Sodium-calcium double-alkali desulfurization technology process and optimization control instructions
Sodium-calcium double-alkali method is one of the more commonly used desulfurization methods. This method has been successfully applied in large scale in foreign countries (such as Japan and the United States). There are at least 50 sets of double-alkali method in Japan and the United States. Industrial boilers, the larger one is the United States. Qingdao Continental Control is familiar with the research and development and implementation of various production processes, optimization control, control system integration technology and enterprise information management software in the process industry. The products and system solutions have been widely used in thermal power, chemical industry, environmental protection (desulfurization and dust removal), Papermaking, grain, smelting, underground coal gasification and other industries have been widely recognized by experts and users. Continental Control Engineering Co., Ltd. has strong cooperation with GE Energy and has provided control systems for well-known domestic and foreign desulfurization equipment manufacturers. The integrated design of the desulfurization control system and unit units using GE Energy's DCS (XDPS) achieves FGD It is seamlessly connected with DCS (XDPS), so that DCS (XDPS) can more optimally control the desulfurization emission index. The following is the double alkali desulfurization process
The double-alkali method is to use a soluble alkaline solution as an absorbent to absorb SO2, and then use lime milk or lime to regenerate the absorbent solution. Because different types of alkali are used in the treatment of the absorbent and absorbent solutions, it is called Double alkali method. Sodium-calcium double-alkali method uses sodium carbonate or sodium hydroxide solution as the first base to absorb SO2 in the flue gas, and then uses lime or slaked lime as the second base to process the absorption liquid, and the regenerated absorption liquid is sent back to the absorption tower for circulation. use. Because sodium lye is used as the absorption liquid, there is no scaling and slurry blocking problems, and the sodium salt absorption rate is faster than the calcium salt rate. The required liquid-gas ratio is much lower, which can save power consumption. Sodium-calcium double-alkali method has been successfully applied in large scale in foreign countries (such as Japan and the United States). At least 50 sets of double-alkali method desulfurization devices have been successfully used in power stations and industrial boilers in Japan and the United States. There are many sets of mature engineering applications in China.
