Production of lignin agglomerates

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.
