Ladies and gentlemen, the three methods for treating sulfur-recovering flue gases are dry method, wet method, and direct combustion method. How are the dry method and wet method explained?
Dry methods such as activated carbon absorption, wet methods such as aqueous ammonia absorption
Dry methods generally refer to physical absorption, while wet methods are more common, such as the ammonia method, sodium method, calcium method, etc
The dry method refers to the use of solid adsorbents for adsorption； The wet method refers to the use of a liquid for adsorption, which is divided into physical absorption (such as low-temperature methanol washing) and chemical absorption
So the dry method is the same as what was mentioned on the first floor, right? It mainly involves activated carbon adsorption? :)
What method is used for sulfur recovery? The exhaust gas contains SO2; if that’s the case, there are various dry processes for removing sulfur dioxide, and it doesn’t necessarily involve activated carbon alone
