Pulp and paper

Oxygen to increase the performance of biological reactors and carbon dioxide to control pH more safely and reliably.

Inerting

Increase pulp quality and reduce production costs by reducing bleaching chemicals such as chlorine dioxide as well as reducing biochemical oxygen demand (BOD) and the chemical oxyg ...

Black liquors weak or strong can be treated with pure oxygen in reactors adapted to reduce sulfur emissions and to reduce heat capacity.

Oxygen makes it possible to produce high quality oxidised liquor while reducing costs.

If you produce kraft pulp from pine wood and there is an excess of sulfur in the sodium/sulfur ratio, it may be sufficient to replace some of the sulfuric acid in your tall oil rec ...

If your lime kiln is saturated, the use of oxygen will increase its capacity and reduce emissions of sulfur compounds.

Air Liquide supplies C02 to control pH and reduce chemical and COD loss in the wash.

This process allows the reduction of chlorinated reagents during the bleaching sequence.

Easy to implement, carbon dioxide can safely replace acids such as sulfuric acid, alum, or sulfur dioxide in paper machines to enable better pH control and reduce corrosion.
