Introduction:
Asia Chemical Engineering Co., Ltd. is one of the most reliable manufacturers and suppliers of caustic soda plant for pulp and paper in China. Please rest assured to wholesale cost-efficient caustic soda plant for pulp and paper from our factory. Good service and reasonable price are available.
What is Caustic Soda Used for in Pulp and Paper Industry?
Caustic soda (sodium hydroxide) is one of the most important chemicals in paper manufacturing.
It is mainly used in:
Kraft pulping process (wood chip digestion)
Lignin removal from cellulose fibers
Paper bleaching process
Recycled paper de-inking
pH adjustment in pulp processing
Wastewater treatment in paper mills
Without sodium hydroxide, efficient pulp production and fiber separation would not be possible.

FAQ
1、What role does caustic soda play in the pulp and paper industry?
Caustic soda is used in the pulping process of kraft paper to break down lignin in wood chips, thereby separating the cellulose fibers and processing them into paper.
2、Can paper mills produce caustic soda on-site?
Yes. Many large paper mills install chlor-alkali plants to produce sodium hydroxide on-site to control costs and ensure a stable supply.
3、What chemicals do caustic soda plants produce?
Chlor-alkali plants produce:
Sodium hydroxide (NaOH)
Chlorine (Cl₂)
Hydrogen (H₂)
4、Is membrane separation technology suitable for the paper industry?
Yes. Membrane separation technology can provide high-purity sodium hydroxide, operates stably, and consumes less energy.
