【Ten Years of Great Progress in Chemical Engineering Technology】Industrial demonstration unit for STD (desulfurization and denitration integration) with a capacity of 10,000 m3/h, 193–2023

Thread Content

Ten years of rapid development in chemical engineering technology; praise for the prosperous and strong China. This is just a starting point to encourage more participation from everyone. HaiChuan becomes even better with your involvement – we welcome all to join in the forum discussions. Be careful with fire risks as the heat increases in July. ------------------------------------------- On June 6, 2023, the project team from Shenyang Institute of Engineering held an acceptance meeting for the boiler flue gas treatment system renovation project at Liaoning Guorui New Materials Co., Ltd. The “STD (integrated desulfurization and denitration) technology” independently developed by Professor Wu Weicheng’s team at our university has successfully passed the project acceptance test following the construction of an industrial demonstration plant with a capacity of 10,000 m3/h at Liaoning Guorui New Materials Co., Ltd. Professor Wu Weicheng’s team is dedicated to research in the areas of advanced treatment of industrial waste gases and the recovery of low-temperature waste heat from industrial processes. The “STD (Integrated Desulfurization and Denitration) technology” developed by them features integrated desulfurization and denitration, a simple process design, low initial investment, low operating costs, and no temperature drop. Previously, pilot tests of STD technology were conducted on the flue gas treatment systems at Chinalco Fushun Aluminum Co., Ltd., Fushun Mining Group’s Shale Oil Refining Victory Experimental Plant, and Fangda Group Fushun Carbon Co., Ltd., with good results. Liaoning Guorui New Materials Co., Ltd. is a high-tech enterprise of ** level specializing in the production of isostatically pressed special graphite and graphite materials for high-temperature gas-cooled reactors in fourth-generation nuclear power plants; it is also responsible for implementing key scientific and technological projects. The company is in urgent need of solutions to the problem of advanced treatment of exhaust gases during its production process. In May 2022, Professor Wu Weicheng, in collaboration with Professor Zhang Jing’s team from Nanjing University of Science and Technology and Liaoning Provincial Petroleum and Chemical Planning and Design Institute Co., Ltd., developed the first industrial demonstration unit for STD (desulfurization and denitrification integration) technology. Through comprehensive operational testing, the predetermined design objectives were achieved. To date, the project has been in operation for over 1,000 hours. The key performance indicators of all units of the STD device meet the design requirements, and the system operates stably. Tests conducted on-site by a third-party testing company (Liaoning Jiarui Environmental Testing Co., Ltd.) show that the exhaust gases emitted meet or even exceed the ultra-low emission standards.
