摘要
分析了硫酸装置中影响露点腐蚀的主要因素,以硫磺制酸、硫铁矿制酸和硫化氢湿法制酸项目提供的工艺参数为例,分别计算了通过余热回收系统设备的炉气露点,并从余热回收系统设备设计的角度提出防止露点腐蚀的措施。
Major factor which have influence on the dew point corrosion in the sulfuric acid is analyzed,and by taking the example of process parameters provided by the sulfur-burning sulfuric acid,pyrite-based sulfuric acid and H2S-based wet-process sulfuric acid projects,the dew point of furnace gas going through the equipment in the waste heat recovery system is respectively calculated,and measures against dew point corrosion in terms of equipment design for the waste heat recovery system are proposed.
