Techno-Economic Analysis of the Purification/Concentration of Sodium Lignosulfonate Using Membranary and Thermal Processes
Sodium lignosulfonate produced in the wood-pulping sulfite process is a valuable side-product of the pulp and paper industry. Its value can be greatly increased via processing to reduce its water content, and increase its purity with respect to other compounds, such as sodium sulfite and hemicellulo...

| Summary: | Sodium lignosulfonate produced in the wood-pulping sulfite process is a valuable side-product of the pulp and paper industry. Its value can be greatly increased via processing to reduce its water content, and increase its purity with respect to other compounds, such as sodium sulfite and hemicellulose, which could also be valorized subsequently. In this proceeding paper, SuperPro Designer 10 is used to evaluate the theoretical capital and operating costs for using both membranary and thermal processes, with a focus on the product yield and carbon footprint estimations. |
