Like a wet scrubber, a dry scrubber can remove both harmful gases and particles from an exhaust stream. Dry scrubbers are mostly used to remove acids from gas exhausts that result from combustion processes. In these applications, the dry sorbent is an alkaline slurry. As the gas comes into contact with the alkaline substance, the acid is ...

WhatsApp: +86 18203695377ABSTRACT. Wet flue gas desulfurization (WFGD), using limestone with forced oxidation (LSFO), is a common Flue gas desulfurization (FGD) process where limestone reacts with SO 2 to produce gypsum (CaSO 2 O). In South Africa, Eskom's Kusile Power Station utilizes conventional wet ball milling to grind highgrade limestone (96% CaCO 3) to 95% passing 45 µm prior to use in the FGD scrubber.

WhatsApp: +86 18203695377Industrial air scrubbers can be either "dry" or "wet." Dry scrubbers use solid materials for pollutant removal, while wet scrubbers use liquid solvents. Both remove gas pollutants and related odors from industrial exhaust streams. In general, wet scrubbers achieve a higher level of pollutant removal than dry scrubbers.
WhatsApp: +86 18203695377How to choose dry and wet ball mill. 1. Correctly choose the feeding way of dry grinding and wet grinding. Whether feed the material dry or wet depends entirely on the subsequent operations in the ball mill and the nature of the produc Some materials require dry grinding because they will undergo physical or chemical changes after adding water.
