加拿大CIL阳极保护管壳式酸冷却器的应用

Application of Anodically Protected Stainless Steel Shell-and-Tube Acid Coolers Introduced from CIL, Canada

大连化学工业公司化肥厂从加拿大开米蒂克斯公司引进了不锈钢阳极保护管壳式酸冷却器,一台用于干燥酸,一台用于吸收酸,文中介绍了酸冷器的结构和有关参数及投产运行情况。经一年多的生产实践,该设备运行情况良好,无腐蚀情况产生。另对酸冷器与铸铁排管进行了经济比较。

The Fertilizer Plant of Dalian Chemical Industry Company introduced theanodi-cally protected stainless steel shell-and-tube acid coolers(APC) from CIL, Canada. O-perating practice indicates that the APC work satisfactory and no corrosion is observed for over one year's service. The structure and parameters of APC are described and the economic evaluate of APC vs cast iron cascade cooler is given.
