Flue gases are pollutants generated by combustion, including from heavy industry, energy, wood fires, and cars. They contain various compounds harmful to the environment and human health. Control methods include prevention, efficiency improvements, and scrubbing with filters. Scrubbing can also be profitable, as the food industry uses purified carbon dioxide. Emissions are regularly tested for adequate scrubbing.
Exhaust gases are by-products of combustion that are classically discharged through long pipes known as flues. These gases are treated as pollutants. Flues can be called “chimneys” and can be found in the form of chimneys, ducts, or simple pipes. Large amounts of waste gases are generated around the world every day, with heavy industry and the energy industry in particular responsible for a huge percentage of the total generated. These gases are also created whenever people build a wood fire or drive a car.
The contents of the fumes are quite variable. The medium being burned can contribute a number of different compounds, and the conditions under which combustion occurs can also generate more or fewer emissions. Incomplete combustion at low temperatures or in poorly managed plants, for example, tends to generate more pollution.
Some things commonly found in exhaust gases include: water vapor, carbon dioxide, nitrogen, particulate matter, oxygen, carbon monoxide, nitrous oxide, hydrocarbons, and sulfur oxide. Some of these compounds are potentially harmful to the environment, making these gases a cause for concern among environmental advocates. Exhaust fumes can also be dangerous to human health, as could happen if they were trapped in an air inversion that pinned them to the ground for several days, forcing people in the area to inhale dangerous pollutants that could damage their lungs. .
There are several ways flue gases can be controlled, and the processes that produce them are often heavily regulated to reduce emission levels. One of the best methods of control is to avoid generating them altogether, either by using alternative technologies, improving efficiency levels in a plant, or by investigating ways in which operating conditions could be improved to reduce the production of combustion by-products. Gases that cannot be prevented can be trapped using filters and scrubbers that clean the outgoing air of the fumes so that when it is released into the environment it contains mostly harmless components.
Indeed, exhaust gas scrubbing can be profitable even for an experienced company. For example, the food industry uses carbon dioxide and is willing to pay for purified carbon dioxide extracted from flue gases. This usage also solves the problem of what to do with the pollutant once it has been removed from the flue. Flue emissions are regularly tested to determine whether or not the gases are adequately scrubbed before being discharged into the environment.
