Many industries, industrial power plants, are burning fossil fuels, they are coaling to get their energy while releasing flue gas into the air. Global warming causes greenhouse gas emissions and causes several environmental and social impacts. The capture of carbon dioxide from exhausted flue gas is essential to keep a cleaner environment better. So, capturing or avoiding the formation of dust, NOx, SOx, and CO2 is the central part of the industry, due to environmental and health reasons. There are three methods of capturing CO2 from the flue gas, and one of them is post- combustion capture. Otherwise, there are five options to capture CO2. Chemical absorption is widely applicable in industry, and effectively. That captured CO2 stored some industries and again used that to improve their efficiencies and use them for relevant works.
