What are paper and pulp mills?
A pulp mill is a manufacturing facility that converts wood chips or other plant fibre source into a thick fibre board which can be shipped to a paper mill for further processing.
Hazardous chemicals used in pulp and paper mills require careful handling and continuous monitoring to minimize threat to workers, processes and nearby communities.
Typical gases released during the processes
The most harmful gases that are released by pulp and paper mills are as follows:
Hydrogen Sulphide (H2S) - during the process - glue holding woodchips together, known as lignin, breaks down and mixes with the white liquor producing H2S.
Oxygen (O2) – bleaching of pulp is achieved through an oxidation process where Oxygen is used to dissolve undesired colour of pulp stock or chlorination using Chlorine (CL2) or Chlorine Dioxide (CLO2).
Hydrogen Peroxide (H2O2) and Ozone (O3) – these gases are common replacements in some establishments. These are the deadly vapours released during and after the oxidation and chlorination process.
Natural gas (CH4) also known as Methane – after bleaching, pulp is sent to the burner decks for drying. Methane is used to heat the burner which consequently presents a combustible hazard.
Here at Point Safety we provide workers in a variety of numerous industries, personal gas monitors. These are to clip onto their overalls and work wear. Likewise, for paper and pulp mills, we have a range of multi and single gas monitors available to detect the gases mentioned above continuously over a period of time. We also offer the option of being able to download data from the gas monitor, in order to analyse the data collected. As well as personal gas monitors, we also provide fixed gas detection systems, for further information on these, please contact email@example.com
