I would like to ask everyone about the corrosion situation in PTA plants

Thread Content

I need to conduct a corrosion analysis of the hydrogenation and oxidation units in a PTA plant. Preliminarily, the potential corrosion mechanisms for the oxidation reactor include pitting caused by bromoacetic acid, selective corrosion of titanium material due to iron ion contamination, erosion corrosion, and galvanic corrosion between Ti and the adjacent 316L material. The potential corrosion mechanisms for the hydrogenation unit include temper embrittlement, high-temperature hydrogen damage, pitting caused by bromoacetic acid, and Johnson tube galvanic corrosion. It is necessary to analyze specifically under actual operating conditions to determine whether these corrosion mechanisms are at work. I would like to ask everyone now: what is the corrosion condition of your hydrogenation (lined with 304L) and oxidation (lined with Ti) processes? Is the uniform thinning and pitting severe? There are even more data on the corrosion rate! Dear gentlemen and ladies, those who have money can contribute financially, while those who don’t can still show their support. Those who provide valuable responses will receive generous rewards
