Volatile Organic Compounds, commonly referred to as VOCs, are a group of organic chemicals that are characterised by their high vapour pressure at room temperature. This property leads to significant evaporation into the atmosphere, contributing to air pollution and posing various health risks. VOCs are found in numerous industrial processes and everyday products, making their control and abatement essential for environmental protection and public health.
Sources of VOCs
VOCs originate from both natural and anthropogenic sources. In industrial settings, they are commonly emitted during the production and use of chemicals, pharmaceuticals, petrochemicals, and in processes such as bitumen production/storage, spray painting and soil remediation. They are also commonly formed during the decomposition of municipal and industrial wastes in landfills. Common VOCs include acetone, benzene, siloxanes, toluene, xylene and isocyanates such as TDI and MDI.
Impact of VOCs on Health and the Environment
The presence of VOCs in the atmosphere can have severe implications for both human health and the environment. Short-term exposure to high levels of VOCs can cause eye, nose and throat irritation, headaches and nausea. Long-term exposure can lead to more serious health issues, including liver and kidney damage, and an increased risk of cancer.
Environmentally, VOCs play a significant role in the formation of ground-level ozone and smog, contributing to respiratory problems and other health issues in urban areas. They also contribute to the degradation of indoor air quality, which can be particularly concerning in enclosed spaces.
Regulatory Standards and Compliance
In recognition of the dangers posed by VOCs, regulatory bodies have established stringent guidelines to control their emissions. In the UK, for example, the 2019 Clean Air Strategy emphasises the reduction of VOCs and NH3 emissions as part of broader efforts to improve air quality. Compliance with emissions regulations is critical for industries to avoid fines and operational disruptions, as well as to contribute to public health and environmental sustainability.
VOC Abatement Solutions by Puragen
At Puragen, we specialise in providing advanced solutions for VOC abatement, leveraging the superior adsorption properties of activated carbon. Our products, such as FiltraCarb® EX64 and EXR4, are designed specifically for the efficient removal of standard VOCs. Other activated carbons are also used in odour control systems to eliminate inorganic compounds like hydrogen sulfide (H2S) and ammonia (NH3), enhancing air quality in industrial and residential areas.
Applications of Activated Carbon in VOC Control
Activated carbon is employed in various applications to manage VOC emissions effectively:
VOC Removal
FiltraCarb® products capture and remove a wide range of VOCs from industrial emissions, ensuring cleaner air.
Odour Control
Activated carbons impregnated with specific chemicals target and neutralise odour-causing volatile compounds.
Acid Gas Removal
Specialised activated carbons are used to remove acidic gases from industrial process streams.
Multi-Pollutant Control
Comprehensive systems that address multiple contaminants simultaneously, improving overall air quality.
Personal Protection Equipment
Activated carbon filters in respirators and escape hoods protect workers, first responders and military personnel from hazardous gases.
