Flue gas desulfurization
SO 2 is an acid gas and therefore the typical sorbent slurries or other materials used to remove the SO 2 from the flue gases are alkaline The reaction taking place in wet scrubbing using a CaCO 3 slurry produces calcium sulfite CaSO 3 and may be expressed in the simplified dry form as CaCO 3 s SO 2 g → CaSO 3 s CO 2 g When wet scrubbing with a Ca OH 2 hydrated lime. What Are Tailings In Limestone Mining Ultrafine Grinder· Some high taste limestone tailings can be processed into related products such as desulfurization powder metallurgical high calcium powder light calcium carbonate etc to further expand their application range The most common method currently used for desulfurization in power plants is limestone desulfurization which is also a method with significant desulfurization effects . Desulfurized limestone powder production processThe collected limestone powder product is sent to the stone powder bin by the conveying device for use in desulfurization The unqualified particles are smashed to the wall of the cylinder after being separated by the separator and are returned to the grinding mill for grinding The whole system is operated under negative pressure and the dust does not overflow to achieve a clean effect . Power plant desulfurization Crushers Grinding Mill In addition to the dry desulphurization now more than 80% of flue gas desulfurization adopts wet desulphurization which is the world s most widely used It commonly includes Limestone gypsum desulfurization NaOH desulfurization MgO desulfurization of abundant raw materials and low cost Limestone gypsum is most widely used . limestone vertical mill for desulphurizationLimestone vertical grinding mill to be very helpful in Power Plant Desulphurization Industry Limestone is currently a desulfurization agent commonly used desulfurization process of power plant the general fineness of finished products is 325mesh and sieve more than 10% of the powder is more suitable for power plant desulfurization industry
