<\/p>\n\n\n\n

Volatile Organic Compounds (VOCs) and dust are key pollutants<\/strong> in many industrial sectors, with environmental implications and health risks. These emissions are particularly prevalent in the chemical, pharmaceutical, automotive, wood, plastics, paint, coatings and food industries.<\/p>\n\n\n\n

Every industrial process<\/a>, from the handling of raw materials to final manufacture<\/strong>, contributes to the release of these substances into the atmosphere. These emissions can be simultaneous or sequential, depending on the specifics of the industrial operations and the materials used. The emission of VOCs and dust is often accompanied by odor nuisance and can present a risk of explosion (ATEX), which requires rigorous management and appropriate preventive measures to minimize the impact on the environment and<\/strong> public health<\/strong>.<\/p>\n\n\n\n

VOC and dust emissions in the chemical and pharmaceutical industries. Odors and associated ATEX risks. <\/h2>\n\n

What operations emit dust and VOCs in the chemical industry?<\/h3>\n\n

In these sectors, several industrial processes emit VOCs and dust<\/strong> simultaneously, or within a short space of time. These emissions occur during the movement, use or manufacture of chemical materials. Here are a few examples of operations. <\/p>\n\n

Logistics operations <\/h3>\n\n\n\n

The unloading, handling and storage of raw materials in powder or granulated form generate dust. If these raw materials contain VOCs<\/strong>, they may emit them during these operations. <\/p>\n\n\n\n

Material operations<\/h3>\n\n\n\n

Mixing or grinding solid chemical substances produces fine particles that become airborne. If these substances contain volatile organic compounds<\/strong>, VOCs will be emitted simultaneously.<\/p>\n\n\n\n

Chemical synthesis<\/h3>\n\n\n\n

During chemical synthesis, the reaction process can produce solid particles, by-products of the reaction. Similarly, the use of reagents and solvents, or the generation ofoff-gases<\/strong>, contribute to VOC emissions.<\/p>\n\n\n\n

Drying and heating operations <\/h3>\n\n\n\n

These operations can generate both particles and VOCs<\/strong>, since they often involve evaporating solvents and obtaining dry products. Gas flow from solvent evaporation and product movement during drying can lead to the formation of particles.<\/p>\n\n\n\n

Packaging of VOC- and dust-generating products <\/h3>\n\n\n\n

The packaging and conditioning of <\/strong>powdered or granulated chemical products <\/strong>will generate dust and VOCs if these products contain them. <\/p>\n\n\n\n

Odor nuisance associated with VOC and dust emissions in the chemical industry<\/h2>\n\n

In addition to the risks associated with dust and VOCs,<\/strong> some of these chemical substances also cause odor nuisance. These producers of unpleasant odors include :<\/p>\n\n

Solvents and organic compounds used in various chemical processes, or their interaction with other chemical substances, emit :<\/p>\n\n
