Definitions
- the invention relates to a method for purifying a gaseous, liquid or aerosol composition containing at least one pollutant consisting of a volatile inorganic compound (CIV), a siloxane, and / or a functional volatile organic compound (VOC). ).
- CIV volatile inorganic compound
- VOC functional volatile organic compound
- the emission of air pollutants is regulated by law because of their negative impact, including on human health, biological resources, ecosystems and climate.
- VOCs Volatile Organic Compounds
- greenhouse gases may be Volatile Organic Compounds (VOCs) and / or greenhouse gases.
- VOCs can cause eye and throat irritation, allergies, headaches, asthma attacks, nausea, etc.
- VOCs also play an important role in the troposphere, leading to an increase in the amount of ozone in the air.
- Ozone is produced inter alia from nitrogen dioxide under the effect of solar radiation.
- the formed ozone then reacts with nitric oxide to produce nitrogen dioxide.
- the previous cycle is modified by the carbon radicals (strong oxidants) which replace the ozone during the formation reaction of nitrogen dioxide, which leads to an increase in the amount of ozone.
- the increase in the amount of ozone with its consequences for the environment and health, is therefore partly linked to VOC emissions.
- the concentrations of greenhouse gases in the atmosphere have increased since the nineteenth century mainly for human reasons with a new record in 2014 by the World Meteorological Organization (WMO).
- WMO World Meteorological Organization
- the increase in the main greenhouse gases is mainly due to certain human activities, including the massive use of fossil fuels (coal, oil).
- Greenhouse gases such as carbon dioxide (which accounts for nearly 70% of anthropogenic greenhouse gas emissions) and methane, are not necessarily dangerous for humans, biological resources and ecosystems, but their emissions are at the root of global warming, a phenomenon that has many negative consequences for humans and their environment.
- oxidants such as bleach.
- these oxidizing washing methods have the major disadvantage of generating in the discharges oxidation by-products themselves polluting and sometimes very strongly smelly.
- these oxidants are unstable and their handling is dangerous.
- biogas is a combustible gas obtained by fermentation, also known as anaerobic digestion, of organic waste of animal or vegetable origin in the absence of oxygen, which mainly comprises methane as well as carbon dioxide.
- biogas as a source of renewable energy rather than reject it at the atmosphere.
- Biogas is valued in different ways. It can, after a light treatment, be upgraded near the production site to provide heat, electricity or a mixture of both (the high carbon dioxide content reduces the calorific value of the biogas, increases the costs of compression and transport and consequently limits the economic value of upgrading biogas away from the production site).
- Biogas can also be purified to allow wider use.
- the biogas can be subjected to a purification which consists of removing unwanted substances and traces of pollutants (ammonia, sulfur compounds, VOCs including organochlorines, siloxanes) from crude biogas and increasing its methane content (in particular by removing CO 2 ) to produce a gas comparable to natural gas.
- pollutants ammonia, sulfur compounds, VOCs including organochlorines, siloxanes
