Membrane opportunities in lignocellulosic biorefineries

Lipnizki, Frank LU orcid ; Thuvander, Johan LU and Rudolph, Gregor LU orcid (2019) Engineering with Membranes 2019
Abstract
The pulp and paper industry is one of the most important industrial sectors worldwide. The focus of current pulp mills is on the production of cellulose pulp fibres and electricity. By converting traditional pulp mills into lignocellulosic biorefineries they can become a keystone in a future bioeconomy. In order to achieve this, pulp mills have to close their loops and focus on the optimal utilisation of the lignocellulosic raw material not only for fibres but also for the production of biochemicals, biofuels and other advanced materials.Process waters from pulp mills contain various lignocellulosic components such as cellulose, lignin, hemicellulose and extractives and are today send for biological wastewater treatment. An efficient... (More)
The pulp and paper industry is one of the most important industrial sectors worldwide. The focus of current pulp mills is on the production of cellulose pulp fibres and electricity. By converting traditional pulp mills into lignocellulosic biorefineries they can become a keystone in a future bioeconomy. In order to achieve this, pulp mills have to close their loops and focus on the optimal utilisation of the lignocellulosic raw material not only for fibres but also for the production of biochemicals, biofuels and other advanced materials.Process waters from pulp mills contain various lignocellulosic components such as cellulose, lignin, hemicellulose and extractives and are today send for biological wastewater treatment. An efficient separation and concentration of these wood chemicals could be fundamental in utilizing the process waters in future lignocellulosic biorefineries. The pressure-driven membrane processes microfiltration (MF) and ultrafiltration (UF) have been identified as high potential processes for the separation and concentration of lignocellulosic components. This presentation presents the successful implementation of a pilot membrane plant in a thermomechanical pulp mill to recover hemicelluloses. Furthermore, results from fouling and cleaning studies to improve the performance of membrane processes for thus application will be shown. Finally, a cost analysis will underline the great potential membrane processes in future concepts of biorefineries
