricity) and CO 2 emission in the main processes involved in paper production. Janošovský et al [25] analyzed the possibilities of energy savings in a paper machine using a mathematical model based on mass and energy balances. Modeling of the paper drying process was also used by Ghodbanan et al [2].…”
