Title: Innovations of Mats-Olov Hedblom
Introduction
Mats-Olov Hedblom is a notable inventor based in Avesta, Sweden. He has made significant contributions to the field of pulp and paper technology, holding a total of 3 patents. His work focuses on processes that enhance the efficiency and sustainability of pulp production.
Latest Patents
Hedblom's latest patents include a process for the preparation of cooking liquors having high sulphidity. This invention relates to a method for preparing cooking liquors under reducing conditions for sulphate pulp cooking. The process involves feeding black liquor, after evaporation, to a reactor operating at increased temperatures. This reactor utilizes energy from an external heat source and/or the black liquor itself, resulting in the formation of a sodium sulphide melt that can be further processed into cooking liquor. The invention also emphasizes the importance of maintaining a specific mole ratio of sodium to sulphur in the mixture fed to the reactor.
Another significant patent by Hedblom is for the preparation of sulfide-free alkali liquor. This process starts from a pulp mill alkali sulfide source and involves reacting it in an alkaline medium with copper (II) oxide and/or copper (I) oxide. The reaction is carefully controlled to ensure that the residual concentration of copper ions in the final alkali liquor remains below 1 mmole/l, resulting in an essentially sulfide-free product.
