摘　　要：介绍云南磷化集团有限公司800 kt/a硫黄制酸装置负荷提升至103%运行时,转化四段工艺温度出现超标运行的情况。结合装置运行实际和工艺管道、设备布局及工艺技术要求等制定工艺技术改造方案。技改完成后,转化四段工艺温度得到有效控制,满足运行要求,装置运行效能得到提升。The situation that the temperature of the fourth stage conversion process exceeds the standard is introduced when the load of the 800 kt/a sulfur-based sulfuric acid plant of Yunnan Phosphate Chemical Group Co.,Ltd.is increased to 103%.By combining the actual operation of the device,the process pipeline,equipment layout and technical requirements,the technical transformation plan is formulated.After the technical transformation,the temperature of the fourth stage conversion process is effectively controlled,meeting the operation requirements,and the operation efficiency of the device is improved.
