Weitere Informationen
The application and challenges of advanced process control (APC) technology in wet-process phosphoric acid production is discussed. Taking the 2×300 kt/a phosphoric acid plant of Yunnan Three Circles-sinochem Fertilizer Co., Ltd. as an example, the application of APC technology in the thickening section, reaction section and concentration section is introduced, including the control strategies, operation methods and precautions of each section. The application effects of APC technology in wet-process phosphoric acid production are analyzed, such as improving production stability, reducing operation frequency, improving automatic control rate and advanced control application rate. At the same time, the challenges faced by APC technology in the application process are pointed out, including equipment failures and abnormal conditions, configuration errors and incomplete technical transformation. Finally, the application of APC technology in wet-process phosphoric acid production is summarized and prospected. [ABSTRACT FROM AUTHOR]
