Adjusting the temperature of each catalyst layer in the acid production process from smelting flue gas using the temperature difference method
Thread Content
Help: The temperature difference method can be used to control the temperature of each catalyst layer in the conversion process. Does anyone know the specific procedures for applying this \"temperature difference method\"?
Simply put, it’s about stabilizing the gas concentration and flow rate, and identifying the highest temperature rise section by section from front to back. The temperature rise in the last two sections is lower, making it difficult to detect changes; therefore, the changes in exhaust SO2 emission concentrations can be analyzed instead. It’s much easier if there’s online analysis (it’s generally available these days).
The conversion section in the \"Fertilizer Engineering Series – Sulfuric Acid\" provides an introduction to the maximum temperature difference method, which was first proposed by Zheng Chong from Beijing University of Chemical Technology; he mentioned it during his lectures abroad.
