Lignin recovery from spent alkaline pulping liquors

2019-9-9 · Removal of lignin from the black liquor can allow greater pulp production at such a pulp mill in which the capacity of the recovery boiler system is limited by the calorific load or the solids load (Axelsson et al. 2006; Ohman et al. 2007b; Mesfun et al. 2014).

Kraft Paper (Virgin / Recycled) (Bleached /

With the recovery boiler, kraft paper manufacturers now reach a nearly closed-loop production cycle, meaning they recover and reuse almost all of the water and major chemicals used in the kraft pulping process. The bleaching process renders the paper weaker than unbleached kraft, and it also has a higher price tag. This type of paper is

Chemical Recovery | Industrial Efficiency Technology

For economic and environmental reasons, chemical recovery processes are used in chemical and semi-chemical pulp mills to reclaim spent cooking chemicals from the pulping process. At kraft and soda pulp mills, spent cooking liquor, referred to as "weak black liquor," from the brown stock washers is routed to the chemical recovery area. The chemical recovery process involves concentrating
