Abstract

- Process-integrated, continuous, separation of lignin from kraft pulp mills which results in a ligninwith low ash content (0.05-1 %) is relatively new technology compared to traditional kraft pulping subprocesses,like recovery boilers, lime kilns, white liquor preparation etc. The LignoBoost technology wasdemonstrated in 2007 and the first commercial full-scale process started in 2013, delivered to Domtarby Valmet. This means that this concept now has been in commercial scale operation for almost 10years. There is also an alternative commercialized concept available today from another supplier,NORAM International. The idea to integrate lignin separation into a kraft pulp mill is today quite provencommercial technology.This paper will discuss different learnings, experiences, from the early development of theLignoBoost process, which includes handling of the separated lignin followed by drying. The dustexplosion risk is relatively high for dry kraft lignin due to a high kst value – so the paper will also discussif there are opportunities to reduce this risk. The paper will also briefly discuss promising productsegments for kraft lignin.
