INDUSTRIAL GASES (CARBON DIOXIDE, OXYGEN) FOR THE PULP & PAPER INDUSTRY

Carbon Dioxide
Carbon dioxide is an industrial gas used in the pulp and paper industry to control pH levels, enhance pulp yield, and wash brownstock and bleached stock.

Oxygen
As an industrial gas, oxygen helps you meet stringent environmental regulations through use in delignification, oxidative extraction and wastewater treatment.

PRAXAIR INDUSTRIAL GAS APPLICATIONS FOR THE PULP AND PAPER INDUSTRY

Brownstock Washing
Increase production rates for bleached pulp with our brownstock washing and recovery system. CO2 acidification of brownstock washers is a reliable, low-capital solution that can provide multiple performance enhancements.

Wet End pH Control
Control pH with carbon dioxide in the stock preparation and wet end stages of your alkaline, neutral and tissue paper making processes. Lower maintenance cost and reduce acid handling by using carbon dioxide that is non-corrosive.

Delignification & Chlorine Reduction
Oxygen delignification can reduce chlorine requirements in the bleach plant and has been recognized as one of the strategic technologies which offer yield enhancement in pulp production. Other peroxide and oxygen applications can reduce chlorine usage.

Bleaching
Ozone bleaching, combined with oxygen delignification and other non-chlorine bleaching technologies, can assist mills to meet environmental standards cost effectively.

SERVICES FOR PULP AND PAPER COMPANIES

We do more than provide industrial gases and applications to the pulp & paper industry.
