三氧化硫发生罐局部腐蚀原因分析

Analysis of Part Corrosion of Sulfur Trioxide Generator

制备磺酸化物使用三氧化硫为磺化剂是通常方法,三氧化硫较为简便的制备方法,即将发烟硫酸进行加热,驱出三氧化硫。这一过程由于设备安装不合理,常常引起三氧化硫发生罐局部腐蚀,经测试、分析找出腐蚀原因,

Sulfur Trioxide is prepared by heating the fumed sulfuric acid.The process commonly bring the part corrosion of generator,the corrosion causes and solution were discussed in this paper.
