| At present, the environmental pollution caused by the emissions of sulfur dioxide has drawn the attention of governments. Our country loss more than 10 billion yuan every year. Therefore, the government started the project of Power Plant's Flue Gas Desulfurization during the Eleventh Five-Year plan Period. Limestone is the preferred desulfurizer because of its abundant resources and low prices.First this article use CaO, Ca(OH)2, CaCO3 as desulfurizer for desulfurization experiences, and then choose different kinds of compounds as additives. The results showed that calcium sulfur ratio, the kind of additive and its quantity has certain effects on the desulfurization efficiency; different additive has different effect on desulfurization efficiency and desulfurization products. The effect of spraying water on flue gas desulfurization efficiency has been experimentally investigated.Based on the experiences, the desulfurization process was simulated with PROâ…¡. By selecting the right unit operation models, proper thermodynamics equation and kinetic equation, the simulation results can reflect accurately the effect of various factors on desulfurization efficiency. |
