Revolutionizing Energy Efficiency in Paper Industry

In response to rising energy costs, industrial companies are seeking innovative ways to enhance energy efficiency. A notable example is La Papeterie du Léman, a French paper mill that has managed to save 1 tonne of steam per hour and 12.5 GWh of energy annually with the help of Alfa Laval heat transfer solutions. The company aimed to recover the condensate from their dryer efficiently, which was achieved by using the thermal heat from the condensate to preheat the water in their steam production process. The main challenge was transferring the steam upstream close to the boiler due to its high propensity for clogging. However, with Alfa Laval’s heat exchangers, this issue was resolved, and the project was completed successfully within a year. The heat exchangers, strategically placed at the dryer outlet and where the machine waste goes to the sewage treatment plant, have proven to be the ideal solution for passing loaded fluids and maximizing heat extraction from the condensate without causing clogging.
