The CO content in the reformed hydrogen is high
Thread Content
The CO content in the hydrogen produced through reformation and in the circulating hydrogen is high, around 20 ppm. Could anyone please analyze what causes this? Is it due to the relatively high water content in the refined oil, at 50–70 ppm?

https://wenku.baidu.com/view/f95bd85a3b3567ec102d8a12.html An analysis of the reasons for unsatisfactory levels of carbon oxides in hydrogen produced through continuous reforming; relevant papers on Baidu Wenku indeed indicate that this is related to the water content in the recycled hydrogen gas! ! ! You can take a look at the relevant papers
Our unit shouldn’t be the cause; the purge gas at the bottom of our reactor exchanges heat with the oil and gas at the reactor outlet, there is no steam exchanger

In short, it’s a balance issue with water and chlorine – in other words, the chlorine content is too high, which leads to an intensified cracking reaction. Also, isn’t the reforming hydrogen passed through any purification device? What is the content of water in the circulating hydrogen as measured by an online analyzer? The paper discusses the use of low-pressure steam for heating the regenerator leaching gas heater; leakage of low-pressure steam from the heat exchanger into the leaching gas leads to an excessive water content and an imbalance between water and chlorine. What you are referring to is the reactor displacement heater! The two are different!
I would like to ask if your online water analyzers are all reliable?
May I ask the original poster, has the problem been resolved? Is it caused by a high water content or some other reason?
This is excellent material that is worth studying and drawing lessons from!
