Alkaline Extraction

 


Online Course Description:
Chlorine is an excellent chemical for pulp bleaching because of its low cost and lignin removal effectiveness. For these reasons, chlorine was traditionally used in the first bleaching stage to remove up to 90% of the lignin remaining in unbleached pulp. Chlorination is the treatment of pulp with chlorine to solubilize lignin and ultimately bleach the pulp. This course discusses the basics of chlorine bleaching chemistry, the purpose of extraction, and the equipment used in chlorination and extraction.
