Reduction of SO2 emissions, air pollution control, and improve the quality of the environment is an important issue for current and future environmental protection in China quite a long time.SO2 control technology a lot, such as improving the energy structure, the use of cleaner fuel, flue gas desulphurization technology is the reduction of SO2 emissions irreplaceable technology. To date, the types of flue gas desulphurization technology are hundreds of species from the absorber terms of the types of limestone desulfurization process, ammonia desulfurization technology, the magnesium desulfurization technology, dualalkali FGD technology, seawater desulfurization technology. Ammonia desulfurization technology with its small footprint, operating costs and economic, byproducts of high value, no secondary pollution and other advantages, occupy a certain market share in the desulfurization industry. ASPEN PLUS chemical process simulation system is the Massachusetts Institute of Technology in the United States in the late 1970s, research and development of largescale chemical process simulation software. By the the ASPEN PLUS technology panies to market in the early 1980s, the software after 20 years of continuous improvement, expansion and improvement, has launched more than a dozen versions, known as certificate universally recognized largescale process simulation software. Rigorous and uptodate method of calculating the calculation of the unit and the entire process, providing accurate unit operation models, you can also evaluate the existing device optimized operation or new construction, renovation device optimized design, the user is also able to process calculation infrastructure and operating costs at the same time to estimate the technical and economic evaluation of the process.The experimental use of process simul
