Wet limestone - gypsum flue gas desulfurization technology Technical Description: Within the flue gas in the absorber layer from the spray nozzle countercurrent contact with the limestone slurry reaction, the amount of fresh absorbent added value through continuous monitoring of the PH control. Absorber of low PH value of the lower limestone is conducive to the realization of the dissolution and oxidation, the higher the PH value of the previous paragraph is conducive to the reaction of sulfur dioxide absorption, improve the desulfurization efficiency. Process characteristics: Desulfurization efficiency, one-time investment is low; Automatic control system with the absorber can reduce operating costs and achieve real-time operational control; Absorbent cheap and easy to get high purity gypsum by-product, a higher value of the commercial use; Special nozzle clogging, the life of 30 years; Able to adapt to unit capacity, high concentrations of sulfur dioxide in the flue gas conditions; Use of special anti-corrosion processes and materials, system main equipment life up to 30 years. Wet flue gas desulfurization MgO
Technical Description: Magnesium is a wet desulfurization performance of advanced and mature technology, economy and good desulfurization technology, is a national "Tenth Five" 863 crystallization of high technology, many countries competing for the development process. Reserves and production of magnesium oxide ranked first in the world and unique location. The process is suitable for China, the popularization trend gratifying. Process characteristics: Strong reactivity of magnesium oxide and sulfur dioxide, absorption speed, high efficiency desulfurization; System is reliable, equipment without clogging, scaling and other issues; Consumed less magnesium, system, small footprint, power consumption province, low operating costs; Magnesium sulfate heptahydrate-product of high commercial value, no secondary pollution; Wide adaptation for treatment of high, medium and low-sulfur coal. Wet plus magnesium lime (stone) flue gas desulfurization
Technical Description: Wet plus magnesium lime (stone) flue gas desulfurization process is magnesium oxide containing lime (stone) as raw materials, desulfurization reaction is mainly done by one of magnesium hydroxide to produce calcium hydroxide, magnesium sulfate and reduced to hydrogen reaction and regeneration magnesium desulfurization tower back end products to high-purity gypsum. The process to add magnesium lime as the sorbent, which can effectively enhance the desulfurization activity of lime to improve absorption. It combines excellent desulfurization performance of magnesium and calcium-based low-cost advantages, but also to avoid the problem of calcium-based desulfurization scaling. Plus magnesium lime (stone) of sulfur dioxide absorption capacity of the slurry higher than 10-15 times the lime, the system greatly reduces the required ratio of liquid to gas. Process characteristics: High desulfurization efficiency, stable and reliable; System, low operating costs, cycle power is small; Investment, small footprint; Automatic suppression system scaling; By-product of high purity, liquid efflux less.
