高温含杂醋酸环境中设备选材的探讨

APPROACH AND DISUSSION OF MATERIALS SELECTION FOR EQUIPMENT IN HIGH TEMPERATURE IMPURITY CONTAINING ACETIC ACID ENVIRONMENT

对接触高温醋酸生产装置腐蚀行为及其选材进行了讨论.提出了醋酸对材料的腐蚀,既要考氧的影响,也不能忽视杂质的作用;对铜、不锈钢、钛三种材料作为高温醋酸塔器用材进行了评价比较.

The corrosion behavior and materials selection of productive plant contacting high temperature acetic acid have been discussed. It is raised that the corrosion of materials in acetic acid, oxygen effect and impurity effect should be considered. And an appraisal and comparison of copper, stainless steel and titanium for usefel materials of columns in high temperature acetic acid have been made.
