Abstract[English]
According to the World Health Organization, 7 million people die annually due to inhaling exhaust gases containing SO2 and NOX from power plants. The majority of these emissions come from fossil fuel combustion in thermal power plants and diesel engines. Industrial development is necessary for providing electricity, but the growth in societies will lead to an increase in pollution. Existing filters are costly, discouraging power plants from using them. This invention prevents smoke from power plants, ships, and locomotives from entering the atmosphere. The process involves removing vaporized particles and converting SO2 gas into sulfuric acid, which can be used in various industries. The remaining gases, including NOX, are converted into nitric acid and other useful compounds through a series of steps. The final output contains only minimal CO gas, which can be controlled through improved oxidation methods in fuel combustion.[French]
Selon l'Organisation Mondiale de la Santé, 7 millions de personnes meurent chaque année en raison de l'inhalation de gaz d'échappement contenant du SO2 et des NOX émis par des centrales électriques. La plupart de ces émissions proviennent d'une combustion de combustible fossile dans des centrales thermiques et des moteurs diesel. Le développement industriel est nécessaire pour fournir de l'électricité, mais la croissance dans les sociétés conduira à une augmentation de la pollution. Les filtres existants sont coûteux, ce qui décourage les centrales électriques de les utiliser. La présente invention empêche la fumée dégagée par les centrales électriques, navires et locomotives de pénétrer dans l'atmosphère. Le procédé consiste à éliminer les particules vaporisées et à convertir le SO2 gazeux en acide sulfurique, qui peut être utilisé dans diverses industries. Les gaz résiduels, y compris les NOX, sont convertis en acide nitrique et autres composés utiles par l'intermédiaire d'une série d'étapes. La sortie finale contient uniquement une quantité minimale de CO gazeux, qui peut être contrôlée par l'intermédiaire de procédés d'oxydation améliorés dans la combustion de carburant.
