The papermaking industry is a crucial element of modern society that is responsible for the production of various types of paper products that we use daily. However, the production process of paper involves several stages, including bleaching, which emits various gases that may pose threats to the environment and human life. Therefore, it is essential to identify these gases and the potential hazards they present to aid in their detection and control.


Bleaching is an integral process in papermaking, as it removes impurities from the pulp and enhances the paper’s brightness and purity. However, this process involves the use of chlorine, which reacts with the pulp to form various gases, such as chlorine dioxide, chlorine gas, and hypochlorous acid. These gases are hazardous to the environment and human health when released into the air, as they can cause respiratory disorders, skin irritation, and other chronic diseases.


To control the emission of these gases, it is essential to detect their presence in the air. Several detection methods are available, such as gas sensors, gas chromatography, mass spectrometry, and infra-red gas analyzers. Using gas inspection device is one of the most accurate, reliable and fast methods.
