Title: Ismo Reilama: Innovator in Chemical Processing

Introduction

Ismo Reilama is a notable inventor based in Reila, Finland. He has made significant contributions to the field of chemical processing, particularly in the treatment of fly ash and the production of chemical pulp. With a total of 3 patents to his name, Reilama's work has had a meaningful impact on the industry.

Latest Patents

One of Reilama's latest patents is a method of treating fly ash from a recovery boiler. This innovative method involves several steps: first, the ash is dissolved in an aqueous solution, and the pH is adjusted with alkali to precipitate impurities. Next, the solution is filtered to remove these impurities. Following this, sodium sulfate is crystallized from the solution, and the crystals are separated by filtering or centrifugation. Finally, the crystallized sodium sulfate can be used as an initial material for producing sodium and sulfur-containing chemicals or as a process chemical.

Another significant patent by Reilama is a method of producing chemical pulp. This method includes treating wood chips or other comminuted ligno-cellulosic fibrous material with a polysulfide-containing cooking liquor at a temperature of 90-145°C. After the impregnation stage, the slurry is heated to cooking temperature to produce pulp with a desired kappa number. Additionally, mercaptide ions are added to the slurry during the process.
