Production of lignin agglomerates

Technology:

This invention presents a process and an apparatus for the production of water-insoluble lignin granulates for material and energetic usage. Pulp extraction for manufacturing paper from wood or grasses generates lignin which has a high calorific value in large amounts as a side-product and component of waste liquor. The further use of lignin is prevented especially because of heterogeneity aroma water solubility dust formation and high reactivity.

Benefits:

This enables in particular efficient utilization of heat and energy
