Pulp & Paper
During the pulp delignification process, oxygen is used to eliminate lignin which in turn helps in increasing the brightness of the paper thereby reducing the amount of chemicals required during multiple bleaching cycles. Not only this helps in reducing the environmental impact of bleaching chemicals but also provides direct monetary procurement cost savings of bleaching chemicals.
Bleaching is the process of lightning the color of the pulp through chemical treatment to get a brighter, stable and smoother paper. With the help of oxygen during delignification stage, the output paper quality is improved with a reduced impact on the environment.
Key Applications
Oxy-Bleaching
Oxygen replaces chlorine in eco-friendly pulp bleaching processes. It improves brightness while reducing harmful byproducts.
Pulp Delignification
Oxygen is used to break down lignin in wood pulp. This enhances paper quality and reduces chemical usage.
Challenges
Minimizing the environmental impact of bleaching chemicals
Reducing procurement costs for chemicals
Maintaining consistent process quality
