摘  要:
我公司600kt/a硫磺制酸装置转化器一段催化剂层粉化、结块,阻力过快上升,被迫频繁停车筛分催化剂。从工艺、设备、操作等方面进行了分析,找到阻力上升的根本原因是转化器一段催化剂层的隔板开孔率小,气速过快(4.95m/s)所致。经将隔板开孔率提高,气速降到2.56m/s后,转化器一段催化剂层的阻力稳定。

摘  要:
For the section I catalyst bed layer of powdering and scaling,the resistance of converter quickly increases in a 600 kt /a SA plant by sulfur-burning,the operation has to frequently stop for screening of catalyst.Based on analysis of the technology,equipment,operations and other aspects,the basic reason of increased resistance are small diaphragm open porosity in the section I catalyst bed layer of the converter,and higher gas velocity(4.95 m /s).After increasing diaphragm open porosity,the gas velocity decreases to 2.56 m /s,the section I catalyst bed layer resistance of the converter is stable.
