Industrial gases (carbon dioxide and oxygen) for the pulp and paper industry

Carbon DioxideCarbon Dioxide rollover carbon dioxide

As an industrial gas, carbon dioxide can be used in the pulp and paper industry to control pH levels, increase pulp yield, and clean unbleached and bleached pulp.

OxygenOxygen rollover oxygen

As an industrial gas, oxygen can help users meet strict environmental protection regulations when applied to delignification, oxidative extraction, and wastewater treatment.

Industrial applications and solutions for the pulp and paper industry

Wood removal and bleaching

Praxair's industrial solutions for oxygen delignification and ozone bleaching can be used for the production of fully chlorine-free pulp.

washing

With our coarse pulp detergent recovery system, you can increase bleached kraft pulp productivity to 15%.

shield

Use carbon dioxide instead of sulfuric acid to treat the asphalt composition of the shielded room. Carbon dioxide treatment is safer and does not cause corrosion in shielded room equipment.

White liquor oxidation

Praxair oxygen can be used to promote the effective oxidation of white liquor-a source of alkali, which is very useful for bleaching and delignification processes.

Wet-end pH control and adjustment

Carbon dioxide is used to control the pH of the preparation and wet-end stages of the alkaline, neutral, and tissue papermaking processes.

Industrial services for the pulp and paper industry

Praxair not only provides industrial gases and applications for the pulp and paper industry, we also provide high-performance surface coating products that can handle wear and corrosion issues and improve the various rolling properties of paper. Our high-resistance coating increases surface finish and gloss and improves roll life during grinding, ultimately reducing costs and improving paper quality.

Praxair works with you to optimize the entire process. From consulting to implementation and practical use, Praxair provides you with a complete set of industrial services to help manage gas supply and protect products, ultimately increasing production efficiency.
