I need help figuring out where the corrosion-prone areas are in the process of producing hydrogen via light hydrocarbon steam reforming
Thread Content
Experts, I’m seeking advice on which parts are prone to corrosion in the hydrogen production process via light hydrocarbon steam reforming Including, where are the vulnerable areas in the residual heat system that are prone to leakage?
The areas prone to leakage in waste heat boilers are the fillet welds at the tube sheet tube ends, and the roots of the fillet welds at the shell connection tubes
Areas that are prone to corrosion are mainly those with acidic vapors and acidic water
Areas prone to corrosion are those where CO2 and H2O are present, mainly the conversion outlets, medium-pressure conversion outlets, various water separation tanks, as well as the pipelines related to acidic water. In waste heat boilers, the areas prone to leakage are the safety valves and the on-site venting systems of the steam drums.
Regarding the waste heat recovery section, to prevent dew point corrosion; it seems that hydrogen corrosion is not apparent in the short term~
