Title: Innovations in Pulp Production: The Contributions of Mikael Svedman

Introduction

Mikael Svedman, based in Pori, Finland, is an accomplished inventor with a remarkable contribution to the field of chemical pulp production. With a total of five patents to his name, Svedman's work primarily focuses on enhancing the efficiency and quality of pulp processing methods.

Latest Patents

His latest patents include a groundbreaking method for improved turpentine recovery from modern cooking plants. This innovative technique involves transferring spent liquor to pressurized tanks where at least one liquor is expanded in correspondence with a temperature difference of 1 to 5 °C. The generated steam is then utilized for turpentine recovery, leading to effective removal of turpentine and dissolved gases from the liquor. This process not only increases the amount of recovered turpentine but also results in higher quality pulp with better washability.

Another notable patent is the batch process for producing chemical pulp by removing and reintroducing calcium-containing spent liquor in the digester. This method outlines the use of lignocellulose-containing material in kraft pulp production, including the charging and initial treatment with impregnation liquor. During this process, calcium-containing spent liquor is displaced and later reintroduced, enhancing the overall efficiency of pulp production while maintaining high-quality output.
