SCEDI pays attention to the technological progress and technology development and commits to appling the mature scientific achievements to the engineering design actively.Especially in sulfuric acid and phosphorus chemical industry, we have accumulated a wealth of engineering design experience and research achievement ，applied to specific engineering design, carried forward the development of recycling economy and achieved obvious economic and social benefits. A number of thesises written by our team of experts such as senior engineer  professor Wenzhuo Zhong、Shugang Wei etc. which summaried in the way to promote recycling economy development of scientific achievements and the successful experiences in specific engineering design sulphur& phosphorous chemical industry have published in the key to China’s technology journal—<Sulphuric Acid Industry>，<Collected Papers of China National Seminar on Development of Sulphur Phosphorous Industry >2000，<Collected Papers of the 12th National Chemical Sulfuric Acid and Posphate Design Technology Center Annual Meeting》July,2008，the 13th Annual Meeting Collected Papers etc. 《Neutralization and Filtration of Liquid Sulfur inSulfur-burning Sulfuric Acid Plants》,Wenzhuo Zhong ,has excerpted on <Chemical Abstracts> which published by the American Chmical Society.<Sodium-Based FGD Process for Coal-Fired Power Station Based on a Recycling Economy System> written by W.Zhong and S.Wei etc.was read in Sulphur Annual Meeting that hold in Rome,Italy, on November,2-5,2008,also recorded and published in the annual meeting proceedings. Furthermore,it’s won the “Excellent Paper” second prize of National Chemical Sulfuric Acid and Phosphate Design Center in 2008. <Making sulfuric acid of Sodium-Based FGD Process for Fossil-fired Power Satations Based on a Recycling Economy System> won the second prize of Excellent Paper warded by National Chemical Sulfuric Acid and Phosphate Design Center.
