Corrosion of steam generator at the top of benzene tower in ethylbenzene plant
Thread Content
The steam generator at the top of the benzene tower of the ethylbenzene unit continuously leaks, and pitting pits appear in the tube bundle in the picture. Is it related to the use of demineralized water, and what are the operating standards for steam generation? ? ?
Others such as generator material, service life, etc.
The tube bundle is carbon steel and has been in use for 4 years. We know that it is time for replacement, but the cause of the pitting corrosion on the surface of the tube bundle is not yet clear.
Our benzene tower does not have a steam generator
So how do you remove the heat? ?
