Paper is closely connected to our lives. Everything from toilet paper, books, packaging materials, newspapers, and notebooks proves our huge demand for paper. To meet people's needs, paper mills have introduced new equipment and improved their papermaking processes, significantly increasing efficiency and saving time and labor costs.

The toxic gases in paper mills mainly come from the pulping process. Specifically, pulping is a chemical production process using plant fibers as raw materials, so under biological and chemical reactions, gases that are toxic and harmful to humans are produced.

The main sources of toxic gases in paper mills are as follows:

  • Pulp pits: Ammonia, hydrogen sulfide, carbon monoxide, etc.
  • Washing machines: Chlorine, hydrogen peroxide, chlorine dioxide, ozone, etc.
  • Pulping workshops: Sulfur dioxide, methyl sulfide, hydrogen chloride gas, etc.
  • Sludge settling tanks: Carbon monoxide, ammonia, hydrogen sulfide, foul-smelling gases, etc.
