Title: Innovations of Krister Olsson

Introduction

Krister Olsson is a notable inventor based in Karlstad, Sweden, recognized for his contributions to the field of chemical pulp production. With a total of 12 patents to his name, he has made significant advancements in methods that enhance the efficiency and environmental sustainability of pulp mills.

Latest Patents

One of his latest patents is a "Method for generation of clean steam in a continuous digester system." This invention focuses on improving the generation of clean steam in a digester plant of a chemical pulp mill. By utilizing a steam-to-steam converter (SSC) with venting steam from a black liquor flash tank (FT) and chip steaming (SV), the volume of clean steam produced can be increased by over 40-50%. This enhancement ensures that the clean steam meets the preheating needs of chips in the digester system, even under severe operational conditions. Additionally, it allows for a reduction in the total consumption of clean steam from the mill's steam net, enabling its use for other purposes, such as electricity production, thereby contributing to the environmental friendliness of pulp mills.

Another significant patent is the "Cost efficient kraft cooking method using polysulfide cooking liquor." This invention relates to a method for preparing kraft pulp with an increased pulping yield from lignin-containing cellulosic material using polysulfide cooking liquor. The method aims to create a cost-efficient system by charging most of the alkali as heated polysulfide liquor to an initial atmospheric vessel. This process generates steam that provides the necessary steaming effect for the cellulose material while maintaining low temperatures to prevent delignification during the impregnation phase.
