I would like to know what components are typically present in waste gas – specifically, what percentage do nitrogen oxides and phenols account for?
Different sources of acidic gases have different compositions.
Mainly hydrogen sulfide, ammonia, and carbon dioxide
There are also fuel gases such as carbon monoxide, hydrogen, and methane
There are volatile organic compounds (VOCs), hydrocarbons, organic sulfides such as thiolines and thioethers, phenols, aromatics, and low-concentration inorganic sulfides such as hydrogen sulfide and ammonia
:Lol, thanks. Could phenol have a red color? Under what circumstances does it change color?
Thank you. Could phenol have a red color? Under what circumstances does it change color? Is the nitrogen oxide content high?
There are volatile organic compounds (VOCs), hydrocarbons, organic sulfides such as thiols and thioethers, phenols, aromatics, low-concentration inorganic sulfides such as hydrogen sulfide and ammonia, biochemical aeration, gases released during anaerobic treatment of wastewater, and gases released during sludge decomposition, etc. These depend mainly on the raw materials, products, and processes associated with each facility.
The latest regulations for nitrogen oxides specify a limit of less than 150 mg/m3; as for the phenol content, the exact value is not known – it depends on the raw materials and the process used in the equipment
RO2 N2 O2 H2O CO H2 CH4 Ash Air; these are generally present, and there are also some substances that arise from different processing stages
Are there crystals? Carbon dioxide has a significant impact, I guess
