Title: Per O Engstrand: Innovator in Energy Efficiency for Cellulose Refining
Introduction
Per O Engstrand is a notable inventor based in Täby, Sweden. He has made significant contributions to the field of cellulose refining, particularly in methods that enhance energy efficiency. His innovative approach has the potential to impact various industries that rely on cellulose-containing materials.
Latest Patents
Engstrand holds a patent for a method aimed at reducing energy consumption during the refining of cellulose. The patent, titled "Method of reducing the energy consumption at the refining of cellulose," describes a process that involves the addition of alkali to neutralize acid groups bonded to the fiber wall. This method measures the pH-value in the pulp suspension at the refiner outlet and adds alkali in a calculated amount based on the measured pH. The optimal range for alkali addition is between 0.05-9 kg/ton, with a preference for 0.5-5 kg/ton, and ideally 1-4 kg/ton, calculated as NaOH. This innovation not only improves energy efficiency but also enhances the overall quality of the cellulose product.
